The fabric it is made of is the highest quality microfibre with a high density, so Sunbeam perfectly absorbs the accumulated dirt and dust and does not leave streaks.
The cleaner is used to clean lenses, glasses, spectacles etc. You can use it to clean the highest quality optical devices without worrying about the slightest scratch. It has anti-electrostatic properties.
Hand wash with natural Nanosilver Soap or machine wash at up to 60 °C without fabric softener, then hang to dry.
