New to me (for this use, anyway), and I've never seen it mentioned here before. I've tried multiple things to easily remove brake dust. I hate brake dust on my wheels. Before the unveiling, let me clarify: I'm talking about getting rid of dry dust in between washings. My wheels are in very good shape, and are well-maintained. With that in mind, I present...
The Swiffer.

This little hand-held duster is all of $4.99 for the handle and 4 covers. Refill covers are even cheaper. The handle is light plastic, so it won't mar wheels. In my initial testing, I've found I can clean the dust off my wheels 4-5 times (all 4 wheels) using just one cover (flip the cover around so both ends are equally brake-dust embedded after the first couple cleanings).

They grab the dust, they don't just push it around like a dry MF does, and they don't turn it into nasty black sludge like can happen if you try to spray and clean. And the covers are disposable.

Haven't found a downside to using them yet....

 

Brillant, I am going to have to give them a try.

Thank you for the headsup.

 

Thanks for the idea. I use swiffers on the inside but never thought about using for brake dust. I also put ceramic pads on the front, big reduction in dust.
