diylife.com has a great article on their website showing 20 extra uses for a Magic Eraser. HERE is a link to the article, and below are the tips listed:
1. Outdoor Furniture and Toys
Take grungy white resin or white painted furniture by lightly scrubbing with an eraser cleaning block. The eraser gets into crevices and cracks while leaving paint finishes intact. The same principle applies to outdoor plastic toys.
2. Pool Liners
Pool owners, this will make your life easier: A gentle scrubbing on your liner will get rid of the water mark better than any other product.
Take an eraser to scuffs on just about anything made from vinyl: siding, boat seats, shoes, etc.
4. Car Interiors
Clean the car seats with an eraser block: Go lightly on leather, but it's okay on fabric and vinyl, lightly scrub the car steering wheel. Eraser blocks get rid of grease streaks left inside after the car's been to the shop, too.
Clean your car's hubcaps with an eraser for a water-free car wash.
Get rid of last year's drippings that are pooled in the back of the fridge. It'll take a whole eraser block, but it gets the job done. The seals that have gotten a bit black and moldy will also respond well to an eraser.
7. Dishwasher Interior
What are those colors inside your dishwasher from time to time? Lime, mold, ewww. Just take an eraser to them and the stains will banish.
8. Bathtub and Sinks
Getting rid of dirt and water marks is easier (and not so gross) with an eraser block. Bathtubs can take a tough scrub, but go lightly on sinks -- even a light scrub gets rid of that caked on dirt that you often can't see until you try to get it off.
9. Rust Removal
Scrub anywhere (around pipes in kitchen and bath) that you see rust.
A magic eraser gets rid of oil and dirt that has built up on your keyboard and mouse; you can use it on laptops, too.
Use one on your phone's mouthpiece, too -- it gets rid of the same grime that builds up on your computer.
Wherever there are smooshed bugs (porch pillars, car windshields, interior walls, exterior doors, exterior light fixtures) wipe them away with an eraser block.
13. Glass Stove Tops No need to have special stove top cleaner on hand, get rid of burned-on food by lightly scrubbing until the gunk is gone.
