If that was in response to my post, I don't see how I said or implied that.

What I should have added was that the wet method should be used when a blower/brush isn't enough.

Other methods are certainly possible (ultrasound anyone?), just that I've successfully used the washing method many times to remove gunk more serious than dust from a focusing screen.
