I’m an elementary school teacher. I have white boards in my classroom, large ones mounted on the walls and also individual ones. I use Thieves Household Cleaner to keep them clean. Since it is not harmful, the class can actually clean the individual ones themselves! My first graders love it. I love the fact that there is no greasy residue, the tray for holding the dry erase markers wipes clean without smears, and I can breathe the air in my room after cleaning up. Life is so much easier with essential oil products.
