If the job is not too big try denture tooth paste with a tooth brush.
If this is not enough try using CLR. Apply the CLR as directed and rinse it
after.
I suggest that you try the these on test pieces or an area out of the view
before doing the overall job.
Do not rub or bush too hard because you may expose the no-skid sand mixture.
BTW. Here we use a walnut grinded mixture instead of pure sand.

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??
