I have a can of Endust Compressed Gas Duster on both floors of my house. There is a million uses for this product. Not just cleaning the crumbs out of your keyboard. It's great for dusting small knickknacks. I use it to clean the tracks of the sliding glass doors. It gets the crumbs out of the toaster, beside the stove and the counter tops. It cleans car vents, wall air condition vents, fan blades. It's convenient and easy to use. The nozzle never clogs. Due be sure it use short quick bursts of air otherwise the can will get frosty on the sides.
