A clean whiteboard is essential for clear and effective communication in any setting, whether it be in the classroom, conference room, or office. 

It’s important to keep the whiteboard in good condition, especially if it’s an old one that’s been frequently used over time. 

In this article, we’ll go over the steps to effectively clean an old whiteboard and keep it looking as good as new.


Before we get started, let’s gather the necessary materials. You’ll need: 

  • A whiteboard cleaner
  • A soft cloth or paper towels
  • Warm water
  • A bucket

It’s important to avoid using abrasive materials that may scratch the surface of the whiteboard and to be careful not to use too much water as it may damage the whiteboard or the wall behind it.

Step-by-Step Cleaning Process

  1. Dry-erase the whiteboard: The first step is to dry-erase the whiteboard as much as possible. Use a soft cloth or paper towel to remove any residual markings.
  2. Apply whiteboard cleaner: Next, you’ll want to apply the whiteboard cleaner. You can either spray or pour the cleaner onto the whiteboard and then spread it evenly with a cloth or paper towel.
  3. Wipe down the whiteboard: After the cleaner has been applied, wipe down the whiteboard using a soft cloth or paper towel.
  4. Rinse with warm water: Fill a bucket with warm water, and dip the cloth or paper towel into the water. Then, wipe down the whiteboard to remove any remaining cleaner.
  5. Dry the whiteboard: Finally, use a soft cloth or paper towel to dry the whiteboard thoroughly.


To keep the whiteboard in top condition, it’s important to clean it regularly. Depending on how frequently the whiteboard is used, it may need to be cleaned once a week or even more often

In between cleanings, it’s a good idea to use a whiteboard eraser to remove any markings, and to avoid using permanent markers that can damage the surface of the whiteboard.

Cleaning Old Whiteboards Vs New Whiteboards

The main difference between cleaning an old whiteboard and a new one is that over time, old whiteboards can become stained or have built-up residue that is more difficult to remove than fresh markings

When cleaning an old whiteboard, it’s important to be extra careful not to scratch or damage the surface. You may also need to use a cleaner that is specifically designed for removing stains or built-up residue.

In addition, when cleaning an old whiteboard, it’s important to consider the type of surface and the type of cleaner that you’re using. Some whiteboards are made of porcelain or other delicate materials that can be easily scratched, while others are made of more durable materials that can withstand more aggressive cleaning methods. 

Make sure to choose a cleaner that is appropriate for the type of whiteboard you’re cleaning, and follow the instructions carefully.

It’s also important to be mindful of the environment when cleaning a whiteboard. Some cleaners contain chemicals that can be harmful if inhaled or come into contact with the skin. 

Make sure to follow safety precautions, such as working in a well-ventilated area and wearing gloves if necessary, to protect yourself and others.

Overall, cleaning an old whiteboard requires a bit more care and attention than cleaning a new one, but with the right tools and techniques, it can be done effectively.


In conclusion, cleaning an old whiteboard is a straightforward process that can help keep it in top condition for clear and effective communication. 

By following the steps outlined in this article, you’ll be able to keep your whiteboard looking as good as new. 

So, why not take a few minutes today to give your whiteboard a good cleaning and enjoy a clean slate for your next meeting or presentation?
