WARNING:  THIS CLEANER IS FLAMMABLE AND ITS USE REQUIRES
SUBSEQUENT REAPPLICATION OF RAIN REPELLENT.

NOTE:  If hardened rain repellent stains remain on the windshield or windows after normal washing, these may be removed with a repellent remover pad or by hand-scouring with a mild detergent solution and a plastic abrasive pad such as nylon knit over a foam core. Hand polishing with an optical grade polishing compound allied with a wet outing flannel cloth may be used as an alternative method. Rinse the window with clean tap water after using either method.
Do not use the optical polishing compound with the plastic abrasive pad. Do not use household grade abrasive cleaners because of uncontrolled grit size.
(d)  Close all window electrical heating circuits.
