I just started work as a lab assistant in a chem lab. The whiteboard the instructor uses for classes gets very dirty very quickly. The woman who started at the same time as I did spent over 3 hours scrubbing it with a solution of a powdered soap-like product in a milk-carton style container to get it anything like clean.
I'd rather not watch her do that again (or, worse, do it myself). Can I make a better cleaning agent without using too much of an expensive chemical?
So far I've seen large quantities of Ethanol, Acetone, Alcohol, and milliQ water. What else we may have, you folks would probably know better than I.
