Says they're for cleaning your hands, which they do a great job. I also clean tools, parts, most anything dirty or greasy. They keep working as long as they're damp. When working on my brakes, I would clean my hands then drop the towel in a baggie then use it again 10 minutes later, put it in the baggie, then clean the tools, and maybe throw it out. Great tool for my workshop!
