Is the Magic Eraser Really Magic?

The obvious answer to that question is “No,” which is mildly unfortunate, because think of how much more money the wizard world could have for upgrading the Floo Network if they were in fact creating and selling these bits of cleaning magic to us Muggle folk. But since it isn’t magic that makes Magic Erasers and other soft foamy scrubbers work so well, what is it?

The answer is science, my friends. Specifically, we have chemistry and the good people at BASF, a German chemical company, to thank for this great invention. Those soft foamy scrubbers are made from melamine foam, whose ridiculous scientific name is formaldehyde-melamine-sodium bisulfate. I know; it’s a mouthful. The melamine and formaldehyde combination leads to a lot more than just magical cleaning supplies; those two are also used to make countertops, white erase boards, insulating materials, glue, dinnerware, and fire retardants.

I expect that a handful of people have their eyebrows raised right about now over that word “formaldehyde.” Yeah, formaldehyde, a common preservative and carcinogen, isn’t a great thing to have around the house. Fortunately, what’s found in Magic Erasers et al is a chemical compound created with the use of formaldehyde on melamine and not actual formaldehyde. There was a small dust-up about this a few years back and Snopes has it all pretty well covered.

The melamine foam works like very, very fine sandpaper. It is microporous and if you were to look at it under high magnification, you’d see a tangle of fine, hard, fibrous strands. I was unable to find a creative commons photo of this thing, but if you click here and scroll to the bottom, you’ll get a chance to see what I am talking about. This mixture of hardness and holey-ness is what makes the melamine foam such an effective cleaner. It’s also why it is always better to test the foam on a small, discreet area first and then launch ahead on into a project – this powerful abrasive may be more than you bargained for on painted or otherwise delicate surfaces.

And speaking of delicate surfaces, don’t rub this stuff all over your body. This foam can clean anything off of anything, and there is no reason to be putting that all over your skin. I know, it seems like common sense, but in my research for this article, I found many, many, many warnings about rubbing Magic Erasers on people. I also found many, many, many warnings about eating melamine foam. Again, it seems like common sense.

However, melamine is not unknown in food. In 2007, pet food made in China was recalled because of the high concentrations of melamine. Melamine was added to sub-par pet food to falsely suggest that the food had more protein in it than it actually did. To be clear, China isn’t the only country facing this type of issue: a similar problem with livestock feed occurred in the US. Countries including the USA have strict guidelines about and tests for melamine in food. Sadly, this has not fully stopped the problems of melamine being used in food for human consumption: in 2008, China saw a worse situation unfold when melamine had been added to infant formula.

So what’s the final word on Magic Erasers? They’re non-edible, non-rub-able, surprisingly hard and holey-amazing bits of foam that have the grit and abrasiveness to deal with almost any mess.

    How interesting! I’ve always avoided the magic erasers because of suspicion over how they did manage to get things so clean. Think I may give them a try now, if the need calls!

    I thought these didn’t exist in NZ, but apparently I’m wrong. I have some stubborn marks on my lino I shall attach with these!

    I avoid them generally because they have scary stuff in them, but whenever I move out of an apartment, I pull those suckers out. They’ve saved me from many a lost security deposit.

    I remember when the product premiered, it was one of the hosting challenges on The Apprentice. I totally didn’t believe it worked. But all these years later, it’s one of my favorite cleaning products.

    I refuse to believe that they are anything short of magical, even if there is a SCIENCE! explanation for how they work. Anything that takes dog slobber off my walls is pretty miraculous.

    Having worked as a professional cleaner for three years or so, I have to confess my undying love for the magic erasers! At home, I’ve converted to homemade cleaning products and solutions, but you’ll take my magic erasers when you can pry them from my cold dead fingers. And even then, I might reanimate and fight you for ‘em.

    I have been WAITING for this post to go up. As some may know, I am firmly indoctrinated into the Cult of the Magic Eraser, and while I’m pretty sure they’re made up of space clouds and sorcery, the melamine thing makes perfect sense, too.

    Seriously, though, you have a stain/marking/gross film on a surface that can handle a little abrasion?

    It cleans EVERYTHING. But yeah, don’t eat them. And as Ailanthus says, don’t rub it on your skin. And use gloves if you’re using them to clean, because the abrasiveness can irritate your fingers and hands, too.

    Wow!  I have been wondering what the magic erasers really were.  I just assumed, strong cleaning meant chemicals.  As for the no brainer about not rubbing in your body- you still hear of stories where people do just that.  Um….think first.

        I’ll go ahead and admit off-label usage: I’ve used them to remove self-tanner streaks. But VERY gently, and, like, one pass over the area. I don’t recommend it, since I can see how easy it would be to give yourself a burn. My skin is the exact opposite of sensitive, so I can abuse it with little effect.

        I’m one of the idiots.
