*DISCLAIMER: These white tops are plastic and NOT the same material composite as a true whiteboard, which is generally of a porcelain and glass composite.
Alcohol-based markers work best, but always test a small patch first to ensure it can be erased. Please test every colour you intend to use. Every brand uses different pigmentation in its colours, so some colours may not wipe 100% clean.
In the event that there is ghosting after erasing, simply add a few drops of hand santiser and rub gently to remove any stains. Or, use vinegar diluted with water in 1:1 ratio.
