A scrim or gauze is a very light textile made from cotton, or sometimes flax. It is lightweight and translucent, which means it is often used for making curtains. The fabric can also be used for bookbinding and upholstery. It also can be used as cleaning tool for window cleaners. We use it a lot at work in order to wipe off all the frames around windows after using a squeegee. It’s very practical for small stains on windows as fingerprints, sweat marks, etc.
