For a more gentle option, use an art gum eraser.
If you aren’t sure whether or not your wall is washable, try out your dish soap and water combination on a discreet corner of the wall first. If the paint or wallpaper seems fine and it doesn’t wipe off any color, then you’re good to go. If the soap and water makes your wallpaper or paint flake off, stop using it right away, and try a different method.
Make sure the toothpaste is white—otherwise, it won’t have the stain-fighting power that’s needed to remove pencil marks.
Baking soda is mildly abrasive, so it does have the potential to damage wallpaper or non-washable paint. If you aren’t sure whether or not your walls are washable, try using the baking soda in an inconspicuous spot on your wall. If the paint flakes off or you notice any color transfer onto your cloth, pick a different method.
Eraser sponges are the perfect choice if your kids used both graphite pencils and colored pencils. Eraser sponges are not a good option if you have wallpaper, since it may cause the wallpaper to peel.
Dough cleaner is also great for non-washable paint.
