I used an aerosol spray Goof-Off to clean my white walls today. Worked really really well. The smell though....made me wonder if this stuff can damage the tire. The label in the can indicated that it would be safe to use. Anyone else use it?
An old mechanic showed me his secret formula with household items. He would spray the white walls or white lettering with Easy Off Oven cleaner, Wait for a few minutes, then hit it with an SOS pad, hose off. Man, that works and doesn't cost much.
I used brake cleaner and scotch brite or magic eraser when I had WWW.
Worked good still had to scrub some. Its best to stay on top of it and not let it get real bad. Never say any bad results bit I always wondered what it was doing to the WWW.
