Coke for blackboards

A totally frivolous post with no real purpose, but walking to a meeting this morning I watched someone cleaning a blackboard outside a pub with a cloth dipped into a glass of coke or cola. Curious as ever, I had to ask why. The guy cleaning informed me that coke was the best cleaner there was, much better than water, and "helped preserve the integrity of the blackboard paint". Well I didn't know that - I really do learn something every day, but is it true? Luckily not many people use blackboards in the UK these days - can you imagine the mess had all teachers done this? (I don't think the ice is obligatory!)

If it does this for blackboards - I do wonder what it does to teeth?
