I used a high-power washer immediately after pulling it out. It
probably would work now if you can borrow, rent or find one to
use. Then the ON-OFF where the stain will show. Good wand car
wash might even work, if it's not too bad.
BTW, found two gouges in gelcoat, one behind keel and one
forward of the rudder that might have caused water to get inside
gelcoat. Most of the mini-blisters disappeared. None were bad
abyway. After 7 months of drying out I patched the gelcoat.
Most of the time I trailer so I'm not going to worry about it
for now.
