Avoid Megs Metal Polysh etc as it cuts.
Basically I'd get a good sealant on and then wash often with a mild shampoo. Topping up the sealant as often as you can.
The main thing you want to avoid is stone chips or kerbing on a lacquered rim, once the water gets in the wheels need a refurb as it can't be polished out.
I'm sure Tim at Envy Valeting will have great recommendations and products for the job.
