| If you leave those wheel cleaners on your car for too long, you can get some nasty stains on your wheels. I would recommend staying away from all wheel cleaners.
As for dishwashing soap, its best not to use it either. Just think of your wheels as an extension of your paint. The dishwashing soap removes wax and could potetially harm the clearcoat of the wheels.
Just get down and dirty with a specific mitt/spunge/brush to clean your wheels. Remember, don't use the same sponge on your wheels as you do the rest of the car. All those tiny shards of brake pads can scratch your paint.
