Most children see themselves as the next Michelangelo at some point, and decide to grace the walls of their home with a mural. They may also leave their crayons in a clothes pocket, only to melt in a hot washer or dryer. Or else they leave crayons on the car seat in the summer, creating a gooey mess that sticks to the car upholstery. In other words, crayons can provide children hours of diversion and pleasure, but create headaches for parents. It is possible, however, to clean up the waxy crayon mess.
Put pieces of crayon-stained clothing in the freezer, or chill the area with a plastic bag full of ice, then scrape off the hardened wax with a butter knife. Dab the area with stain remover or dry cleaning solvent, then rinse with water. After applying detergent directly to the stain, launder the clothing in the hottest water that is appropriate for the fabric.
Scrape the wax off an item of clothing and then place the area between two paper towels. Place a warm iron over one of the paper towels and press. Remove the paper towel from the back of the fabric, and dab on some stain remover or dry cleaning solvent and let dry, then launder the item in the hottest water the fabric can handle.
Remove any remaining stains by washing the garment with chlorine bleach added to the load, or by soaking in oxygen bleach. Do not place the item in the dryer until the stain is removed or it will set.
Remove stains from of a whole load by washing the clothing in the hottest water appropriate for the fabrics with washing powder and 1/2 cup of baking soda.
Remove crayon from upholstery by dabbing the stain with dry cleaning solvent, testing the solvent first on an inconspicuous place. Do not use on leather, suede or vinyl. Rub any nappy fabrics along the pile.
Take any leather or suede items to a professional cleaner. Rub liquid washing powder or a paste of powdered washing powder and a bit of water onto vinyl items to remove crayon wax.
Scrub crayon off painted walls with toothpaste or a cloth soaked with ammonia. Rinse the cleaned spot and dry.
Apply a paste of cornstarch and cleaning fluid to crayon wax on wallpaper. Let it dry and then brush it off. Repeat as necessary until the stain is gone.
