WowContrary to popular belief, Wheel Brightener isn’t all that effective in cases where you’re dealing with years and years of baked on brake dust. It excels as a maintenance wheel cleaner, where if used with a power washer can be used as a touchless way to clean most OEM wheels.
But when up against what OP is dealing with you better be ready to put in some work as far as the brushing because you’re going to be there for a while and probably won’t get it completely clean.
When dealing with the super max caked & baked wheels you need something like Brown Royal or even that Auto Fanatic wheel cleaner used at maximum strength [since he claims it’s near or as effective as Brown Royal... I’d have to see it to believe it]
-Almost 20yrs. of baked on brake dust.

Even with full access, Wheel Brightener couldn’t get it fully clean. Try to do this with the wheel on the car and you’ll be scrubbing for maybe an hour or more.

Completely clean in 1 quick scrub & rinse.

And if Wheel Brightener can’t do it, that means there’s no way the Sonax Wheel Cleaner can. There’s videos proving it can’t handle real baked on brake dust.
@OP. If you want to get an idea of what Wheel Brightener can do, pick up a bottle of Meguiars Hot Wheels Chrome Wheel Cleaner. It’s basically the OTC version of Wheel Brightener and its safe on clearcoated OEM wheels.
