This powerful summer windshield washer fluid handles common hard to handle obstacles.
 
Bugs and Bird Droppings: 
Carbohydrates found in insect parts and bird droppings cause the biological deposits to stick to windshields on impact.  Prestone’s patented formulation penetrates biological deposits to break down and emulsify them.  The formula digests the deposits so they are easily removed from the windshield by the washer fluid and wipers.
 
Tree Sap:
Normally insoluble tree sap is solubilized by the chemical action of the formulation.  The tree sap is softened, emulsified and rendered easy to remove.
