Was working on some rims the otherday, the inside corners where the spokes met the bezel had some serious brake dust baked on and it wouldnt come off with anything i threw at it. It was a painted rim, so didn't want to get too aggressive. But what to do here???

Did you try something like Megs Wheel Brightener? Spray it on, let it dwell for about 20 sec, agitate with brush and rinse clean.



If that doesn't get it off I don't know what will. :LOLOL
 
i used chemical guy's Grime reaper @ full strength, let sit for about a minute, then aggittated + shot it with a power washer.



Maybe a clay bar????
 
Depending on the pad it might have ate through the surface. Some pads throw really corrosive dust out.



Grime Reaper is strong stuff that I use at 5:1 so if full strength didnt move it, then i think it might just gotten to the point of no return. I have tried Meg's wheel brightener and do not find it any better than CG Grime Reaper.



On another note I just tried out CG Diablo wheel gel this weekend and it is great. I was running a 3:1 dilution and it still did not move when the gel was sprayed on the wheels.

I agree. Some wheels simply can't be saved 100%. Better to live with a little break dust than risk damaging the wheels further.
 
I had the same problem recently on some BMW wheels. We all know how bad BMW brake dust is, and this was on a 1997 model w/100,000mi and the inside of the wheels had never been cleaned. Wheel cleaners and such didn't even budge the dust. Luckly for me they were chrome, so a lot of metal polish #0000 steel wool and a ton of elbow grease and they were a whole lot better. The rears were almost good as new.



If it were me I'd try some aggressive compounds to see if that will take the dust off, just start at a small area, preferably behind the spoke in case something went wrong, and give it hell. It is unlikely you will hurt the paint on the wheel, but stay behind the spoke just to be sure.
 
Clean it with the above mentioned cleaners or same-caliber cleaners and then hit it with some clay (I suggest Auto Magic's aggressive clay, it's the best!!) and hopefully that will do the trick. If it doesn't, you'll need to inform the owner that his/her rims need a bit of restoring and then resort to some gung-ho sh!t like this http://www.autopia.org/forum/pro-de...i-f430-challenge-rim-restoration-fun-one.html Trust me, it's a lot easier than it looks. Just gotta grab yer thingies and gofer it.



Also, you can try a short and very thick (plastic) bristled brush to agitate it with, which may help more.
