Not sure about on this particular surface, but Expo whiteboard cleaner spray works like magic for old writing. I have several different surfaces at the office, including a whiteboard-painted wall, and it works equally well on all. Clorox wipes generally work really well too, but I think the Expo spray is better.

Yep, that stuff works great on these surfaces. Sometimes, you need to spray, let it sit for a few minutes, then spray again and erase. But it’ll work.
