How to Make Kneaded Eraser Softer

How to Make Kneaded Eraser Softer

A good kneaded head eraser comes with a rubber material that’s usually synthetic. This can then be broken up and turned into pieces of eraser putty for erasing pencil marks. One of the challenges that people find when using these pencil erasers is that they eventually get too hard and become a solid eraser which makes them more difficult to use.

This post includes steps that you can take to maintain the softness of a new kneaded eraser to keep it effective and easy to use and avoid a super crumbly eraser.

How to Make Your Kneaded Head Eraser Softer

  • Unwrap the dry-kneaded eraser from the plastic and press on it with your finger.
  • This will make the rubber eraser soft.
  • Make sure to take around 1.4th of the softer putty part from the whole eraser.
  • Once the kneaded eraser soft, turn the kneadable eraser into a ball shape. 
  • Roll it in between your hands to make sure the rubber eraser surface is smooth and soft. 
  • You can make sure that you don’t end up with a crumbly kneaded eraser by smoothing it out in the palm of your hands and ensuring that it remains elastic. 
  • Next, put the ball-shaped kneaded eraser on a table and use your palm to apply pressure to the putty eraser until it’s flatter. 
  • You can then gently stretch it to see if it keeps its elasticity. 
  • If it isn’t soft at this stage, apply a small amount of warm water with a wet kitchen sponge to the mediocre kneaded eraser and repeat the steps of rolling it into a smooth ball and flattening it out. 
  • When you’ve turned your solid erasers into soft erasers, break them up into small pieces that you can use as clean eraser material. 
  • If there are eraser crumbs leftover, simply wipe them away.

We hope that you’re feeling more assured about turning extremely crumbly kneaded erasers into softer ones. However, if you’ve applied the above steps multiple times and it hasn’t worked, it’s likely that the eraser is too old and needs to be replaced. 


Why do kneaded head erasers get harder?

One of the main reasons why you end up with hard or somewhat crumbly putty is because they become worn down after erasing graphite marks from free drawing and writing. Following the above steps will ensure that you can maintain the elasticity of your kneaded erasers so that they’re no longer stiff and last longer in your art supplies.
