The method you will use to clean off chalk will depend on where the chalk is. Sidewalk chalk can be washed away from sidewalks with a hose.
just simply use rain water with a sponge and gently scrub the liquid chalk off.
Re-paint it with chalkboard paint, cheap and simple.
If you erase the board, then use a wet paper towel to remove the rest of it, you'll have a sparkly board ;)

The Luhya translation of the English words 'chalk board' is "lisisi lie ichoka".
Chalk is used on the black board because chalk is easy to write with on a black board.
Nature's chalk is limestone--hard. Blackboard chalk is soft--gypsum.

It would be an insulator- chalk board erasers normally consist of two parts, a wooden handle and a soft pad that wipes off the chalk from the board. Neither of these parts are conductors of electricity.
Chalk is Calcium Carbonate, aka CaCO3, so it's only one substance.
because it consists of small particles that are similar to liquid. Even if we add water to a powdered chalk, it dissolves easily whereas a lump of chalk is harder to dissolve in water.
