If you have white wall tires you've gotta try armorall wheel and tire cleaner
I had white walls on the car and tried everything but nothing even came close.
Also cleans those brake dust covered aluminum front wheels on your car or truck.
I swear it's almost magic....... almost
Oh yeah. Remember the old Herbal Essence commercials? The ones with the very enthusiastic ladies washing their hair? "Yes, yes, YES!" Well, you'd love the wet look that tire gel gives ya
I don't use anything on my tires but soapy water (generic dish liquid soap 99cts.) and a scrub brush. Cheap pot scrubbing pads work good on the rims brake surface too. Get all that rubber out and they are like new.
