Optical Image cleaning cloth, excellent choice for cleaning lenses, tablets, cell phones, computer screens and so much more. These cloths dry the lenses very effectively with the terrycloth side then flip it over to polish with the high density microfiber to trap oils and avoid smearing. The gentle fabric does not scratch and is designed to remove dirt, dust and oil from your fragile surfaces.
If the cloth becomes dirty it's as easy as throwing it in the washing machine. Use bleach free detergent, and it should be free from fabric softener.
