I just bought a new product I found at my local (not a big chain) parts store called Wizards black renew. They claim it will remove wax residue too. Initial tests (just a bit applied w/ my finger) look good, we'll see how it does when it gets warm enough to do the whole car.
Anyone here have any experience w/ this brand?
After I get it applied & it's been rained on a couple times, I'll post results
