is there a product/method to completely remove baked on bmw brake dust

on wheels that have not been cleaned properly in 2 years??



:sosad
 
Good luck with that, my parents have an X5 with some old baked on brake dust and nothing seems to get it off. I haven't tried acid but that might do the trick. Next time I wash it I may just use some Wheel Brightener at a higher than normal concentration.

I was talking more about the pure, singe your nose hairs acid cleaners. I used to work in a detail shop and we had barrels of the stuff. It got almost any brake dust off but I'm sure it wasn't the safest... And I've used them before, just never on the X5.
 
I had caked BMW brake dust on my chrome 335i wheels. The previous owner had not cleaned the wheels in 9 months. I researched on the web for help. I ended up using WD40 and NevR Dul chrome polish. Made a world of difference. I spent around an hour on each wheel. It takes alot of time, elbow grease, and effort to make the wheels look good agian. They are not perfect yet, but I know if I tried hard to get it all off with NevR Dul I certainly could.

I've read that oven cleaner works for baked on brake dust. Any truth to that?

Oven cleaner usually is highly alkaline, and contains caustic ingredients such as sodium hydroxide. I would not use oven cleaner anywhere near a car. Baked on brake dust is inorganic soiling and needs an acidic product to remove it. The problem with acidic wheel cleaners is some contain acids such as HF (hydroflouric) and ABF (ammonia bi-flouride) that can be toxic if used carelessly.

WB might work at 2:1 or 1:1... don't let it sit too long, and use gloves while you brush. A pressure washer helps too.

I have found that Megs WB doesnt work as well at higher concentrates, I would use at 4-1, some soft and firm brushes and keep it wet, if you can take the wheel off, it will make things much easier
 
At Danase.com Bob sells a wonderfull product called Assassin. Worked wonders on my neglected 7 year old wheels.

Got ya! It didn't sound safe, but I've read that suggestion more than once. I'm a big P21S fan, but even that has it's limits.
