Tennis balls are not just for playing tennis. Did you know that it can also erase scuff marks on hardwood as well as vinyl floors? You should try it, it really works! It does not have to be a new piece, for as long as it is clean.
I can personally attest to this, as I have already tried it several times on our hardwood floor.
I also use it when I wash our machine washable down jackets and synthetic field comforters. I throw a couple of tennis balls in the dryer to fluff them up and decrease lumping.
Now, if only I can also explain in details how to properly use a finger pulse oximeter. Wouldn’t that be great?
