For anyone looking for cheap 100% cotton rags to clean your car with, try this. Find someone who works at a hospital and works in surgery. In every surgery, they open up these "kits" with all the tools and whatnot for that procedure. It also comes with a few blue rags. They never use all of them, but they cannot use them for another case. So they get tossed. My wife brings these rags home by the dozen. They are usually 12"x24" and work great for cleaning rims and detailing your car.

 

Watch your paint. For paint surfaces you should use only brand new 100% soft cotton towels made in USA,take off the tags, and remove all stitching, otherwise you will scratch your bodypaint. This is a recommendation courtesy of ZAINO..
