Maple syrup or corn syrup stains should be removed as soon as possible. Begin by using a blunt kitchen knife to remove any excess syrup still on the fabric. For washable fabrics, spot treat the stain with a bit of liquid laundry detergent and then wash as recommended on the garment label.
If the garment is dry clean only, point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
