Seriously, this is the best product ever invented. It has helped me in a number of ways. It cleans grout, scuff marks, crayon on walls, pens on leather, dirt on car upholstery. There is literally no end to what this amazing product can do. I use it daily. I just want to say thank you to this amazing man. I have tried the imitation Target brand and it does not even come close to what Mr. Clean can do. If you even think of trying to save $1 don't do it. Please, give credit where credit is due and just buy Mr. Clean eraser pads, you will not be sorry, in fact you will thank me.
