Tree Sap, Pitch and Resin Removal in a StingRay Parts Washer
Tree sap is difficult to remove from parts, but with a StingRay parts washer and the StingRay Power Wash Process, this can be accomplished in short cleaning cycles with the proper detergent and heat.

Sap: More of a liquid, like honey or less viscous than honey. Sap is the sugary secretion from plants and trees. Pitch: Intermediate between a liquid and a complete solid. Pitch is like that crystallized honey you find in your pantry after it’s been there for quite a while. Resin: Most solid of these forms. If you’ve played an instrument with a bow (like the violin), you’ve probably used a solid block of resin on your bow. People seem to use “pitch” and “resin” more interchangeably, while sap usage is reserved more often for the seeping, liquid form. |
