Well first off, most types of rags produce some type of lint that is left behind when being used. If you are cleaning glass, windows, mirrors, automobiles or electronics you will want as little lint as possible. There is nothing like cleaning a window and seeing lint all over it once you finish. That’s just not right! To get the best results with a wiping rag in these situations you want to use a low lint rag.
Lint is a small, fine fiber that detaches from the surface of cloth and yarn. With cotton a tighter weave means less lint but also means less softness. Typically the softer the item the more lint you will see. A lint free cloth is a special type of cleaning cloth that does not give up any fluff or lint when being used.
