Removing Pine Tree Sap From Glass?
Have you tried soaking the glass with Skin So Soft Bath Oil from Avon? It works on just about anything sticky. Soak it really well and scrub with a soft cloth. It may take a while and some elbow grease but it should work. Good luck! Yilbit
Removing Pine Tree Sap From Glass?
Just thought of something else for removing the sap. WD-40 may work? Never tried it but I have heard it removes tree sap from other surfaces.
