Someone  laid my new vinyl gaucho cushion on an old piece of wood that had the dreaded silver sludge on it. It apparently spent some time there because when he finished the frame and put the cushions back in, there is a nasty brownish gray sludge smeared on my couch. I'm worried about damaging the finish trying to get it off. Of course regular old soap and water didn't do much. I tested the citrus orange cleaner - no go, takes off the finish Does anyone have any other ideas? |

That's a tough one on vinyl. Things made these days aren't as sturdy. I'd go to a dry cleaning place and see what they say. You might be able to test a tiny corner somewhere.
Silver Sludge is asphalt or tar based. It does turn nasty brown if you use chemicals on it. Just a stain you might try toothpaste and a brush?? Another try might be denatured alcohol. Or charcoal lighter fluid. If citrus messed with the finish, BE CAREFUL.
Good luck and post a picture and results.

If the stain is flat and not in a really prominent place, you might want to try leather dye on it, or even a flexible acrylic fabric paint.

Brake and parts cleaner is My go to for most any cleaning problems, especially asphalt based smudges. Try some on a rag, on an out of the sight place to be sure it will not discolor the vinyl.
I use the B&P cleaner on all sorts of vinyl type materials on My truck, the wifeys car and anything else that needs cleaning, even the motorcycle seat.

Finally uncovered the vette and had to face the problem I'd been avoiding because I was so worried about ruining the cover. mrmarty51 You're a genius!! I tested the brake cleaner on a scrap piece and it didn't damage the vinyl at all - may have made it just a bit shinier. It cleaned up the smudged part immediately which was the biggest part of it. It didn't clean the edges where most of the pressure from the board were, but it is such an improvement and the vinyl is dark so it's not nearly as noticeable. Thank you so much for your suggestion, I never would have tried something like that. I may try a couple of the other suggestions for those last spots.

Lacquer thinner is quite a bit harsher than B&P cleaner. It is about the same stuff as carburetor and choke cleaner. You might very very carefull try a very small spot and see if that stuff affects the material, and, if it does not make the material into a gooey mess then try some of it.
