wheel cleaning & maintenance

[THOMAS TAUSKEY]

Didn't find any info in archieves re: cleaning tools/chemicals/technique for cleaning wheels, esp. BBS latticework PIA's. 
As for myself: wheels off car, face up, waist high ....mit toothbrush, wheel cleaner and water for starters, progressing to Dremel/air die grinder for the harder spots. 
The BBS wheels are painted, but with what kind of paint/hardner/topcoat combo? 
Can they be successfully spot painted - say to repair curb rubs?
What sort of wax to apply- and what a pain that will be on these wheels unless it can be sprayed.
