How do you clean the walls with full of (crayons) drawings?

I agree with the vinegar and baking soda. I've read that in an article before. My mom tried it too sa walls namin in our ancestral house and it's really effective.

I have only tried using WD-40. You can also check this link for suggestions: http://www.rd.com/home/cleaning-organizing/how-to-get-crayon-off-the-wall/

I agree with the vinegar and baking soda, it works wonders! Though, you can also try using hot water if the marks are particularly hard to take remove.

Scrub a small amount of non-gel toothpaste using an old brush on the scribbled wall and rinse it with damp cloth.

The best ang white vinegar and baking soda. Tanggal agad isang hagod pa lang.
