What I do is first I use the Cal blade to get the excess water off. Then use a Clean dry 100% cotton towel-bath towel to dry it off. Make sure the towel isnt too wet. Thats why I have alot of extra dry towels handy. My car is spot free! Ive been doing this for over 5yrs and it works. Well of course I polish and wax it when it doesnt bead.
