These are a great value and easy to care for since they're white. I have yet to bleach a set, but being white cotton I don't see it as being a problem. I use a new one each day and its great to have a bunch of these so I'm not doing laundry that often. Also nice to leave one or two in the car or office in case I forget it in the morning or if it got particularly dirty during the day. Far less waste than using paper towels to dry my hands. Also handy if i don't have paper nearby or on hand when I need a towel of sorts, I can use it and that's when the backups in the car or office come to rescue.
