Brushes...

I was in HF picking up some stuff and came across a 9 piece Tube/Pipe Nylon brush set for around 5 bucks. They feel decently soft, but still stiff enough, was wondering if anyone knew if they be safe for clear coated or painted wheels?

If not, then I sure I can find a use for them, like cleaning those little hard to get spots in the engine bay, or the under carriage.

Thanks for the tip, and the advice. I do have dedicated brushes for the interior, but lacked some smaller brushes that can fit in the spokes and small areas.
