Believe it or not, one of the biggest uses for paper towels is drying your hands after washing them. Leave a NanoTowel by the sink, and you will immediately reduce a significant amount of paper towel usage. Cotton towels will not be an adequate replacement as it only absorbs a limited amount of liquid and practically never dries. The NanoTowels® also clean up spills quickly and completely. One NanoTowel can do the same job as half a roll of paper towels. Paper towels are also used extensively in household cleaning. So if you replace paper towels with NanoTowels® for just these three uses, you will eliminate the vast majority of your paper towel usage.
