These large microfibers cleaning cloths are great for cleaning wooden musical instruments! Including violins, violas, and cellos.
Microfiber is a very absorbent cloth. It can absorb seven times its weight in water. It's also positively charged, meaning it can attract dirt and grease. Almost like a magnet. Which makes it ideal for cleaning musical instruments with rosin dust and finger grease.
