It works.  What more can you ask.
Works really good.  My house uses poor quality hard water and it leave deposit that is hard to clean it off.  Mr. Clean Magic Eraser does very good job of removing it.  I used this clean my bathroom sink and wow, did it clean years of accumulated hard water deposits.<br /><br />I dinged one star because you have to be careful where you want to use this scrubbing pad.  It is an abrasive so if you don't want scratch then you will have to look for an alternative gentle cleaner.
