I was helping set up for a workshop and noticed that the white board we were going to use had a lot of information that had been on there for months. I first tried a chemical cleaner, which didn’t do much to take off the marker and boy did it smell awful! I then remembered I had a small bottle of peppermint and orange essential oil mixture under the counter. I put several drops all over the board and the old ink came right off with very little rubbing needed. The best part was the office then smelled wonderful and we got a little lift from the scent as well.
