How often do you do it then? Sounds like not every year. Mine I
pressure washed last year and it was beautiful, but in about 2 weeks
it was graying again, because I didn't put anything down. (New to
decks, you know!)

My application is outdoor furniture. I've done it every two years because
a. I still have plenty of it
b. it is simple enough to do

I'd think every three or so would be about right.
