Sure I buy paper towels and the occasional sponge. Maybe a special chamois but I don't ever remember buying a 'rag'. I've only used one 'wiper'. Cleaned the computer and tv screens well. No scratches on stereo equipment. I believe they are supposed to be able to be washed. We'll see. They are a good size and so far so good!
These towels are 16 x 16 which is a good size. They are very absorbent. I haven’t found that they’re leaving any lint behind. My windows are streak free! I definitely recommend.
