i was just wondering how you guys care for you towels/clothes after you are done detailing or washing your cars. i'm not sure if its ok to mix my microfibre towels with the same load as my 100% terry cloth towels. i've read that for microfibre towels you can't use fabric softner but for cotton terry cloth you can. does anyone know if this is true? btw, i use 3m microfibre detialers clothes, they are very very good. by far better than my 100% terry cloth.
