For years, I’ve wondered what Magic Eraser was that makes it so magical.  Let’s face it, it’s a sponge.  But then I started doing some research on it.  The Magic ingredient?  Melamine Foam.  It’s an abrasive foam so don’t use it on your car….it will scratch it. A similar product is Bounce.  Its great for getting bugs off the front of your car but for darker cars, using this may result in fine scratches.  If you have hard water ruining your glass shower windows….use Lime Away.  That stuff wipes the hard water residue right off the glass with a scrub sponge.
