I agree The softscrub works wonders. Also a product that is safe on art and
tough on
dirt is GREASED LIGHTNING. I think the purple stuff is the same but not as
strong.
it melts nicotene and grime on the spot. After the CP is clean, i like to add
a rub
on silicone and buff the vinyl to get the wet look and protect from cracking.
It works great on dingy coin doors, leaves them black forever. Try it.
