This is the best deal I've seen on generic Magic Erasers. Less than ten cents a sponge! Here's my earlier review: The Mr. Clean Magic Eraser a plain looking white sponge that looks like a chunk of cheap mattress foam. You wouldn't think it would do good job of cleaning anything. But it removes stains and scuffs from painted walls and other surfaces without damaging the surfaces. Magic Erasers work with water - no soap or detergent is needed.
I used a Magic Eraser once to remove a nail polish stain from some fake leather furniture and it lived up to its name. The stain was completely gone and the upholstery looked as good as new. My friend Mister Jalopy used Magic Sponges to remove decades of built of grime from a pinball machine, making it look like it had just come off the Bally assembly line.
I love Magic Erasers. People think of new uses for them all the time. Here's a car detailers who uses it to remove paint scratches and other kinds of surface damage on cars: https://youtu.be/VkBSlD60rDA
The Magic Eraser is a block of melamine foam. How Stuff Works explains why they are so good at removing stains:
[W]hen melamine resin cures into foam, its microstructure becomes very hard -- almost as hard as glass -- causing it to perform on stains a lot like super-fine sandpaper ... The cavity-ridden open microstructure of melamine foam is where the second major boost to its stain-removing capabilities comes in. Apart from being able to scrape at stains with extremely hard microscopic filaments, with a few quick runs of the eraser, the stain has already started to come away. That's aided by the fact that the dirt is pulled into the open spaces between the spindly skeletal strands and bound there. These two factors combined make this next-generation eraser seem almost magical.
The Mr. Clean Magic Eraser measures 4.6 x 2.4 x 1 inches, and an 8-pack sells for $6.47 on Amazon, where it's got a 4.6 rating. But you can buy 100 generic melamine sponges measuring 4 x 2.3 x 8 for $8.99 on Amazon.
