I use the Mr. Clean system. But I don't bother with the drying function. I just use the full rinse - it's still filtered water even if not de-ionized. And I use a leaf blower to dry. It does pretty well at not leaving water spots if you are careful about it, but I clay and wax most every time I wash making it a non-issue.
