Can You Wash a Kneaded Eraser?

Yes, you can wash a kneaded eraser, but it’s better to try cleaning it without water first. Kneaded erasers are made of a putty-like material that picks up dirt and debris as you use it. The good thing is that this material can clean itself to some extent.

Art supplies like kneaded erasers are great for erasing pencil marks precisely. But, over time, they can get dirty and less effective.

If you’re wondering if you can wash a kneaded eraser to make it work like new, you’re in the right place.

In this guide, I’ll explore the answer and give you a step-by-step guide on washing your kneaded eraser correctly.

Dos and Don’ts of Washing Kneaded Eraser

Maintaining your kneaded eraser is essential to keep it in good condition. Follow these dos and don’ts for effective washing.


  • Do fill a container with lukewarm water. The gentle temperature helps soften the eraser without causing damage.
  • Do knead the eraser before washing it to make it more pliable. This ensures better absorption of water and cleaning agents.
  • Do use a small amount of mild soap or detergent if the eraser is particularly dirty. This helps break down stubborn stains.
  • Do pat the eraser dry with a clean, dry cloth after washing. Avoid squeezing or wringing, as it may deform the eraser.


  • Don’t use hot water, as it can melt the eraser and affect its consistency.
  • Don’t use harsh chemicals or solvents, as they can damage the eraser’s composition.
  • Don’t apply excessive force when kneading or washing, as it may alter the eraser’s shape and texture.
  • Don’t expose the eraser to direct sunlight during drying, as prolonged exposure can lead to hardening.

Bonus tip: If your kneaded eraser is sticky, you can sprinkle a little bit of baby powder or cornstarch on it and knead it in. This will help to absorb excess moisture and make it less sticky.

What if my kneaded eraser gets sticky or loses its shape?

If your kneaded eraser becomes sticky, sprinkle a small amount of talcum powder or knead it on a clean, dry cloth to absorb excess oils and restore its texture. If it loses shape, simply knead and mold it with your fingers to reshape it.
