It’s Magic!

Your stained glass is all put together.  Maybe you’ve even done the patina.  You’re holding it up to the light, marveling at the brilliance and awesomeness of yourse…er, the glass.  But what is that? Sharpie marks? Little gold numbers? Some weird haze mucking up your nice solder beads?  After ALL that work?

We will NOT have this.
Worry not, for deliverance is at hand.  You might recognize his Royal Baldness from such beloved advertising scenes as “Mopping The Kitchen Floor” or “My Clean Bathroom Validates My Existance”  Yes, it is he.  Mr. Clean, and his Magic Eraser.

These things can take crayon off walls and tea stains out of countertops. Devastating oil spill or other environmental disaster? No problem.  And they can even clean stained glass.
I wouldn’t recommend Magic Eraser in place of polish, nor as your only cleaner.  But they will save a lot of rubbing and scrubbing and smelly chemicals that also obliterate your manicures.  Also, they are made of some sort of soft foam, so scratching the glass is not a concern.  Paint and marker comes off in just a couple wipes.
Cons:  Magic Erasers will pick up patina.  It won’t be terribly noticeable, unless you scrub very hard and, really, that is why they make patina remover.  But patina residue eats through Magic Erasers the same as any other sponge or cloth, resulting in faster deterioration and a short life span.  Fortunately, they are designed to be disposable, and so come in multipacks for fairly cheap.
Give it a try, and don’t be scared of the jolly large bald man reflected in your glass.  That’s just how you know it’s working.
