You can't really stock up on erasers because they dry out.” (This idea inspired the slogan on a t-shirt the Erasable podcast sells: “Pencil is forever.”) Advincula explained: “Over time, some of the rubber properties can be lost because of oxidation or chemical degradation.
Do kneaded erasers wear out? They do not wear out, but they can become too hard, crumbly, or dried out.
Rubber pencil erasers get hard and brittle over time and don't work well because the rubber is oxidized.
Store your eraser in a container that's dark and air tight. This way you'll always know where it is when you need it (provided you put it back into its place after using it). And you will be able to use it for a longer period of time as it stays in a good condition.
1. Don't use them dry. Part of the magic of these erasers is that all you have to do is add water to activate them. However, it turns out that these plushy pads are even more abrasive — and can, therefore, do more damage — when dry, so adding water actually helps soften them.
Use and re-use eraser — soap and water keep it clean! Fully washable for quality erasing every time. Don't worry if you've done a lot of erasing already — the soft-pile eraser can be cleaned easily with soap and water, extending its superior erasing abilities.

“These days they're usually colored to be pink because that's the color we've come to expect them to be, which can be credited to the trusty Pink Pearl.” Pink Pearls are still produced today, under the Paper Mate brand. They're now made of synthetic rubber, rather than natural rubber and pumice, says Weaver.
Here's why you need to ditch the pink eraser:
Eraser is fresh, not hardened, and first time used. Here's the deal with white erasers, not only do they erase pencil marks better than the old-school style pink eraser but because they're non-abrasive, they leave the paper fibers relatively intact.
Rubber and a few other similar products tend to have this nasty habit of decaying over time when exposed to the elements. They dry out and become hard and brittle, and tend to break off into pieces.
As the abrasives in your eraser are rubbed against paper, friction produces heat, which helps the rubber become sticky enough to hold onto the graphite particles. As the rubber grabs the graphite particles, small pieces of combined rubber and graphite get left behind.
If you are on a Background layer, the Background layer cannot be transparent. It will erase to your Background Swatch. Type "D" to reset the swatches to black and white. Convert the Background layer to a regular pixel layer by clicking the lock icon in the Layers panel.
According to DIY By Hand, Magic Erasers should last between one to 10 uses. This is quite a range, but depending on what you're using yours for, it will last a different amount of time. There are a few things you could be doing that will degrade your Magic Eraser faster.
The original eraser, developed in 1770 by British engineer Edward Nairne, was made from natural rubber, otherwise known as caoutchouc, latex or gum elastic. Natural rubber is usually derived from the sap of the Brazilian Pará rubber tree (Hevea brasiliensis).
Today, erasers are usually made from synthetic rubber, which is a polymer. When it is made, a chemical called an accelerator is added to help join the monomers, or small molecules, into a polymer. The original accelerator had a pink color; the erasers sold well and the tradition has been maintained.
Imported from Japan, the Pentel Ain is made of PVC, a specialized polymer material that produces less dust and causes fewer abrasions on paper: just a few light, gentle strokes are able to remove any unwanted marks.
Black and coloured erasers do not leave any colour from the eraser on the paper. They are dark so that when erasing on dark paper a white ghosting effect is not left as can happern with white erasers. They also look less grubby when they are dirty.
The white side erases graphite, and the grey side erases ink. The white side erases graphite, and the grey side erases ink.
While these erasers were cheap and plentiful, they had a distinct disadvantage: They were, you know, made of bread. They were susceptible, like all bread, to mold and rot.
Most erasers will have to be disposed of in the general waste bin. Erasers made solely from natural rubber may be biodegradable.
Before the invention of rubber erasers, people used tablets made of wax to remove lead or charcoal marks from paper. Even materials such as sandstone and bread have been used historically to undo writings or scribbles.
Yes, Windex can be used to clean a dry-erase board, but only on certain types of boards. For porcelain and glass dry-erase boards, Windex is an effective chemical-based cleaner. However, Windex can damage the surface of melamine dry-erase boards, so it is not recommended for these types of boards.
Never use any kind of glass cleaner or anything containing ammonia, abrasives, alcohol or bleach. Use soap and water or an acrylic cleaner (like Brillianize or Plaskolite Plastic Cleaner) to wipe down the surface.
You may even be able to clean gunk from your eraser with household soap and water. Scrub your eraser until the gunk comes free and then rinse it clean. Allow it to dry completely before using it.
