Is there a such thing and does it REALLY work?

 

i wonder as well. I had having to work to get break dust off.

 

just keep a good coat of wax on your wheels, makes them much easier to clean, i use a couple of coats of liquid glass topped with meguiars #16, than to clean just use eagle one a2z and wipe with a sponge.

 

can you do that on chrome?

 

Yes you can use a wax or sealant on chrome wheels too.
I have FourStar UPP x2 and Meg's #16 x2 on my wheels, and brake dust has a very hard time sticking to the wheels. To clean them, I just use the usual car soap and water solution.

I just received my new wheels today (2K2 17s) and I did this...

Clean with car soap
Clean with P21S Wheel Cleaner
Clay
Klasse All In One
Wolfgang sealant
The wheels are VERY smooth right now, and I am very confident that brake dust will have met its match here.

The wheels will get a total of 5 coats of WG sealant in the next week, and maybe a coat of Meg's #16 to finish it off.

 

I use NXT polish. Do I just do the wheels like I would do the body of the car

 

yes, apply, let haze, buff off

 

I am a totally newbie. What is brake dust? Where does it come from?

 

Brake dust is the result of the brake pads wearing while squeezing the brake rotor to stop your car. You'll notice it as a grey / black powder on your wheels. It can be a pain to get off if you let it build up.
