Soak a soft cloth with rubbing alcohol, and blot the sap from the fabric. Blot the sap from the edges of the stain to avoid spreading the sap. For a large area or thick sap, pour the rubbing alcohol directly over the sap, and work the sap off the fabric with your fingers.
Wash the cloth normally with detergent and warm water, and rinse the fabric. Repeat the process until the stain disappears.
Put the fabric in the dryer, and run a dry cycle. Remove the fabric from the dryer once it is dry.
