In most cases, you need to use two NanoTowels®--one wet and one dry.
For example, if you are cleaning glass and want to avoid using glass cleaner, just scrub the dirty glass with a damp NanoTowel, and then go over it with a dry NanoTowel for no streaks and crystal clear glass. The same goes for stainless steel, wood and just about everything else (particularly good for dusting) Use them for dusting, washing counter tops, floors, bathrooms, glass, stainless steel, spills. Also, they are great for washing a car because they are so soft, they will not scratch, and they absorb a huge amount of water.
