I purchased this cloth to clean a lot of my sterling silver jewelry. When I got it I noticed that immediately my hands started turning blue and ash - both white and blue- kept falling off of it. Having used these clothes for LOTS of years (NOT this brand but them in general) I knew that this wasn't what usually happened. It did not clean my silver, instead, put blue all over it and me. I went to a jewelry store, got a cloth and got the blue off as well as the tarnish. Don't buy, doesn't work and I have no idea what chemical sheds all over you, your clothing and jewelry.
