Here's what I 've been wanting for over a year and found at Hershey. Now that I have them, what is the best thing with which to clean them?
I use a liquid spray, Westley's Bleche white.
Make sure you don't allow that stuff to dry on the tires.
GOJO with Pumice. Works like a champ.
Ditto on the above!......
Finally! Nice score Mike!
I've only used Wesley's Bleche White on modern whitewalls. After I apply it and let it soak a little bit, I scrub the whitewall with a brass bristle tire brush that can purchased at an auto parts store.
Bleche White works by dissolving a very thin layer of rubber that is scrubbed and rinsed off.
Call me crazy, but those "Magic Eraser" sponges work amazingly on everything I have used them on. Kitchen counter stains, boat cushion stains, etc. You may go through a box of the things, but I'd give it a shot.
