I keep my car waxed and use Mr. Clean AutoDry and never have any spotting, well at least till it's time to replace the filter.I use it on my wifes van and my pick up. I would never use it on my SVTF ( Pitch Black). It leaves a film , but on the van and pick up its great because I just let it dry. If you use a good wax ,polish or glaze it won't dry spot free any more. I had just finished applying Zaino #2 to my car and had a little left over so I did my wifes van, the next time I used the Mr C autodry it didn't work. I think because of the Zaino it just kept beading up.
First off I'm quoting you just as an example.I tried this, used up the whole starter bottle on one wash and the water didn't even dry up...haha...so I used the water to claybar my car and hand washed it
Worth $20? maybe not. Minaswell buy $20 worth of carwash soap and towels.
On the contrary, Mr. Clean is outstanding for those of us that really try to keep the car's paint in great condition; primarily because the only time you're touching the car is a bit of scrubbing after applying the soap. With a soft wash mitt, you're keeping swirl marks to a real minimum.Basically if you claybar, wax, and hand wash with meguires this probably ain't for you. If you're like me and drive a dirty car for months because you're to lazy to even drive over to the car wash Mr. Clean is awesome.
