Summarize the following:
Squirt some grease-cutting dishwashing liquid onto an unused toothbrush. Scrub the stained area that the crayon wax left behind. Wipe up any remaining suds with a cloth dampened by water only. Let the car seat air dry. Put a couple of drops of a dry cleaning solvent, such as Guardsman, onto a clean cloth and then lightly dab the stained upholstery. Add a little more solvent to the cloth if you don’t see progress. Then, let the car seat air dry. Do a test on an inconspicuous part of the upholstery beforehand to make sure it’s suitable for your particular type of upholstery. Cover the stain completely with baking soda. Let it sit for at least a half an hour or so, and then vacuum it up to remove the stain. Repeat this process if the stain remains. If you have crayon stains left behind on your leather car seats, put a little rubbing alcohol on a clean cloth. Wrap the cloth around your finger and apply some pressure while you rub at the stained area. Then wipe the area with another cloth lightly dampened with warm, soapy water. Finally, wipe the area with a clean cloth dampened with water only and then let the spot air dry. Make sure to use a mild soap to make your soapy water.
Scrub stained upholstery with dish soap and a toothbrush. Blot stained upholstery with dry cleaning solvent. Sprinkle baking soda on the stained upholstery. Apply rubbing alcohol to stained leather.
