Getting crayon off a wall can be a bit of a hassle, but it's definitely doable! A common method is to gently rub the marks with a damp cloth and some baking soda, as the mild abrasive can help lift the crayon without damaging the paint. Magic erasers are also effective for tougher spots. Have you tried any methods already, or is this your first attempt? Is it a large area that needs cleaning, or just a small section? I'm here to help!
