Incidentally I would recommend not pouring a cup of lemon tea with a lot of sugar on your keyboard, just in case you were thinking of doing so

Some good keyboards may be taken apart and put in the dishwasher. Seriously!

Now, if it's a laptop you've spilled on, that can get dicier. Some folks recommend turning everything off, disassembling the whole thing, rinsing it in pure distilled water, then baking it in an oven on low heat. But all that sounds risky, and I'm pretty sure silicon is really tough to eat.

I figured that if I hit the keys hard enough it would just sort itself out. It's worked for the L so far!
