Mr Clean erasers are handy-dandy little items that make cleaning stuff a lot more fun than it used to be. They are white foam sponges that wear down with use and do a fantastic job of cleaning with nothing other than water. I wonder why they work. The latests boxes of them show no listing of contents. Earlier packaging said they contained formaldehyde. That was the only ingredient listed.
Is anyone familiar with them, what they're made of, and why they work?
