AMERICA’S PREMIER CAR DETAIL PRODUCTS - Since 1999, The Rag Company has been committed to making the highest quality microfiber and car detailing products available. Always the better value! Our BIGGEST and BADDEST drying towel to date! The 1500 drying towel was created for heavy duty drying applications in automotive, commercial trucking, and recreational vehicles. The 1500 drying towel boasts a 1500GSM density with a premium 70/30 blend twist loop design. During our testing, the 1500 could dry MULTIPLE full-size trucks with a single towel. We found the 1500 was also ideal for boat drying and use in commercial trucking applications. In comparison to our famous Gauntlet Drying Towel and Liquid8r Drying Towel, the 1500 offers a more robust drying experience. For the BEST experience using the 1500, we DO NOT recommend the use of drying aid chemicals such as sealants or waxes. Washing the towel before first use, and washing with Rags to Riches Microfiber Detergent is always recommended to maintain maximum absorption.
