alas, when other family members invite guests they do not specify shoe soles. so now for our hospitality , we have black scuff marks at various places on deck. (the black marks are not as bad as the lady who came on boat with fresh bright red toenail polish that was n't dry and left streaks. she was upset that she'd messed up her pedi-cure. i was upset the spouse had invited her in the 1st place...) I use FSR and that's a pain. any other suggestions from the group ?

If I demand that the USCG take off their boots if they wish to board my vessel, why would I allow guests to do so? I even asked an owner (unknown to me that he was the owner at the time) to remove his shoes when boarding a boat I had delivered, and it got me a great full-time job running his schooner in the Med and Caribbean!
An ounce of prevention is worth a pound of cure, right?

Another vote for acetone.... works well on rubber, grease type marks. For organic, living, ex living, such as algae/mold/pond scum etc., use an acid based cleaner... basic toilet bowl cleaner from smart & final is cheap and effective.

Wouldn't those take the wax or polish off the gel coat?

Another vote for Magic Eraser. I think you may have to touch up the wax though.

Acetone, magic eraser and dawn dish soap will take the wax off.
"No black sole shoes" is the best solution. Barring that, elbow grease and a damp, inside out sock works and won't damage the wax.

It might be easier to simply reapply some wax to the area in question.... Anyway, if you're waxing/polishing your topsides yearly you can wait to clean of the marks, or wait to re wax... Personally, my boat can live without a coat of wax of a few months.... more than I can tolerate the scuff marks. If it's on the non skid.... who waxes that area anyway?

Wait... are you talking about top sides (hull above the waterline) or decks? Are people walking on your hull? I don’t think so.
Do people wax their decks? That sounds slippery. Besides, wax wouldn’t work too well in non-skid.

I think a polished and waxed deck make it easier to clean up scuff marks. The gelcoat isn't as porous. I try to remember to touch up areas that I have scrubbed on with chemicals. And I'm one of those who waxes the non-skid areas. I use Woody Wax for non-skid.
