Im tired of hand cleaning (with a wet soapy rag) my wheels. I'm looking for a brush recommendation to ease the and expedite the process. The wheels in question:
They are a real PITA and haven't had any luck finding a brush that can get in all the nooks and crannies.
Also, where I currently work there is a ton of construction going on and keeping an old car that's a DD completely clean is becoming a real task. My wheel wells are pretty much stained brown from all the dirt and I've used wheel cleaner with a tough bristle brush with not much luck. Would it be out of the question to use a flat black spray paint to black them out again?
