How To Clean a Dry Erase Board Eraser

Dry erase boards, or white boards, are now a popular choice of classroom writing materials. Their main advantage over chalkboards is that white board markers don't leave off dust and debris, which can cause allergies or dryness of skin, both to students and teachers. Dry erase boards also erase easily. When you run the eraser over the writing, these come off easily, and without debris falling on the floor, like with traditional chalkboards.

After a while using your dry board and its eraser, though, you will notice the eraser working less effectively. Cleaning a dry erase board shouldn't be too difficult. However, cleaning the dry erase board eraser is a different story. The fibers of the eraser absorb ink from the marker. This means you will need to thoroughly wash and scrub this ink out of the eraser. Otherwise, the eraser will simply lose effectiveness over time. you might even find that an inefficient eraser causes smudges and streaks on your dry erase board.

You will need cleaning materials, including: paper towels, dish soap, pan, toothpaste, and rags. For best results, do your cleaning outdoors, so you don't mess up any interior space at your house or school. Here are a few methods you can use to clean your dry erase board eraser.

  • Rinse the eraser. Rinse your eraser with a garden hose. For best results, use a spray nozzle. Spray directly on the eraser, such that the water can take out all the ink that has been absorbed through time. Let the eraser dry in the sun.
  • Use soap. For dirtier erasers, you will need to use soap or detergent. Dilute some dish detergent in a dish pan, using about a teaspoon of the dish soap and a pan-full of hot water. Let the eraser soak in the solution for about half an hour.  After soaking, rinse the eraser thoroughly using running water (with the spray nozzle, if available). After washing, let the eraser air dry under the sun before use.
  • Use toothpaste. Alternatively, you can use toothpaste. Squeeze out some toothpaste onto the erasing surface. Scrub this with your rag, and lather up the erasing side of your dry board eraser. Rinse the eraser thoroughly under a faucet or with a hose.
  • Use paper towels. For lighter cleaning-such as in between soapings and washings - you can use paper towels to absorb the ink. Wet some paper towels and press these against the eraser's erasing surface. Leave this on for a few minutes, until the paper towels have absorbed all the ink from the eraser.
  • Use alternative erasers. If you find cleaning your dry board erasers regularly too cumbersome, you can use disposable alternatives, which can be just as clean, but without the need for regular maintenance. For example, you can use a dishwashing sponge, with the non-abrasive surface as the erasing side. You can also use baby wipes or wet tissues. These items are consumable, and you can simply throw them out when they are too dirty.
