CONCOURS 100% COTTON TOWEL SET FOR THE TRUE CAR CAR ENTHUSIAST.
You should use the same towel for a particular purpose each and every time you wash and wax your car. Towels with wax residues will not dry as well. Towels with a minute amount of grit have no place being used as a buffing towel. Our towels are made of the finest 100% cotton and have WASH, WAX or DRY woven into the towel to keep them separated! The Wash Mitt can be filled with water to flush out trapped dirt after a wash. The DRY towels are the perfect size. Not so big that you have a hard time moving them around when they're wet, but 27" x 35", the optimum size. You won't even find a polyester care tag sewn on the towels! Polyester, no matter how minute, scratches paint. If you are using a towel with polyester in it, or you are not sure if it has any, stop using it now! Set contains 2 each 27" x 35" Dry Towels, 2 each 16" x 25" Wax Buffing Towels and one 8" x 11" Wash Mitt. Dense, 100% cotton terry jacquard weave. These are so nice your spouse will probably steal them for the guest bath. We offer you the very best in car care towels. Made for you in the U.S.A.
