Prepare and Gather the Right Supplies
Before you start cleaning your whiteboards, it is essential to have the right supplies in your arsenal. One of the key ingredients is isopropyl alcohol because this effectively removes stubborn marks without damaging the surface.
Additionally, a soft, clean cloth, such as a microfibre cloth, is ideal for wiping the board. If you are trying to figure out how to clean a whiteboard with old marker on it, water and mild detergent may also be necessary, and a spray bottle can be handy so you can apply the cleaning solution evenly.
Once you have your supplies ready, it's time to prepare the whiteboard. Start by erasing any fresh dry marker marks with a whiteboard eraser, which prepares the board for deeper cleaning. For stains or permanent markers, make sure you write over them with a fresh dry-erase marker, let it dry, and then erase it, as this method effectively lifts the stubborn marks from the surface, making them easier to clean.
