Kids will be kids. And kids with crayons are little chaos machines that are bound to mess something up. Now this scenario may be common inside the classroom but they might happen at home.

A quick way to do this is to use scouring powder to scrub away those ugly crayon marks. Now the blackboard paint is tough enough not to be damaged by the scouring solution.

But here’s an ingredient to make home-made scouring solution:

1. 1/4 cup borax
2. 1/4 cup baking soda.
3. 1 1/2 cups hot water.
4. Stir until mixed.
