Since I haven't mentioned it for a while, I had the best results with the old "Weber Costello Markerboard Cleaner",

(Octylphenoxy Polyethoxyethanol (Triton X-100) and Trisodium Phosphate) which is photoflow and a surficant.

then they changed the formula to make it 'green' :-(

Bought a few ingredients (Triton X-100 and Ethylene Glycol) but haven't tried making anything.

What you want is a lubricant and a cleaning agent that will take off any gunk on the surface without softening the binder.
