Most people I know that use 303,dilute it with water,since it is not cheap.I've used it,but with my dark green color,there are streaks if I don't wipe it good enough.
I was told that sno-bowl works good to clean your teak deck.I tried it once,& what do ya know...it does!!Scrub it in with a firm bristle brush(not steel),then spray it off.
