    The most common sources of compressed air are cans of compressed air and hand pumps or squeeze bulbs. The main criteria for compressed air sources is the air must be clean and dry. This is one reason why blowing on the lens is not recommended. Compressed air will be able to clean 90% of lens so try using compressed air first.
