I was tired of me always upset by the (expensive) car wash that the wheels were not properly clean. Because you do not even want to discuss every time I bought this washing glove, to do the Rim cleaning itself. What strikes me: the glove has a reasonable cuffs, so he does not slip out of your hand. This is ever great, because I have a cloth often scratched me while brushing the back of the hand rims. Cleanliness: The material of the glove is a blue soft microfibre material that feels thick and soft. When wiping with the damp glove I have removed right away the rest of brake dust and dirt. Only when the black dots (probably tar) you have to rub longer. But that's normal, because I wanted to have no chemical tar remover, because I have expensive wheels. Then again wiped the rim wet and dried off with the Pingi. Result: All the best, the rims shine again. The glove would also good to wash the whole vehicle are good, but I want me only a separate glove order (tip from a forum, so you do not damage the paint with rims dirt).
