I gave the polished aluminium alloy wheels on my car a long overdue clean and the alloy wheel cleaner I used (non acidic) didn't shift the baked on brake dust residue on the sides (shown by pink line), despite using a brush. I've tried several ways without satisfaction. Bathroom cleaning paste got it off easily enough, but dulled the finish. Autosol metal polish only slightly removes it but leaves the finish to the desired shine.
I tried fast acting oven cleaner, but again it left the finish even duller than the bathroom cleaner (pointed out by white line).
Any suggestions would be appreciated. I even tried my hand held steam cleaner. No effect.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
