Spot Stains
Many stains can be cleaned with soap and water. If the
stains have set, the following cleaners have been found to
remove or reduce the stains. Always follow the manufacturer’s
instructions to achieve maximum results. Areas cleaned may
lighten; this will require 8-10 weeks exposure to the sun to
match the remaining product.

• Simple Green
Spray Paint

Oil, Grease

Scratches, Nicks, Cuts and Grooves
TwinFinish, ReliaBoard, and DockSider planks and
TwinFascia (in Cedar, Grey and Redwood):
Scratches, nicks, cuts and grooves can be eliminated by using
a wire brush. Brush in the direction of the grain of the product.
The brushed area will weather back in approximately 8-10 weeks.
Dirt, Grime, Tannin and Mildew Stains
TimberTech products are formulated to inhibit mildew growth
and minimize staining. Rinse off your TimberTech products
periodically with a hose. Even if it appears clean, it is important
to prevent build-up of pollen/debris. Mildew stains may occur
where moisture, pollens, and/or dirt are present. Mildew needs
a food source to grow, which can be grass, pollens, dirt, debris,
wood and wood resins.
Maintaining a clean, dry surface is the best method for
combating mildew. Ensure that water drains effectively from
your deck. For TimberTech Earthwood Evolutions, TwinFinish,
DockSider and ReliaBoard, be sure that gaps exist between
planks to allow for drainage.
Like any wood-based product, TimberTech’s wood-plastic
composite products (ReliaBoard, TwinFinish, and DockSider)
may experience a naturally occurring process called Extractive
Bleeding. This process may cause a temporary discoloration
that will weather away. In most cases the weathering process
takes 8-10 weeks but could vary depending on location and
specific product application such as a covered porch.
If the stains have set on TwinFinish, ReliaBoard, or DockSider
planks, you may want to use fine sandpaper and sand lightly
followed by a wire brush to re-grain the decking. Always follow
the wood grain finish of the plank. The sanded area will weather
back in approximately 8-10 weeks but can vary depending on
location and specific application.
