Through regular use and atmospheric conditions, GeoDeck may become dirty and require light cleaning to keep it looking fresh, as well as to allow Tongue & Groove boards to drain properly.
GeoDeck is easy to clean. Most stains can be removed with a general-purpose household cleaner and/or degreaser according to manufacturers instructions. Concentrated dish soap or laundry detergent works well on most stains. Remember that fresh stains are usually easier to remove than ones that are allowed to set.

Periodic cleaning with a pressure washer will help keep GeoDeck looking it's best. Proper use is very important, so please follow all manufacturer instructions and use proper safety precautions when operating a power washer. The power washing unit should be set at a lower pressure setting (500-800 psi maximum), and use a fan tip nozzle. Spray should be consistent with the “grain” of the product. To prevent damage to the boards, be careful to stay a minimum of 12” off the surface and do not let the spray sit idle too long.
Simply use a stainless steel wire brush to remove scratches. A few strokes along the grain will most likely refresh the GeoDeck board.
For oily stains such as gasoline, butter, mayonnaise, etc., use concentrated dish soap or laundry detergent along with a plastic bristled scrub brush.
Microbial stains, such as algae and black mold, do not damage GeoDeck boards. For the most part, algae and black mold sit on the surface and consume pollen without degrading the board. These types of stains can be removed by the use of a pressure washer, plastic bristled scrub brush, and cleaners designed to remove mold and mildew.
