Avoid crayon wax stains with parchment paper
Keeping kids occupied in the car with crayons and a coloring pad is commonplace, but it can sometimes cause stubborn stains on seats, especially with Melton crayons. An effective remedy is to place a piece of wax paper over the stain and run a hot iron over it. This lifts the wax, making it easier to clean later with a product suitable for upholstery. In this way, you can keep your car clean, while allowing children to play safely.
