dish soaps not good at all. you could have listened to the people here
, over 4 months ago.
if you don't see much difference in paint quality on your wheels now, from 4 months ago, then the cleaner your using probably isn't too abrassive. but even still, I'd never use dish soap on my wheels, I'd rather scrub harder with car wash soap.
and listen to dudesky, if you get dish soap on your car you better enjoy waxing. the soap will also take the tire protectant off of your tires.
