If your removing and just cleaning them then elbow grease shampoo apc and non scratch kitchen sponge. then if its really caked on brake dust iron x. but wonder wheels do one at halfords but not tried it. If your keeping the wheels on to clean the the above first then Brake duster as its not so strong as iron x and let it dwell for 30 mins and agitate it. Do not use ix in rirect sunlight imo. But if your having referb then let them sand blast them save you doing the hard work. Remember guys always use a good wheel sealant after working hard to keep your wheels clean using just ph shampoo
I recommend permanon aircraft supershine for wheels as it withstands the heat of brake dust up to 300 and it also repels dust and hates dirt
