Kleen-Strip is the brand I posted. think it can be bought at most hardware stores. Auto supplies sell these products especially ones thad deal with automotive paints. various Mfg make it. It is around $20 a gallon and if you buy PPG is costs more.
When Iam washing greasy parts in gas, I`ll use this for a final rinse to really get the oil residue off. using it on a paint surface won`t lift or wrinkle it like using brake cleaner, as this stuff is used in painting body panels before sanding or final paint. good stuff.

I have a gallon of marine Clean too, I know this was the original question.
There are a lot of good products out there that will do the same resullts>
