Try Sno-bowl toilet bowl cleaner, This works great on removing rust
stains from fiberglass. I would wash the deck with a soap cleaner first
however. Apply the Sno-Bowl let stand for a few minutes, then scrub
with a brush and rinsh well.
Try to avoid getting this on aluminum. I will also work on Stainless.
But you should polish the stainless after to prevent oxidation.

Hi Sailors,
I just had my decks emroned with a sand mix for no-skid areas and the
boat look great, however when a worker drills metal somewhere the tiny
shavings blow onto the decks and ultimatly become these hard to clean
rust dots...

Any luck with non skid deck cleaning materials??
