A dry erase eraser is very effective in keeping any whiteboards clean. But after some time, the dirt tends to accumulate in the eraser, making the effectiveness greatly affected. You can either buy a new one or clean the eraser to make it more effective again. But how to clean dry erase eraser? Please check different methods below on how to do it effectively.

Method 1: Using a Mild Detergent and Brush

What You Will Need:

  • Mild detergent, brush, water

Step 1: Initial Cleaning Using a Brush

The initial step is to remove particles that have accumulated the dry erase eraser. This step can be done using a soft brush that can effectively remove all the larger particles and dirt stuck on the eraser for a while.

You can start by brushing the surface very slowly and lightly. You should use a soft-bristle brush for this step to prevent the brush from damaging the surface. Brushing can be done by using a back and forth motion but make sure to cover the entire surface of the brush.

Step 2: Deeper Cleaning Using Mild Detergent

Once the dirt particles are removed, it is time to do a deep cleaning to remove every dirt found in the eraser properly. You can use a mild detergent and mix it with water to make a cleaning solution for the dry erase eraser.

Then, you can start dipping the brush into the water mixture while using it to scrub the felt. You can do this step by starting at the top portion to the bottom while scrubbing in circular motions. Doing this way will remove all the possible dirt that remains on the eraser. After that, you can start rinsing the felt entirely with cold water.

Step 3: Removing the Excess Water and Drying

The next step is to remove the excess water from the eraser. You can do this step by pressing the duster on a tower. You can repeat this process several times until the water is eradicated from the eraser.

You can now let the felt air dry completely to complete the cleaning. Once it has dried, you can again use the brush to remove any particles or dirt that remains after the cleaning process to maximize the result.

Method 2: Through the Use of a Garden Hose

A garden hose is a unique way to clean a dry erase eraser. It is an unconventional method but is also very effective.

What You Will Need:

  • A garden hose

Step 1: Choosing the Right Location

The initial step is to find an excellent location for the cleaning. Since you will be using a garden hose, expect a lot of mess during the cleaning process, especially water. So, it is a must to choose a location that is near your water supply for easy access.

The ideal place should also be on a patch of grass to reduce the messiness and the unnecessary flow of water to the ground. If you have a lawn or backyard with grass, that is perfect for cleaning the dry erase eraser.

Step 2: Cleaning the Eraser using the Hose

The next step is to clean the eraser using the hose properly. We will be using the water pressure to remove all the dirt particles found in the eraser. Start by putting the hose on the ground then spraying them using the hose.

Now, if your hose comes with multiple settings, the better. This feature will allow you to choose the highest possible setting to produce greater water pressure. The higher the power, the greater the chance for the water to penetrate the cracks of the eraser and remove all the ink particles accumulated on the eraser over time. You can continue spraying until the water runs clear and all the ink is removed.

Step 3: Drying the Dry Erase Eraser

After cleaning the eraser, the next step is to dry the eraser completely. You will need to find a place where there is a presence of sunlight. Once you have the place, you can place the dry erasers directly in the sunlight to let it dry.

It will probably take about one to two hours of direct exposure to sunlight for the eraser to completely dry. As a reminder, make sure not to use the eraser if it is still not dry. If the need to extend the exposure to the sunlight is needed, then do it immediately until the eraser becomes fully dry.

Method 3: By Using a Toothpaste

Another unconventional way to clean a dry erase eraser is to use toothpaste. Yes, a toothpaste known for cleaning our teeth can also be used to clean dry erase erasers. Check below for the step-by-step process.

What You Will Need:

  • Toothpaste, wet cloth, running water

Step 1: Toothpaste Application

The initial step is to apply the toothpaste to the dry erase erasers. If you are wondering, toothpaste has these slight abrasive cleanser properties, making it practical to clean some surfaces, such as those found on dry erase erasers.

In the application, you can put a line of toothpaste to the bottom of the eraser. Make sure to put just enough amount to cover the surface on the bottom of the eraser. Spread it slowly to avoid wasting the toothpaste.

Step 2: Scrubbing and Cleaning the Eraser

The next step is to scrub the eraser using a wet cloth. You can start scrubbing the eraser using a damp cloth in a circular motion. You will also need to spread the toothpaste evenly across all the eraser parts.

But you must understand that in doing it, there is the tendency that the ink removed from the eraser will likely stain the wet cloth you are using. So, make sure that the cloth is of no use from your end.

Step 3: Rinse with Running Water and Let it Dry

The final step is to rinse the eraser with running water to remove all the ink particles that remain on the surface. Using a hose with running water can help in removing dirt. If you have an adjustable hose, use the highest setting to allow the pressure to clean the eraser thoroughly.

Then, allow the eraser to dry after. You can find a place with direct exposure to the sun. You can expose the eraser to the sunlight for one to two hours until such time that the eraser is completely dry.
