This might be the paint for you. I was in Sherwin-Williams picking up paint for the house over the weekend and discovered this display while I was waiting:
This is the first time I’ve seen this paint, but they had a display set up in the store where you could write on it with marker and clean with water and a paper towel to see for yourself.
Worked just like they said. (Excuse the shadows and bad phone pics.) The Duration paint side wiped off easily, but I’m wondering how soon you have to get to the marks or if it would still wipe off after several days/weeks.
It is a little pricier than regular paint, but as someone who’s had chap stick, Sharpies--and worse--on her walls, I think it might be worth it, if it works.
Have you had any experience with Duration paint?
If not, just tell me something funny/gross/etc. your kids have done to your walls. I could use a good laugh :)
