Need Help With AutoDry....

I have no idea, never used one.. try it w/o your soap maybe?

i dont see you doing anything wrong, my car is also black, it didnt leave rainbow colors or anything, however the ****ty filters only last 3 washes if you are lucky

It did that to me one time, I was so pissed off, it was all over my windows, paint, everywhere. I had to wash my car like three times to get it all off. But I think I know what I did wrong that day. You know when you get that soap (the green autodry soap) on your fingers, your fingers are sticky for a long time, even if you wash them off right away. Well I normally take some of that autodry soap and put it in the bottom of a bucket, fill the bucket up with water, and then use a sponge with that water to wash off the car. Well one time, I threw the sponge in the bucket first, then put the soap and water in the bucket, and my car turned out with tons of rainbows. I think the problem was the sponge got the soap directly on it, and then it smeared all over the car (just like it would on your fingers). I was so pissed off that day, anyway something like that may have been the problem.
