F4ck all that, just use Armor all Tire Foam, best shit ever, spray on liberally and let the foam dissolve and viola! Instant shine!
Same goes for, armor all "Protectant wipes" For the insides of cars. What we used at the dealership cleaning cars.
Whitewall cleaner is fine if you get it on your rims, just wash off immediately with clean water. If your rims are aluminum don't lets it sit on them for more than a minute!
If you have white letters, get a bucket, put 50/50 mix of water and white wall cleaner, find a smooth rock, and scrub your letters hard a few times, and They'll look brand new! Used to work at les schwab.....
