I just have to pass along a cleaning tip for all who might be getting ready for the Holidays, or ready to sell their homes! The off-white walls in my house were looking grimy and sad, but I'm not able to paint quite yet. I've tried different spray cleaners, but nothing helped much. Then last week, I tried the Mr. Clean Magic Eraser. It worked wonders! Smudges--gone! Black mars--gone! Weird, unexplainable marks--gone! I am amazed and thrilled. I'd tried this product years ago with no success, but Mr. Clean has it figured out now. There were some blemishes that will be removed only with a paint roller, but until I can get to that chore, my house looks much better than it did, thanks to the Mr. Clean Magic Eraser!
