Thanks guys for the tips. I have actually had great luck with my small SunJoe electric pressure washer. With the 15* tip, it makes short work of bringing them back to gleaming white with no detergents needed for those results. Only tap water. I was just hoping that there was a way to repel the staining since sometimes, I leave the boat at our local yacht club for a couple weeks at times to avoid repetitious rig/re-rig, mast/de-masting, trailering, etc. that comes along with bringing it home after each use. I'm guessing by your responses that it might be easier to leave my pressure washer at the club during those times? I'm probably being overly picky about aesthetics but I worry about it becoming permanently brown lol. I liken it to those old denture commercials where they dip the white porcelain into the tea and instantly they come out with a definitive stain line.
