How to Clean My Salt Lake TimberTech Low-Maintenance Deck

Spring cleaning time is here. Do you know how to clean your low-maintenance deck?

If you opted for a Salt Lake low-maintenance deck, the low-maintenance lifestyle was quite likely a contributing factor to your choice. You may notice we call it “low-maintenance” decking despite the fact that there is zero required sanding, pressure washing, staining, or sealing. The reason for the distinction is due to the recommendation that you occasionally clean your TimberTech deck to keep it looking its best. Often people ask us how to clean Salt Lake low-maintenance decking for fear of damaging the finish or otherwise. Here is what you need to know before you clean your composite deck.

How to clean my Salt Lake TimberTech Deck

Before You Begin

First: Know what type of decking you have. Composite deck cleaners are for composite decking boards. Most new low-maintenance decks are actually capped composite and require a different cleaner. Don’t use Corte Clean®, Thompson’s® Water Seal® — Oxy Action, Olympic® Deck Cleaner, or other “composite” deck cleaners on TimberTech Terrain, Tropical, or Legacy Collections. If we built your deck and you are not sure what you have, call us. For capped composite and fully synthetic PVC decking you can use a mild liquid soap and water. Dawn Ultra® offers great results.

Second: Make sure you have the correct brush if you’ll be doing some scrubbing. Natural fiber brushes can dull the surface. We recommend a medium plastic bristle deck brush or Quickie® Professional Pool and Deck Scrub.

How to Clean Your Low-Maintenance Deck

Capped Composite & PVC such as TimberTech Terrain, Tropical, or Legacy Collections:

Work in small areas to avoid letting the soap dry on the deck surface. It’s best to avoid cleaning in direct sunlight, especially on a hot day.

  • Cover the area with a mild liquid soap-and-water mixture.
  • Allow it to soak for about 30-60 seconds. Do NOT let the cleanser dry.
  • Scrub area with the recommended brush type, first with the grain, then against the grain.
  • Do NOT let the area dry before rinsing, as dirt and soap residue will dry into the surface texture.
  • Thoroughly rinse with clean water immediately after scrubbing.
  • Allow the cleaned area to air dry completely.

Composite Decking such as TimberTech TwinFinish, ReliaBoard, or DockSider Collections:

TimberTech products can be power washed at a maximum of 1500 psi. Be sure to spray in the direction of the grain. You can use any of the recommended composite deck cleaners on your composite decking. You’ll find them at any hardware or big box home improvement store: Wash Safe Spray and Clean Composite Deck Cleaner, Resist Mist Composite Deck Cleaner, Corte Clean, Super Deck Composite Deck Cleaner, Thompson’s Water Seal – Oxy Action.

Once you choose a cleanser follow the instructions on the bottle carefully.
