For the last couple of washes I tried the Meguiar's Hot Wheels Product. Well I wasn't too happy with it. I found that I still needed to extend a rim cleaning brush to get into the rear excesses of the rim as well as sponge behind the 'Y' spokes. Also, I estimate it takes one half bottle of the product per wash. Kinda pricy. Just using a sponge, brush, and sudsy water get the rims, in my opinion cleaner, and more cost efficient. I do wear platex gloves to protect my skin from sharp metal. It's just the bending down with my old bones and joints that really a problem. Still using the BMW brake pads that do not squeek.
