Gotta watch that Mr Clean rig... it needs to be changed fairly often. If you don't it won't help the spotting at all. I think the refill filter says it's good for 6 washings. I guess that means like 4 if you're washing a truck and use a lot of water...

White Distilled Vinegar will remove waterspots. Rub on and wash off. But you will have to rewax, cause it will remove the wax too.

 

thanx might have to try that one.
