This information is to help Building Owners & Home Owners to better understand how these cleaning agents work. We should first get ourselves familiar with the different types of exteriors textures there are used in today’s market. The easiest way will be to divide the materials into eleven categories. The first will be Stucco, second Vinyl, third Wood, fourth Fiber Cement, fifth Cement in general, sixth Engineered Wood Siding, seventh Brick, eighth Synthetic Stone, ninth Metal, tenth Composition, eleventh and lastly Composite Materials such as Trex.
PLEASE REMEMBER THIS INFORMATION IS TO BE USED AS A GUIDE AND THAT NOT ALL STATEMENTS WILL BE TRUE IN EVERY CASE. THIS GUIDE IS NOT INTENDED TO MAKE THE MAINTENANCE PERSON AN EXPERT IN SURFACE CLEANING USED IN MAKING THE EXTERIOR SURFACES. IT IS INTENDED TO GIVE THE BUILDING OWNER & HOME-OWNER A GENERAL IDEA AS TO WHAT IS OCCURRING WHEN PRESSURE WASHING MAINTENANCE IS TAKING PLACE.
FIRST material to be discussed will be STUCCO. Stucco contractors build two main types of stucco installs. One being the TRADITIONAL using sand, lime and water. Then second is SYNTHETIC using a multilayer of foam board, coat of the synthetic stucco, fiberglass mesh and then a top coat. (NOTE: if these two methods are used the contractor who is on this project is responsible to protect the glass from stucco splatters and keeping the water off the glass when keeping the stucco wet with water during there process) Traditional & Synthetic Stucco for maintenance we soft wash with filtered water ran thru a Deionization method removing minerals from the water so you do not leave minerals behind on stucco, glass and all other surfaces. You can use a power washer (Hot) or pressure washer (cold) to clean, most cases no need for any chemicals to treat stucco surfaces. If chemicals are needed it is usually added in some instances to remove some rusts or other bad stains.
Some defects or problems already present to be aware of are cracking and flacking traditional stucco do to earthquakes to structures moving, dents and marks in synthetic do to home owners or hired contractors working around home using heavy equipment that may accidentally hit the wall of stucco. Stains that will not be removed are hardwater deposits do from sprinklers which make a white chaulky look on top surface of the stucco. Inexperienced power or pressure washers can damage exterior surfaces of home if they have never been trained or certified by PWNA (Power Washers of North America). This includes using the right tips for the stucco types and filtering the water they use to clean with. Painters and home owners who wash exterior surfaces without filtering or using the right tips can cause these issues. Lines, blowing off paint, make cracking flaking worse, holes, swirl marks from a rotary tip and minerals left behind on surface and glass that cause a white chaulky look and spotting on glass
SECOND material to be discussed will be vinyl. Vinyl maintenance we soft wash with filtered water ran thru a Deionization method removing minerals from the water so you do not leave minerals behind on vinyl, glass and other surfaces. You can use a power washer (Hot) or pressure washer (Cold) to clean and most cases no need for any chemicals to treat vinyl surfaces If chemicals are needed it is usually added in some instances to remove some rusts. Some defects or problems already present to be aware of are holes, buckling, chaulking, mildew-algae. Stains that will not be removed are hardwater deposits do from sprinklers which make a white chaulky look on top surface of the stucco.
THIRD material wood, whether it is Douglas fir, Redwood, Maple, Oak, cedar used for siding, roofs and many parts of the structure are prone to the outside elements.
Earlier-Generation Trex Decking
DIRT AND DEBRIS
Clean deck to remove dirt and debris. Soap and water is all that is needed.
Most colored chalk lines are permanent. For Trex use either baby powder or Irwin Strait-Line®* Dust-Off Marking Chalk available at www.Irwin.com.
The printing on the side of Trex decking boards is required by building codes. With careful installation, most printing can be hidden. Visible printings can be lightened with acetone.
WATER SPOTS, LEAF STAINING AND WOOD TANNINS
Tannin leaching occurs naturally in Trex and all wood-based products. Allow for at least 12 weeks of normal weathering. This process may be hastened through the use of a product containing oxalic or phosphoric acid, commonly known as Deck Brightener. **
ICE AND SNOW
Calcium chloride or rock salt, available in many home centers, will melt ice on Trex decking. Rinse off when first practical. Use caution when removing snow or ice with a snow shovel, and NEVER use a metal snow shovel on a Trex deck. A shovel may scratch the deck, which is not covered under warranty.
SCUFFS AND ABRASIONS
Scuffs and abrasions can fade or disappear naturally after 12-16 weeks of weathering. This can be accelerated with a product containing oxalic or phosphoric acid, also known as Deck Brightener.
RUST STAINS, GROUND-IN DIRT AND GRIME AND PIGMENT STAINING
Use a cleaning product containing oxalic or phosphoric acid base, also known as Deck Brightener, to lighten or remove the rust or dirt. Product may need to sit on stain 10-15 minutes before rinsing. **
Rinse the stain with hot water as soon as possible. Use Pour-N-Restore® ***(www.pour-n-restore.com) as directed for any remaining stain. (Test in a small area first as Pour-N-Restore may remove some of the colorant from the decking surface).
MOLD AND MILDEW
Semi-annual (spring and fall) cleaning of your deck is important to prevent the build-up of pollen and other debris that can support the growth of mold. Refer to Mold Technical Bulletin for specific cleaning recommendations).**
NOTE: Trex Escapes® can be effectively cleaned by using a hose and warm, soapy water with a soft bristle brush.
USING A PRESSURE WASHER
Trex does not recommend the use of a pressure washer. The use of a pressure washer on deck surface could damage the decking surface and will void the warranty with respect to any condition caused by the pressure washing.
Trex does not recommend sanding. Sanding will change the appearance of the surface of Trex material and will void the warranty with respect to any condition caused by such sanding.
Trex decking and railing products should be disposed with normal construction debris or household waste. DO NOT burn Trex products.
* Strait-Line is a registered trademark of Irwin Industrial Tool Company.
** Use of products containing bleach or acid will lighten the surface of Trex. Use in an inconspicuous area to determine whether you like the effect. Neither product will affect the structural integrity of Trex.
*** Pour-N-Restore is a registered trademark of Edgewater Industries.
Note: Trex does not recommend the placement of rubber of vinyl materials such as those found in grill mats, rubber-backed welcome mats, vinyl or PVC potted containers, etc., on the surface of Trex Escapes® for extended periods of time. Over time, additives in the rubber and PVC products have a tendency to migrate from these materials to Trex Escapes, resulting in discoloration of the surface.
Transcend, Enhance, Select
DIRT AND DEBRIS
The affected area should be sprayed off with a hose to remove surface debris. Use warm, soapy water and a soft bristle brush to remove dirt and debris from the embossing pattern.
HARD WATER STAINING
Hard water is water with a high amount of mineral deposits like lime, silica and calcium. When the water dries, deposits are left behind, leaving unsightly spots on surfaces. This is not a defect of Trex products but an issue with the water itself. Generally these deposits can be cleaned with white vinegar on decking surfaces or use of Magic Eraser® on railing surfaces. Rinsing is required so care should be taken to not use hard water for this purpose, and if it must be used, dry with a cloth or use a blower to dry surfaces.
Most colored chalks are permanent and may discolor the surface. Use only Irwin StraitLine®* Dust-Off Marking Chalk (purple), available at Irwin.com
TANNINS DUE TO DEBRIS
Remove all debris from deck using a hose or broom. Once the deck surface is dry, apply a “brightener” ** to the deck as directed by the manufacturer. Deck brighteners contain oxalic acid, which will remove tannins.
ICE AND SNOW
A plastic shovel may be used to remove snow from the deck. Use calcium chloride or rock salt to melt the snow and ice from the deck surface.
All food spills should be removed as soon as possible. The surface must be cleaned within seven days to maintain the stain warranty. To remove, spray off with a hose and use warm, soapy water and a soft bristle brush to remove spills from embossing pattern.
MOLD AND MILDEW
If debris, such as pollen and dirt, is allowed to remain on the deck surface, mold can feed on the biofilm. Using a hose and warm, soapy water with a soft bristle brush is recommended to remove the food source and mold.
USING A PRESSURE WASHER
A pressure washer with no greater than 3100 psi*** that has a fan attachment/adjustment and soap dispenser may be used to remove dirt, concrete dust, or other types of construction dirt. Spray deck with soap, then follow by gently scrubbing each deck board with a soft bristle brush. Spray/rinse each individual deck board using a fan tip no closer than 8″ from the decking surface. RINSE THOROUGHLY. If dirty water from cleaning is left to dry, this will cause a film to remain on the decking surface.
MAINTAINING TRANSCEND AND SELECT RAILING
NEVER use acetone or other solvents on Trex Transcend and Select railing to maintain the beauty of the surface. For color transfer issues (from attachment of baluster spacer), use Mr. Clean®, Magic Eraser® Original or Magic Eraser® Extra Power to help remove this.**** For small surface scratches, marks or scuffs, use Dupli-Color Scratch Seal™ Clear Sealer Pen.*****
TREX AND STATIC ELECTRICITY
While this is not common, static electricity can occur on walking surfaces in dry climates or in areas where dry winds and dust-borne particles lay on the decking surfaces. Static electricity can build up on occupants walking across any composite decking surface, including Trex, then produce a small static shock if they touch a grounded metal surface such as railing, door, etc.
This condition can be decreased greatly with the use of a product call ACL Staticide®. Two products tested were General Purpose Staticide® and Heavy Duty Staticide®. Both are effective in greatly reducing static electricity on Trex decking surfaces. Apply full strength using a mop on a dry decking surface, and allow to dry; no rinsing or diluting needed. Products are non-toxic, non-flammable, non-staining (will not change the color of decking surface), completely biodegradable and safe to use. Product is water-based and may require a second application after rain or other weather conditions. Over a period of time, the effect of static will dissipate naturally on the decking surface.
See link for more information on product:
JOB SITE STORAGE
Store decking on a flat level surface and always use proper supports (dunnage), Do not store directly on the ground. When stacking decking bundles, supports (dunnage) should start approximately 8″ (0.20m) from each end and be spaced approximately 2′ (0.61) on center. In addition supports (dunnage) should line up vertically/perpendicular to the decking product. Adjust support blocks (dunnage) accordingly if bundles are loose. For Select decking, 1″ x 12″ and 1″ x 8″ products, the maximum stack height is 12 bundles. For all other decking products, maximum stack height is 14 bundles (IMPORTANT TO NOTE THAT PROPER DUNNAGE SPACING MUST BE IN PLACE FOR THESE HEIGHTS). When stacking multiple bundles, ensure that dunnage lines up vertically down through each stack. Always cover decking products on site until ready to be installed.

Certain things will be helpful for you to know about the cleaning maintenance system:
First, even if the chemicals are misused the cleaners themselves cannot do damage to the awning. As a chemical manufacturer WINSOL designs chemicals to work safely using high dilution ratios and the label instructions are written accordingly. These ratios are averages for best results. It is our experience, however, these labels are often not read or merely glanced at. Our products, therefore, are designed to be safe even when used improperly. The biggest problem the OTHER inexperienced, companies maintenance technicians will encounter (when improperly using the product) is that improper dilution rations may mean the product may not work as advertised. Cleaners are designed to need a certain mixture of water to work properly.
Second, that in order to assure you that the chemicals cannot due damage to the awning there must be some trade off as to what WINSOL may or may not clean. WINSOL’s awning maintenance cleaners cannot be all things to all fabrics. To insure, that the maintenance person does not damage awning fabrics certain safeguards were built into our line of products. Because DBA THE WINDOW CLEANING SPECIALIST, LLC TECHNICIAN may not know the exact type of fabric being cleaned it is assumed by WINSOL that the fabric in question is an eradicable finish (even though this will not always be the case, of course) this way one will error on the side of safety. However, this will mean that on some vinyl awnings black streaking may not come clean with the first cleaning. Most will fade, however, and more will fade with the second cleaning. It may take a few cleanings, but they will come clean. This is where the tendency to use a stronger cleaner that offers quick results can cause problems. It is best to explain to the awning owner that a proper maintenance program will cure the problem over time and prevent it from reoccurring. Remember, if you are cleaning a SUBWAY awning and your crew makes it into =SUB=WA=Y, it can be a very expensive day. It must also be remembered the environment in which the awning has been placed plays a great part as to the cleaning ease of the awning. If the awning is situated near a bus stop, highway, factory or any place where there is a greater chance of airborne pollution it will be more difficult to clean.
Third, WINSOL’s awning maintenance chemicals cannot repair damaged fabric. Damaged, cracked, ripped, sun-faded or heavily oxidized fabric may require replacement.
Fourth, WINSOL’s line was developed to work with a major vinyl manufacturer’s fabric that is considered the most delicate on the market. WINSOL’s chemicals are sold under private labeling by vinyl manufacturer’s as well as under our own name. This should give you the confidence that our products are safe for any type of fabric you will encounter on the job. It is paramount to remember that if you use untested products on an awning, most fabric manufacturers will not stand behind their warranties. ALL PARTIES MAKE SURE ANY PRODUCTS YOU INTEND TO TRY HAVE BEEN FIELD-TESTED BY THE VINYL MANUFACTURERS AND FIND OUT WHO DID THE TESTING. ASK FOR THE PHONE NUMBERS AND A PERSON YOU CAN TALK TO. REMEMBER ALL PARTIES ARE ULTIMATELY RESPONSIBLE FOR ANY DAMAGE CAUSED BY A PRODUCT SOLD OR USED BY ANY PARTY TO YOU BY ANY UNINFORMED SALESPERSON. Use of the wrong chemical can not only cause loss of ink but may well cause a flaking of the topcoat (this is similar to dandruff of the scalp).
When cleaning an awning these simple steps must be followed to insure both ease of cleaning and the best results for your time and efforts. If you follow these guidelines it will save you time, money and a great deal of anguish.

FREQUENTLY ASKED QUESTIONS ABOUT AWNING CLEANING
- WHY DOES IT MATTER WHAT KIND OF CLEANERS TO USE?
Because of the materials used in the construction of the different fabrics, especially vinyl. Vinyl is a petroleum-based product that in resin form is layered over the scrim (loosely layered woven threads) to form a flexible vinyl fabric. If a degreasing compound is used to clean this type of fabric it can actually strip a layer of vinyl off. You must also be careful to use a cleaner that does not contain a solvent or alcohol. These types of products can actually remove color from eradicable fabric. When cleaning a woven fabric, you must use a chemical that will not promote color bleeding. These types of fabrics are more commonly solution dyed these, days so this is becoming less of a problem.
- WHAT MAKES WINSOL’S PRODUCTS ANY SAFER THAN OTHERS?
WINSOL’s products are designed in conjunction with one of the world’s largest- producers of vinyl fabric. Therefore, our formulations are tested every step of the way to make sure they will not damage fabric even if misused. That is the guarantee we give to all of our customers. WINSOL products are the only ones on the market approved by all of the major manufacturers of awning fabric. Therefore, any work done with our products will not void warrantee’s.
- HOW MANY DIFFERENT TYPES OF FABRIC ARE THERE?
There are basically two types of fabric: woven and vinyl. Within these two groups, However, there are literally thousands of grades, styles and manufacturers.
- IF THERE ARE SO MANY DIFFERENT KINDS OF FABRIC HOW DO I KNOW WHAT WILL HURT THEM AND WHAT WILL NOT?
Because we had the opportunity to work with a fabric manufacturer from the very beginning and we used this experience when designing our entire line of products. WINSOL awning maintenance products are designed to be both safe and effective on even the most delicate fabrics. We will guarantee the customer that they will not damage any fabric, even if misused.
- DO I NEED TO BE CAREFUL ABOUT THE TYPE OF EQUIPMENT I USE?
Yes, it is vitally important that you are not too aggressive on vinyl or woven fabrics. On vinyl the danger is scratching the surface. This will dull the finish and possibly allow moisture to penetrate to the scrim and cause mildew to grow under the vinyl coating. If this occurs there is nothing that can be done to remove it. On woven fabric the danger is abrading or “fuzzing” the surface. This will give the awning a fuzzy look when it is dry and shorten the life of the fabric.
- WHAT SORT OF EQUIPMENT WILL WE DBA THE WINDOW CLEANING SPECIALISTS, LLC BE USING?
To get started what we use is a ladder, bucket, source of water and a brush or awning sponge. The brush should be about the stiffness of a hog’s hair brush. The bristles should be relatively short, around 2″ in length. If the bristles get any longer they have a tendency to lay flat and this will inhibit your scrubbing effectiveness. For applying the awning armor the most effective way is with a pole, window washers T-bar and a scrub sleeve or towel fastened. This will give us a wide path of coverage and a soft applicator. We can go from a bucket and brush to a pump sprayer and even a boom truck.
- CAN YOU USE A PRESSURE WASHER TO CLEAN AN AWNING?
Absolutely not! Pressure washing equipment often cannot be adjusted down enough to provide a safe pressure for awnings. It is possible to split seams, stretch the VINYL itself, force dirt deep into the vinyl, blow off letters and graphics and a host of other problems. Damage cause by pressure washing will not be covered by the manufacturers-warranties.
- HOW DOES DBA THE WINDOW CLEANING SPECIALISTS, LLC CLEAN A VINYL AWNING?
There are two types of cleaning: maintenance and restorative. Maintenance cleaning can be done with WINSOL’s AWNING CLEANER AND PROTECTANT. This is a one step process that is effective on new vinyl awnings that are cleaned within about 3 months of installation or on awnings that have already been restored and are re-cleaned every 2-3 months. Restorative cleaning is a two-step process. It is performed with WINSOL DEEP CLEAN as the first step and followed up with WINSOL AWNING ARMOR or XTRA SHINE. Restorative cleaning is necessary whenever an awning is badly soiled and neglected. This will likely be the bulk of your cleaning, especially when you first start and don’t have clients on a cleaning schedule. The cleaning process is the same for both. Start by rinsing the awning down. This will remove loose soil and debris. Next, using the appropriate cleaner (mixed following the label instructions) scrub an area no larger than you can keep wet until you are ready to rinse. It is important to clean from the bottom up to avoid clean streaks. When you have thoroughly scrubbed an area, rinse and move on to the next section. If you are doing a maintenance cleaning rinse once more and you are done. If you are doing a restorative or heavy cleaning proceed to the second step the application of AWNING ARMOR or XTRA SHINE. The awning armor must be wiped on using a soft applicator. It is not necessary to perform any rubbing or buffing though. Let the sealer soak into the fabric and you are done.
- WHAT IS PLASTICIZER MIGRATION?
Plasticizer migration is the natural “off gassing” or drying of vinyl and plastics. This process cannot be stopped but it can be slowed down. The more slowly an awning loses its plasticizers the longer it will last and the better it will look. That is why it is important to replace some of the plasticizers after each cleaning. This can be done by the use of the one step AWNING CLEANER AND PROTECTANT or through an application of AWNING ARMOR or XTRA SHINE.
- DO I HAVE TO USE ONE OF THE VINYL SEALERS EVERY TIME I USE THE DEEP CLEAN OR CAN I USE AWNING CLEANER AND PROTECTANT?
Yes, you should use AWNING ARMOR or XTRA SHINE every time you use DEEP CLEAN. The use of AWNING CLEANER AND PROTECTANT will not properly seal the fabric after the use of DEEP CLEAN.
- WILL THE DEEP CLEAN ALWAYS REMOVE ALL THE STREAKS?
No, sometimes awnings have been neglected to the extent that they cannot safely be completely cleaned the first time. It also depends greatly on the grade of the fabric and the environment to which it was exposed. Most of the time an awning will come completely clean with its second scheduled cleaning. If you have cleaned an awning that will not release all of its streaks go ahead and treat it with AWNING ARMOR or XTRA SHINE. The penetration of our sealers often, lift dirt to the surface as they hydrate the fabric and will allow you to clean it the next time.
- DOES WINSOL HAVE ANYTHING THAT WILL GET STREAKS OUT THE FIRST TIME, EVERY TIME?
A qualified yes. We have cleaning products that we manufacture for other markets that will remove the black streaks with a single cleaning. If they damage the awning in the process, however, we are not really helping you. The DEEP CLEAN is generally as aggressive as you wish to get. A more aggressive cleaner or application system can potentially damage the awning and leave you to foot the replacement cost. When dealing with mold, algae or other growth in woven fabrics the manufacturers recommend a mixture of 4 ounces of laundry bleach mixed with one gallon of water as a pre-spray to kill any growths in the awning.
- DO I USE AWNING ARMOR OR XTRA SHINE ON FABRIC AWNINGS ALSO?
No, fabric awnings do not need plasticizer replacement. What is required for fabric awnings is the use of a waterproofing sealer. We at WINSOL, as well as the fabric manufactures, recommend a non-silicone, air-drying, fluorocarbon based waterproofer. WINSOL AWNING GUARD 690+ is the product of choice for this application. It is best to waterproof fabric awnings annually.
USE AND APPLICATION OF WINSOL AWNING PRODUCTS
There are two conditions to consider when cleaning awnings. First, are awnings that are severely soiled or neglected. The second is an awning that is only slightly soiled and is in generally good condition. You will be able to tell the difference immediately. If an awning appears to be only lightly soiled yet does not clean easily with WINSOL CLEANER AND PROTECTANT, stop and follow the directions for heavily soiled or neglected awnings.
- Light soil and general maintenance product.
Use WINSOL CLEANER AND PROTECTANT.
Tucker awning pole or equivalent, or hand tools. For hand washing a moderately firm brush (generally nylon, are the best), 3M pads (white or yellow), natural sponges or a drywall sponge and a bucket. Dilution for hand cleaning is 1:16. Always clean from the bottom to top to avoid streaking. Scrub the surface firmly and evenly (approx. a 6×10 foot area and then rinse thoroughly as you go to eliminate dried soap scum. If additional suppleness or shine is desired or required AWNING ARMOR or XTRA SHINE may be applied.
2 Heavy soiling or neglected awning maintenance
Use WINSOL DEEP CLEAN AND WINSOL AWNING ARMOR or XTRA SHINE.
Cleaning tools will be the same as described in NO. 1 above. AWNING ARMOR and XTRA SHINE are best applied with a sprayer and spread with a cotton towel, window scrub sleeve or the like.
Dilute the DEEP CLEAN as per label instructions (normally 8 ounces to a gallon of water). Cleaning is performed as described above. Dilute AWNING ARMOR or XTRA SHINE 1:1 before applying. Spray an area that you can smooth out before it dries (drying time will vary with the weather). The awning need not be completely dry from, it’s rinsing as both sealers are water-soluble. Spread evenly using a circular motion to avoid streaking and allow to dry. Reapply as needed and avoid dripping.
Whether the awning is natural or man-made fiber does not change your choice of chemicals or tools. There are two conditions to consider when cleaning awnings. First, are awnings that are severely soiled or neglected. The second is an awning that is only slightly soiled and is in generally good condition. You will be able to tell the difference immediately. If an awning appears to be only lightly soiled yet does not clean easily with WINSOL CLEANER AND PROTECTANT, stop and follow the directions for heavily soiled or neglected awnings. Except for Lichen. Lichen needs more then one time to restore awning back to its original state without a use of a pressure washer to do this.
WINSOL DEEP CLEAN AND WINSOL AWNING GUARD 690+
You will use the same cleaning tools and techniques described above but fabric awnings usually take more hard work, time and cleaner than smooth vinyl as soil and pollutants are free to enter the weave of the fabric if it has not been properly waterproofed. AWNING GUARD 690+ is applied undiluted using a pump-up sprayer and a wide fan tip using overlapping passes to assure even distribution. Properly applied 690+ will prevent soil and moisture from penetrating the fabric weave and will make subsequent cleanings faster and easier.
