Not too long ago I picked up a microfiber lens cleaning cloth and it works well. Recently I've noticed in an auto parts stores microfiber cloths for cleaning cars - glass, mirrors, etc. These cloths look more in appearance like a regular 9"x9" terry bathroom washcloth only much finer in texture. They were sale priced at 2 for $.99. Any thoughts on using these for lens cleaning? Or reasons not to?
