Ask HN: How dirty is your keyboard?

My IT guy (I'll call him Deeter) walked in my office wanting to do an important security fix on my box. He jumped a foot in the air when he saw my keyboard. "Um, Wow, Dude," he said, hiding his hands behind his back. "That's a lot of crumbs. You must eat over your keyboard?" Yeah, it's true. I eat at my desk. Sorry. And yeah, my keyboard has some grime. And, well, perhaps a significant amount of crumbs. But not enough to make a rice cake. What's the prob? Is this really a sanitary issue? Anyway, Deeter refused to touch it. He left my office, suggesting I open a ticket and ask for an entirely new keyboard. . .
