I put about a half of a cup of Tide powder in the bilge and a little water and go boating. When i get home hose it out and it's clean. An old jet ski mechanic told me this. Works great

Steam genie pressure washer and a little degreaser after to get the film off, paint if you want or have to...

I just did today, Zep purple stuff undiluted, used injection tube from pressure washer soaped down heavy let stand for about 10 minutes,(did this 3X), then flushed & drained. third time though I soaped and was letting work and then added outdoor Bleach the thick stuff from Home depot, let that stand about 15 minutes then flushed/drain x 2

all black stuff are grey and all red items are pink....................... worked too good


Just kidding, worked great
