You didn't say if it was cloth or leather, but for this case I will assume we are dealing with a cloth seat. Their are two options. The first one is easier, any wiould most likely work The second is the way most professional detailers correct this problem, but it is more involved, and can damage your seat if not done correctly, so here are both methods.
Method 1: First off on the dried left over crayon wax, I would try the old ice cube trick, as where you use an ice cube to freeze the wax, and chip it off with a brissle brush, or a finger nail. Next, mix two tablespoons of laundry detergent (Tide) with a standard spray bottle of water. This is the same basic chemical composition as Oxy-Clean. Shake the mix up, and spray directly on the problem spot. Next, scrub with the brissle brush till the stain dissapears. Note, This ice cube trick also works on gum in your carpeting.
Method 2: This method requires a couple of white terry cloth twels, and either a heat gun, or clothes iron. You lay two rags over the trouble area, and apply heat. The wax will melt, and both the wax, and dye color should lift into the rags. Then follow up with the spot removal method mentioned above.
Either of these methods should resolve the problem, however after doing this procedure, your stain is still a problem, then their are more tricks we can try. If you have any further questions on either this, or anything related to detailing, either post them here, or you can reach me at firstname.lastname@example.org.
Good luck, and Happy Detailing!
