Over the winter I used the jet wash to clean the car, the big down side of this is that the aloys never get a good clean. More recently when Ive been hand washing the car I have not been able to get the wheels clean the built up grime just wouldnt shift. Someone lent me some wonder wheels cleaner to try out and it worked a treat
Just a case of brushing it on leaving it a while and then cleaning off with soapy water.
