1) I noticed you used an air compressor along with the paint brush to clean the wheel from brake dust.
Was it really necessary to do that? I would have gone straight to the waterless wash and the microfiber cloth.
2) I noticed while you were cleaning the calipers with the waterless watch you were avoiding the rotors.
My thoughts: Why was it necessary to avoid the rotors. They can get wet correct?
yeah no worries, ideas always welcome.
1) necessary? No, but it's a bit more thorough getting as much of the dust and dirt blown off before applying liquid, especially in the corner areas.
2) I'm sure they'd be fine if you didn't care if they got wet, but I do, my car never see water, I don't want to introduce any of the rotor areas to moisture if I don't have to. There's no reason to spray them down but if you do be sure to blast them out with an air compressor thoroughly.
There's no "right" way to clean your wheels but this is the way I do it and it may help someone who doesn't have any idea which direction to go.
