How to Clean Paint From Trex Decking
Proper cleaning techniques remove paint from Trex decking. (deck image by Albert Lozano from

Trex is a composite material widely used for outdoor projects like decks and fencing. Unlike wood, which must be stained and sealed and is subject to wear and weathering, Trex is a long-lasting material that holds up well to an outdoor environment. When paint drips occur, however, the deck cannot be sanded and refinished. Instead, other measures must be used to clean paint from Trex decking.

Skill level:

Things you need

  • Warm, soapy water
  • Hose
  • White spirit
  • Soft-bristled cleaning brush

  1. 1

    Clean the surface dirt of the Trex deck with warm, soapy water. Rinse thoroughly with a hose.

  2. 2

    Test the white spirit on an unobtrusive area of the deck to ensure that it does not damage or discolour the surface.

  3. 3

    Apply the white spirit to the paint stains, allowing the product to sit on the stain until it softens. This usually takes five to 10 minutes.

  4. 4

    Scrub the paint stains gently with the soft-bristled brush, removing the loose particles of paint. Do not scrub hard or you may mar the surface.

  5. 5

    Apply the warm, soapy water directly to the stained area to remove any residual grease from the surface of the deck.

  6. 6

    Rinse the deck with the hose.

  7. 7

    Repeat this process until the paint stain is no longer visible.

Tips and warnings

  • Paint stains from oil paints may react differently than those caused by latex paint.
  • Check all cleaning products and methods used to ensure that they will not void your warranty.
  • Trex decking may be painted in the event that the paint stain cannot be entirely removed.
  • Never sand your Trex decking.
  • Do not use cleaning products designed for real wood decking, as they can damage your Trex deck.
