Windscreen wipers. The basic principle hasn't changed much. But they are terrible at removing bugs, since they glide on a film of water. As I understand, the washer water is a lubricant so the wipers don't scratch the glass. Also, if water is not used, the bugs are spread in a sort of monochrome rainbow.
What I propose is a variation of the blade and pressure. Normal with water to clean the grit, then heavy pressure with some real elbow grease and a different blade edge which rotates around under the increased pressure.
So we have stage 1 which we all know, plus stage 2 heavy duty for scrubbing.-- Ling, Feb 20 2012 Dang, It's a Shame To Let Them Go To Waste Bug_20Guts_20Distribution_20System [Grogster, Feb 20 2012] Thousands of Entomophagists must be openly weeping here... pity, that.

One person points at it and says to the other: "I bet he doesn't have the guts to do that again!"-- Vernon, Feb 20 2012 random, halfbakery
