Blair; I have a white board in my office that has had notes on it for at least the past 6 months. I just attempted to clean it after reading your post, and I can see your frustration. I was able to clean off the old stuff with stamp pad ink reactivator. It worked great compared to alcohol, or window cleaner. It's nasty stuff though - Flammability = 3, Health = 1, Reactivity = 0, Personal Protection = B. I'm not sure waxing would be a good idea, it may prevent the dry erase markers from writing on it at all. Maybe a small test spot in a corner with your favorite wax would be a good test. My favorite window cleaner is Rain-X. It will provide a protective film that makes rain bead up and run off. Maybe you can test it on a corner of one of your boards. I've found it at most auto supply stores. I usually buy the concentrate and mix a capful with a quart of water. Good luck!

We have a training / breakout room with large white boards on the walls. The standard cleaner works OK for removing the markings left on for days or weeks, but some still remains. Is there a better cleaning solution (not likely, you would think that the experts in white board markers would know how to remove this stuff if it sits dried for a while) that will clean these boards? Second question - can the white boards be waxed periodically to improve their cleaning performance? What type of wax would be best?
