As many of you know, I am not a fan of strong chemical wheel cleaners. I use them as needed, but once my wheels are clean, I protect them with a sealant, and just wash them with car wash and a sponge every week. Over time, some brake dust particles become embedded in the clearcoat of the wheel, and sometimes it takes something a bit stronger than clay to remove them.
I tried MOTHER'S Clear Coat Wheel Polish on my wheels this weekend. It appears to be a very mild abrasive (which I was looking for), and took more elbow grease than a chemical cleaner, but the results were very pleasing. I used a foam pad cut in half for application, and the product was very easy to work into wheel surface. After a few seconds of rubbing, it buffed off very easy and clean with a cotton towel. It removed the embedded particles of brake dust, as well as some surface scratches on the wheels from road debris and rocks. It left the wheels very glossy and smooth, with a perfect "like new" finish.
I followed up with a spray of car wash in a squirt bottle and a hose rinse, and then applied a sealant to the wheels. I plan to do this polish/sealant process every few months as needed on the wheels. I give Mother's clear coat wheel polish a thumbs up, and feel I had better results with it than using a harsh chemical wheel cleaner. If your wheels are a bit neglected though, I would use something a little more aggressive.
