Hi there,Been wondering if there is a better way to clean the brake dust off the rims. With the 18-inch double-spoke M light alloy wheels (style 350M), it is quite difficult to stick my hand in between the two spokes with a car wash sponge/cloth to clean out all the brake dust, not to mention, it takes a long time, and you can rip your skin in the process.Is there any other way to clean it? I saw rim cleaners in spray bottles being sold at DIY stores, but I don't know if it is safe to even use those. I was planning on getting a spray bottle and filling with car shampoo+ water, and spraying it, cause I notice car shampoo clumps up the dust together. Wonder if it will work...Any other tips?Thanks!
