How to Clean a Whiteboard Eraser


Lisa asked: How can I clean a white board duster without wrecking the felt?

White board dusters that get a lot of use quickly fill with pieces of dried marker ink. While often these are just replaced, they can be cleaned to help them last a little longer. Follow these guidelines to keep your duster clean and lasting longer.

You Will Need:

  • Soft brush (baby brush works well)
  • Water
  • Mild detergent (optional)
  • Paper towels or clean towel

Steps to Clean the Duster:

  1. Most of the particles can be removed from the felt just by brushing them off. Begin by brushing the surface lightly with the soft bristled brush using a back and forth motion. Start at the top and brush all the way to the bottom.
  2. Repeat once if necessary. The goal is to remove as much of the loose marker dust as possible.
  3. In many cases, this will clean the eraser enough that it can be used again. If a deeper clean is required, continue with the following steps.
  4. Mix a small amount of mild detergent with water.
  5. Dip the brush in the mixture and use it to gently scrub the felt. It is best to work from top to bottom again, scrubbing in circular motions.
  6. Rinse the felt completely with cold water
  7. To remove excess water, press the duster on a towel or stack of paper towels. Do this several times until as much of the water is removed as possible.
  8. Allow the felt to air-dry completely.
  9. If necessary, use the brush after the duster has dried to gently brush the felt to restore the pile.

Additional Tips and Ideas

  • Avoid using harsh chemicals or hot water on the felt portion of the duster.
  • Only clean the duster when necessary. Most dusters are not designed for extensive cleaning and may need to be replaced after several cleanings.
