When I cleaned my upholstery for the first time in my 91 I had, nothing would touch it and I mean nothing.
I ended up using magic erasers, black streak remover for an RV and lots of water. Never letting it sit on the material.
Then a lot of 303 after that, actually rubbing it into the upholstery with my hands prior to wiping it
I live in my own little world. But it's OK - They know me here
