I know you probably already know about the Magic Eraser. But on the off chance you have yet to discover this divine invention, let me just say, "magic" is not an overstatement.
scuff stains on your walls and baseboards
weird stains in your kitchen sink
tarnish from silver
marks on vinyl siding
coffee and tea stains
mirrors in bathrooms (to stop fogging)
adhesive residue from stickers
dried splatters inside microwave
hair dye from countertops and floors
rust, grime, nail polish, melted plastic, grill grates, etc etc etc...
You get the idea. Buy one already and try it out if you haven't yet. You will love it!
And recently Mr. Clean added a new member to the magic family...
I was buying this at the grocery store and the checkout lady's eyes boggled... she said "I didn't realize that magic eraser made a bath scrubber! I have to get one!"
Yes you do lady, yes you do.
Enjoy your clean house!
