I washed my car yesterday. Today I noticed there was a haze on the caliper. Any idea why and what do you guys use to clean your wheels?

I use Adams wheels cleaner. What I noticed is if you don't drive the car after washing the rust builds up on the routers. When you drive it later on the rust ends up on the wheels when brake is applied.
Therefore take it out for a short spin after washing and drying.
