Canon EF-S 17-85mm f/4-5.6 IS USM clean dust from the inside of the lens

This video is about clening the dust from the inside of a Canon EF-S 17-85mm f/4-5.6 IS USM lens. Actually this method works on many other Canon lenses also.
As you zoom in and out, the air goes in and out to/from the lens, and due to this the lens collects dust inside. Mostly the dust is between the front lens and the second lens element. So I'll show you how to remove the front lens element, remove the dust and clean the lens elements, then assemble the lens. Fortunately, the front lens can be removed very easily, don't need to disassemble the whole lens.
