Apply rubbing alcohol or hydrogen peroxide.
alcohol and hydrogen peroxide are some of the most effective solutions for removing stains from a whiteboard, as they help remove chemical residue. Mix either rubbing alcohol or peroxide (not both) in a 1:1 ratio with water. Apply the solution to a microfiber cloth, then wipe the board clean.
- For the best results, use 90-99% isopropyl alcohol. Lower percentages will also work, though it may take marker.a bit more effort.
- For stubborn stains, apply the alcohol or peroxide directly to the area. Let it sit for a few seconds before wiping it away.
- a “mixture that is 50% tap water and 50% isopropyl rubbing alcohol” is effective at removing the “phantom remnants” of old dry erase
Try hand sanitizer.
Most hand sanitizers contain at least 60% isopropyl alcohol, meaning they can effectively clean whiteboards. Apply the sanitizer directly to the whiteboard and use a soft, clean cloth or paper towel to wipe it over the entire surface. Let it sit for about 30 seconds, then wipe it off with a fresh cloth or paper towel.
- Because hand sanitizers generally have a lower percentage of alcohol, this method may take a bit more effort than using alcohol directly. Repeat the process as needed until the board is clean.
- Non-acetone nail polish remover can be used in a similar way.
“When whiteboard cleaning products purchased in a store leave behind ghost remnants, you can use nail polish remover, hand sanitizer, or rubbing alcohol to get the job done.”
Make a vinegar solution.
Vinegar is a safe, non-chemical way to clean a whiteboard. For light stains, mix 1 tsp (5 ml) of white vinegar per 1 cup (236 ml) of water. If you think the stain will be stubborn, mix the two in a 1:1 ratio. If desired, add a drop of dish soap, as well. Pour the solution into a spray bottle and spray the white board. Let it sit for a few minutes, then wipe it away with a clean microfiber cloth. Repeat as necessary until all the stains are removed.
- Adjust your vinegar to water ratio as necessary until you find what works best.
Spray on some hairspray.
Hairspray typically contains isopropyl alcohol, so it can be used to clean whiteboards, though it may take a bit of effort. Spray the surface with the hairspray and let it sit for a few minutes. Then, dip a soft cloth into a mix of warm water and gentle detergent (like dish soap) and wipe the board. This should remove both the stains and the sticky residue left by the hairspray
