Thankfully my kids never did this.

Gumption. I was mortified when my son did this at my brother’s house. His wife was immaculate but thankfully laughed it off any pulled out the gumption. I’m sure she”d been there before. I can’t remember what I said but he never did it again!
Maybe buy him an easle and art paper.

I guess it depends so much on the child, their age and how they react to different things. You could try designating just 1 wall they can use and make sure they know not to do it elsewhere, when out etc. but you’d have to be able to follow through with consequences when rule violated (and I guess it is a bit arbitrary why it’s ok here and not there) Perhaps you could give them special washable crayons to use and explain those are the only ones they can use; and shouldn’t draw on walls, erase anything on the wall, but maybe make a very special place, centrepiece of a wall, where you hang paper that they have drawn on to encourage them to use paper?

Interesting answers ! I most often use the magic eraser block or a bit of jif on a sponge

I would clean with sugar soap, or vodka if that didn’t work. Then I would take a social story approach and teach them what they can draw on and how walls are meant to stay clean.

There is hardly a wall or bench in our house that has not been drawn on, stamped on, or painted on (luckily that is the outside). Eraser works for the lead, and luckily my #1 likes to clean the walls, so he does it himself! If it is me, I find McLintock’s Vanilla Spray works ok. It is alcohol based.

My daughters had habit like this.i just did explain them walls are not for drawings.But after giving them unwanted papers to draw they know what to do.i always keep them on the table they can reach out for drawings.

Thick* Paint* We need an “edit comment” thingy haha

For crayon gently scrape off any think chunks then hold paper towel over it & lighty run a warm (not too hot) iron over it. Makes it melt & soak into the paper towels. If your paint is very porous it might soak into the pain a bit but you should be able to use a baby wipe to get the rest off

In Coles or Woolies you can buy “Magic Eraser Blocks” especially for this situation – easy to remove

WD40

Buy butchers paper to cover the walls or give them chalk for the driveway.

Our youngest was and still occasional is shocking for this. We were lucky enough it was mainly grey lead. Start taking the pencils or crayons away and putting them up, only giving them when they want to colour

Gumption will be your best friend and keep all pencils out of reach

Crayon can be tougher but if always try not first and lightly rub it in, magic erasers are good but they are essentially a light sand paper so could effect the paintwork.
It was hard work getting my kids to stop drawing on the walls and even now I’ll still occasionally catch the 3 year old. I make sure now to have plenty of scrapbooks around for them and write their names and things on them to make them excited to draw here instead of on my walls or furniture. Good luck!

Jif or magic eraser. Just check if not taking paint of

Try using WD-40 works really well to remove crayon on painted walls. I sprayed a little of the product onto a cleaning cloth and wipe over the crayon marks it just lifted the wax crayon off. I washed the walls after with Sugar soap all bought from Coles or Woolworths. (P.S. Do not rub hard let the WD-40 work it’s magic).

My 7yr old has Down Syndrome and still scribbled on the walls and my nearly 10yr old has a Reactive Attachment Disorder and draws occasionally on walls & furniture too.
I found a gentle clean with Jif on a sponge scourer works the best. Don’t scrub too hard as then you remove the paint from the walls 🙂
