Clean the surface to be sprayed with dirty grease, Shake the bottle vigorously about one min. before use. hold the bottle 20-30cm from the surface to be sprayed, Spray the lens every 5 min. Repeating 1 to 3 times with a thin layer each time to obtain a better effect, Turn the bottle over and spray several times until gas comes out to clean the button.
