To make the eraser soft, pour approximately a quarter cup of warm water into a bowl. Place the bowl on a table or other elevated flat surface. Soak the eraser in water.

Softening Procedure

When you first obtain a soften kneaded eraser, it is never ideal to use it easily. It would help if you softened it appropriately before making it suitable for future usage. A soften kneadable eraser is useful for more than just erasing pencil markings.

It is a versatile medium in the arts and sketching, with several applications in pencil and charcoal works. You may reshape the eraser to your liking and make it a great service.

Step 1: Remove the plastic wrap from the kneaded eraser. Shove the eraser with your finger. Please make certain that you are not too tough on them straight away.

Step 2: When pressing the eraser to make it softer, break a piece of the eraser. The quantity should not exceed one-quarter of the total body weight. There is no requirement to take that particular element, although it is advisable to work further.

Step 3: Begin carefully pulling them out using the 1/4 part of the kneaded eraser. Even if you break it, you may easily reattach them and continue doing your procedure.

Step 4: Once the body of the eraser has been sufficiently softened, form it into a ball shape. 

Step 5: Roll the eraser ball over your palm. It softens and smoothes the eraser’s whole surface.

Furthermore, you can reshape the eraser more easily and rapidly. With your hand, feel the suppleness of the ball. Remember to keep the eraser’s elastic property, one of its greatest qualities.

Step 6: Press the ball with your hand on a flat surface. It will completely flatten the ball and prepare it for additional stretching, softening it.

Step 7: Once the eraser has softened and flattened enough, rip it into pieces. Reassemble the fragmented fragments and combine them into a single sample. You’re ready to start working with that item that will be gentle and efficient enough to serve you well.

Softening using spray silicone

Step 1: Spray silicone spray on the rubber. This spray is available at any camping supply shop. Spray until the rubber is completely saturated. Place the rubber in an airtight plastic bag. For large chunks of rubber, use large waste bags.

Step 2: Place the rubber in a plastic bag and store it for three to seven days.

Step 3: Lift the packed rubber piece and bend it to test its flexibility. When the necessary suppleness is achieved, take it from the bag and use it. If the rubber hasn’t softened to your liking, you may need to repeat the operation.

Use of heat

  • In a stew pot on the stove, heat some water. Please bring it to a boil.
  • Place the stew pot in the sink and soak the rubber in water to soften it.
  • Remove the rubber from the water using a salad or canning tongs. Put on a pair of oven mitts or leather work gloves if you need to contact the rubber at this stage.

If you leave a kneaded eraser inactive for an extended period, it may dry out. However, it does not remain in that condition indefinitely. With the right measurements, you can immediately determine their hardness. Remember that no obstacle or challenge may deter your enthusiasm for drawing and sketching because every problem has the best solution. 

The soft and pliable eraser takes pencil and charcoal markings off the paper without disturbing watercolor or other colors. While kneaded erasers may be used for years if properly cared for, this does not guarantee that they will last forever. Because of their flexibility, they are useful for various uses and tasks.


1. Why are Pink Erasers Used?

Old school erasers were constructed of a combination of rubber and pumice, with the pumice providing enough friction to allow the pencil markings to be erased. The hue was well received by consumers, which led to the production of a pink eraser in 1916 named “Pink Pearl.”

2. Are Pencil Erasers Reusable?

If the rubber is synthetic, some erasers last longer than others. The worst culprit is sunlight. UV rays are harmful to rubber and may transform an average pencil eraser into dust in less than a week!
