My Z is getting pounded right now by the rain but I was able to clean the brake dust off my wheels yesterday before the rain started
I posted something about this wheel wax last week but now that I went a week driving around it really helped to protect the wheels especially if you're running a more aggressive pad like I am
Chemical Guys Wheel Guard WheelWax & Rim Cleaner
It makes the wheels easier to clean which is always a plus
