White-Board Cleaner

I'm wondering if anyone has ever been able to find a food grade white board cleaner. We use white boards throughout our facility and many staff have inquired about a liquid or a cream cleanser. I would appreciate any suggestions.

If you've gone to the trouble of a white board cleaner, perhaps you could also recommend a safety glass cleaner.

Thanks

have you tried using ethyl alcohol solution?

Why would a food grade cleaner be required?  There is no requirment that such a cleaner should be food grade.
