Review
I've been trying lots of brake dust cleaners and this one is about the best one I've used so far. I like it because it's inexpensive and easily available. I have found that I have to use my wheel brush to completely remove the brake dust and as I agitate the solution, it seems to become jelly like. When this happens, I've learned to rinse off immediately. If the wheel doesn't become complete clean, I have to repeat the process. I always wash my wheels first before I start washing the car's body. I have used lots of Meguiar's products and have been very satisfied.

What I like
Inexpensive, readily available, and simple usage.

What I do not like
May take quite some time 'learning' the product to unleash the great results it has to deliver.
