Any advise on cleaning promethean boards?
One person has told me to just use a clean rag and wipe off the board (which i just did) but i dont think it's clean. Another told me to use cold water and u feel that's wrong. I dont wanna put chemicals on it though cause someone else told me its not safe for the boards. So please can someone give me some advice? Or tell me which one is right?
