I verified with Trex that it isn't their product. House built in 2006, we are the 3rd owners. Owners number 2 likely did not do maintenance on deck, rails, steps. I am looking to clean and hopefully restore product. (If it is revivable, can/should I stain it in some fashion?) The posts appear to be painted wood in poor shape, can I use products recommended on both the composite and the wood. How low or high should I develop expectations?
Just pressure wash it with a deck cleaner to remove the algae and mildew. You can apply a solid stain to the railings. Leave the composite unstained.
Thank you Deck Stain Help. May I ask if there is a particular deck cleaner you would recommend? The Trex people proposed Olympic Brightener and Wash or vinegar. Same question for recommendations on the solid stain. Thank you very much.
The Restore A Deck Deck Cleaner or Defy Wood Cleaner. See here for solid stains:
