Magic Erasers are made up of a melamine foam, which has undergone heat compression to increase their durability, explains Brashear, who says that this is the extent of their manipulation.

Clean Magic Eraser Sheets are designed to compress and break down as they're used, like a pencil eraser. How long they last depends not only on how many times you use them, but also how rough the surfaces you use them on are.

Muscle out grime in nooks and crannies, hard to reach corners, and more. Ideal for scrubbing greasy stove tops, tough stains in microwaves, grimy fridge handles, hard water spots and stains on sinks and faucets, in the bathroom, and even more! For when cleaning spray and wipes won't cut it.

It works because when melamine resin cures into foam, its microstructure becomes almost as hard as glass – causing it to act like super-fine sandpaper on stains. The abrasive foam loosens up dirt and grime, and the open microstructure of the foam sucks it in and traps it there.

Then. They add sulfur as a curing agent accelerators to help the sulfur do its job and red coloring they blend everything for five to ten minutes until the mixture is the consistency of heavy dough.

Mr. Clean Magic Erasers are a household staple for removing stains, grime, and build-up. So how does a Magic Eraser work? They make these magic sponges from melamine foam - a versatile and safe cleaning material that can get rid of everything from permanent marker stains to scuff marks.

Its sponge-like cell structure is delicate enough that it wears off on the durable layer under the stain. In other words, the scrubbing of the sponge loosens the dirt, while its open-cell structure soaks up and grabs the grime.

Clean Magic Eraser Sheets, just wet, squeeze, and erase. The flexible sheets make it easy to erase on all kinds of surfaces, and when you're done – the sheets are disposable for easy cleanup.

All-Purpose Cleaner Mr. Clean® Multi-Purpose Liquid Cleaner cuts grease to remove grime and leave a light, fresh scent as you go. Use it to clean dirt on linoleum, tile floors, toilets and bathtubs.

Without regular cleaning, dirty sheets can contribute to allergies, skin breakouts, asthma, and more.

It's a type of hard plastic, and when it is made into a foam a fine porous surface is created. The foam is made of super-fine fibers that lift and trap dirt and rub out marks. These thin, glass-like fibers are abrasive, so Magic Erasers® can be thought of as a cross between a sponge and fine sandpaper.

The sponge is made from formaldehyde-melamine-sodium bisulfite copolymer, so there are trace amounts of formaldehyde present in the sponge, but it is not in the same form as the formaldehyde we remember from science class.

These include isoprene-isobutylene (butyl rubber), styrene-butadiene, and ethylene-propylene copolymers. Synthetic rubber began to replace natural rubber in erasers by the 1960s. Since the mid-1990s, erasers have been made nearly exclusively with synthetic rubber, primarily polyvinyl chloride.

Products made of hi-polymer are considered to be of the highest quality because they don't harden and break over time. They also allow you to erase stubborn marks quickly and smoothly. You can also find pencil erasers made of rubber and PVC that offer enhanced durability.

The combination of hard and soft structures within the “sponge” is what makes the magic. Melamine foam is harder than what makes up most stains, but it's softer than most of the surfaces those stains are on. This allows the Magic Eraser to remove stains without scratching the surface underneath or around the stain.

Magic Eraser is made of superfine foam which is abrasive and can result in rashes or burns, even with gentle rubbing. Because of this, the Magic Eraser should never be used on a child or adult's skin.
