There is no other product for use on glass which will give the brilliant clarity of Tri-Wash® & Protective Glaze. The glass will seem to disappear. The product also makes a glass surface smoother, or slippery, so that water runs off a windshield without a trace. This “slick” surface also means that insects, bird droppings and tree sap can be removed effortlessly. In winter, windshields and outside mirrors protected by Tri-Wash® & Protective Glaze are more easily cleared of snow and ice.
