So which was it wool or cotton?I have been using microfiber towels for drying up what moisture is left after wash for quite a while now ; I have a Ceramic Pro paint correction/coating over entire car so wash is very light as initial rinse carries most impurities off car followed with a light effort top to bottom hand wash with a nice micro mitt. final rinse water mostly rolls off car followed with a drying wipedown. But yesterday I pulled out 2 nice thicker 100% wool towels. They completely sucked up all remaining moisture on car with very little pressure/effort used. Very quick i might add; took a small fraction of the time it took with drying w a bunch of microfiber towels. 100%COTTON!!!! 100% COTTON way to go!
