I've not had this problem. They do dust a lot.
Can recommend some cleaning products to you:
Espuma Revolution - non acidic but highly aggressive, absolutely not for frequent use. Will dull a gloss finish over time. Probably the most powerful brake cleaner I've encountered in 15+ years. Might find a sample on ebay. Wear gloves. Great for cleaning patios. Also a brilliant TFR provided its diluted well with hot water and you dont let it sit on a panel for too long.
Sonax Full Effect Wheel Cleaner - used this for many years now (I think I've been using it 9 years), doesnt seem to dull gloss finishes and cleans well. Does not kill ceramics either.
Good wheel brush - EZ Go brush would be my choice, durable brush that should last you many years.
