It's some good stuff, for sure.I thought i was the only one who knew about Sonax. haha Good to know someone else appreciates German engineering
Windex is actually quite acidic, and can, in some cases, harm the wheels.windex works wonders for getting the chrome clean and shiny (need a protectant after though), you can use blue magic metal polish as well. i used it on my polished aluminum wheels and my chrome wheels and never had a problem. plus its cheap lol. the nice thing about it is it leaves a "film" that beads water really well.
