So at this point I have many detailing towels...Microfiber, 100% Cotton, and general towels. My question is how do you guys organize your towels? Do you use colors for the type of process...like white for removing polish...blue for detailing spray...etc. I thought about this yesterday after wiping down my wheels that had some brake dust on them and thought even after washing the towel I don't think it would be a good idea to use this on the paint in the future.
