Every domestically made towel is washed several times by the manufacturer to remove excess dye. Unfortunately, this leaves the towel looking limp and used. So, manufacturers then "sizes" the towel to make it look more attractive and new again. This "sizing" process uses a starch and silicone mixture that will scratch and contaminate your paint finish. Zymol towels are not "sized". Our mill dyes, washes, dries and ships directly to us for you.
