Nothing looks better than shiny polished rims on a clean car. It's easy to use a rag/wash mitt/etc to clean the outside of the rims. But what do you use to clean the inside of the rim (the hard to reach part sometimes called the wheel well or other things)?

It's difficult to reach in there and I hate to use a brush for fear of scratching. Any suggestions would be appreciated. My terminology may be incorrect, but you get the idea.

 

Fender wells:
Rinse wheel wells thoroughly with water, apply a citrus-based de-greaser and let it soak in. Agitate with a long handled angled boar’s hairbrush before rinsing (Groit's).

Dry surfaces with a terry cloth towel before applying a water-based rubber/vinyl dressing; wipe off any excess and buff surfaces. This simple detailing step will provide a `frame' for your wheels and tyres and provide a completely finished look to the vehicle. After cleaning wipe surface with a solvent type cleaner and then they can be painted with a satin paint to maintain an as-new look (Groit’s Satin Black Spray Paint)
