Guys .. I am planning to do a good clean up on the inside part of my rims. I was looking at them from the inside and they are full of black grime and brake dust that has builted up for years maybe. Outside is always clean. Has any of you guys done it? Is it worth it..I know this requires taking the rims off and wash them from inside out individually. I wonder if they will look the same in a couple of weeks from the brake dust? I dont think so. I think i will defitanely see the difference. What do you guys think?

See my wheels on the small picture i forgot the rims style i have.. i love them.. 20"
