No matter what kind of glassware you have, the RIEDEL Microfiber Polishing Cloth is the perfect tool for keeping it clean and polished. It can be used dry or lightly dampened, and cleans thoroughly without leaving any scratches or lint behind. Plus, it dries and polishes at the same time – so your glassware will always look its best. And if it ever gets dirty, you can just throw it in the wash – it's tough enough to withstand temperatures up to 90 degrees.
