My teacher eats about 10 pounds of chalk every day (he's a math teacher). He's always using the chalk board. He has tried everything from rubbing the eraser all over it, using WD 40, and his very own patented rag with cooking oil to try to clean it, but nothing seems to work. Does anyone know of a sure way that will clean the board well enough (it has to be simple because he has to do it often) to use?

Well eating chalk is the hazards of the job. back in the day, yearly, the boards were cleaned with water THEN they were smeared solid with chalk (like with the chalk on it's side) and erased. Then what was written would erase.....

Yes! I do this everyday at work. I am a custodian at a college and to clean them you take a wet towel and wet the board pretty well not too much, and then take a window squeegee and squeegee it off and the board will dry nice and black. By the way...don't put anything else on it. You may have to scrub off the wd-40 for it to be really clean.

put water in a bucket with just a little bit of soap and a sponge run the sponge horizontally over the chalk board to reduce smears dont use too much soap

Umm..try lime juice? I don't know..chalk is calcium carbonate and an acid will just break it down to a salt and carbon dioxide and water..haha.

I've heard that the microfibre cleaning cloths (dry) work very well on chalkboards.
