Hello together, I always drive aluminiums on both cars all year round. Depending on the weather conditions, they look more black than aluminium-coloured. Washing systems and wash boxes don’t get them clean. So you have to put on HAnd again and again. I have now discovered by chance rim brushes for cordless screwdrivers. So you could save yourself the scrubbing, if it then works like this. Does anyone have experience there? Do they fit on any cordless screwdriver, u and how much power must the cordless screwdriver have? Thanks already and greetings rebel
