I hope this posts reaches the masses. Any object on this planet that is outside will eventually need cleaning. Fences, decks, house siding, concrete, wood, vinyl siding, etc . Besides dirt, usually it will be mildew that gets on it.
Way too often I hear customers mention a salesperson of some kind that told them “fill in the blank material does not need cleaning ever”. I have heard it about vinyl siding, vinyl decking, trex, etc. The homeowners is being lied to point blank. Some materials need less maintenance than others but they all get dirty.
Pressure washing yearly or at least every 18 months is the best bet for keeping your structures looking their best. Of course different materials need different care… see comment from Trex Rep.
