How to Remove Scratches on Trex Decking
- 1). Spray the affected area with your garden hose to remove any dirt or debris from inside the scratches. Use a soft-bristled brush to remove dirt from deep scratches.
- 2). Put on protective gear such as goggles and work gloves before you mix the oxalic or phosphoric acid-containing cleanser. Mix the cleanser according to the package instructions.
- 3). Apply the cleanser to the Trex deck, concentrating on the scratched area. Agitate the solution with a soft-bristled brush and allow the solution to work for a few minutes.
- 4). Rinse the area thoroughly with fresh water.
