Decking, Railing & More

CARE & CLEANING FOR DECKING AND RAILING

Decking: Cleaning do’s and don’ts

To prepare for cleaning current TimberTech Composite or Advanced PVC Decking collections, you’ll need water for rinsing (hose or power washer), the recommended brush for your decking with an extension handle, and TimberTech DeckCleaner™. For specialty decking products, including ReliaBoard, TwinFinish, Earthwood, Floorizon, and DockSider, see the Specialty Decking section below.

DO clean in small, manageable areas, rinsing thoroughly before moving on to the next section.
DON’T let the cleaner dry on the surface—it will cause a white surface film that can be difficult to clean off.
DO avoid getting TimberTech DeckCleaner on other surfaces, including glass, stainless steel, painted surfaces, plants, and vegetation. Thoroughly rinse surfaces immediately upon contact.
DON’T clean your deck in direct sunlight as the heat may cause the surface to dry before you’ve rinsed the cleaner away.
DO use the recommended brush for your TimberTech decking.
DON’T use a stiff, natural fiber deck brush on TimberTech Composite Decking collections, as it can dull the surface.
DO rinse decking thoroughly. A garden hosed is all that’s required, but, if you like, you can use a power washer for rinsing only. Use a fan tip nozzle and a maximum pressure of 1,500 psi and be sure to take proper safety precautions.

Specialty TimberTech Decking: Cleaning guidelines

Because our discontinued collections—ReliaBoard, TwinFinish, Earthwood, Floorizon, and DockSider—are un-capped composite, their cleaning instructions are NOT the same as TimberTech’s current Composite and Advanced PVC Decking collections. These recommended products have been tested to be compatible with our specialty and historic collections to make care and cleaning easier.

Railing: Cleaning do’s and don’ts

The instructions and frequency for cleaning your TimberTech Railing can depend on both the type of railing you have and where you live.

Composite and Aluminum Railing

To keep it looking its best, TimberTech Composite and Aluminum Railing should be cleaned at least once per year (within 12 months of installation) if the deck is located more than one mile from the seashore. For decks located less than one mile from the seashore,3 cleaning should happen twice a year (beginning six months after installation).

DO use a soft wiping cloth and clean water for rinsing.

DO clean with warm water and a nonabrasive, pH neutral (pH 5 to 8) detergent solution—TimberTech Composite Railing can also be cleaned with properly diluted TimberTech DeckCleaner.

DO sparingly use stronger domestic products—such as alcohol, mineral spirits, or bleach diluted to five percent (5%)—if atmospheric pollution has resulted in stains or heavy soiling of the coating. Wipe the area with a soft cloth, then allow to dry.

DO protect your decking with plastic before using stronger cleaning agents, as they may cause discoloration.

DON’T use abrasive cleaners, polish, or solvents—such as thinners or solutions containing chlorinated hydrocarbons or ketones.

DON’T leave protective tapes (used during installation) in contact with the railing surface for more than one month.

PVC Railing

To keep TimberTech PVC railing looking beautiful, it should be cleaned at least twice a year.

DO clean with TimberTech DeckCleaner to prevent dirt buildup and possible staining.

DO clean any exposed stainless steel or powder-coated hardware as well to minimize the effects of corrosion over time.

DO use, in addition to TimberTech DeckCleaner, the following cleaning products for periodic wipe-downs, more stubborn stains, or mold/mildew on unpainted PVC railing:

  • Miracle Mist (stains, mold, mildew)
  • Fantastik Oxy Power Multi-Purpose Cleaner® (stains, mold, mildew)
  • Clorox Clean-Up® (stains, mold, mildew)
  • Fantastik All-Purpose®
  • Spic & Span Cinch®
  • 409 Glass and Surface Cleaner®

DO protect your deck surface under the cleaning area to reduce the risk of discoloring the surface. You can pre-wet the decking and rinse often while cleaning the railing, or cover the area with plastic and remove it when cleaning is done.

DON’T leave cleaning solutions on railing components for an extended period of time—they should be applied and immediately wiped dry.

DON’T use harsh cleaners with glycol ethers or ethanol type solvents and/or isopropyl alcohol. Examples of these harmful cleaners are Goof Off®, Wal-Mart Great Value All Purpose Cleaner® (glycol ether), 409 General Purpose® (2-Butoxyethanol) and Greased Lightning® (glycol ether), citrus cleaners, abrasive cleaners, and solvents such as acetone, paint remover, and lacquer.

For TimberTech’s specialty or discontinued composite products (ReliaBoard, TwinFinish, Earthwood, Floorizon, and DockSider), here are some additional watch-outs:

2. These cleaners should not be used on TimberTech’s current Composite or Advanced PVC Decking.
