I've got stock 2011 s63 20 inch

I keep the rims clean. Usually twice a week and only have to use stoner glass cleaner and stuff comes right off. This past week something got on my front rim and I can't get it off.
Its like its baked on after only 2 days. I'm thinking its got something to do with the fact all the streets by me are being repaved.

I saw this "iron x," product online. Looks like a winner, but ive got no clue.

Anyone have advice on how best to clean the rim?

Iron X is a good product but there are other less expensive products you could try first i.e. Sonax FE, or Sonax Plus.

 

Thanks- will check it out
