How do I remove melted crayon from car upholstry?
Handle this the same way you would if you got crayon on clothing. Put a cotton rag over the damaged spot, and then iron it. This will melt the crayon and most will be absorbed into the rag. Use a fairly low setting on the iron because most vehicle seat fabrics are synthetics and will melt if heated. You might want to test this on a location in the car that is not easily visible first, in case the iron melts the fabric. This should remove the bulk of the crayon from the fabric.
