E-cloth Glass Cleaning and Polishing Cloth 5 "Just the thing" Helen 03 August 2018 We have many of these around the house. They are brilliant for cleaning mirrors, no more smears. We use them for cleaning our glasses, much better than the tiny little cloths which come in the case. There is one in the car for clearing the inside of the windscreen when necessary. Great on TV screens and glass tables. The list is long.
