You know after you reheat spaghetti or soup in the microwave, inevitably there will be tomato-sauce splatters and carrot chunks spewed all over. Every once in a while, you’ll think, "Oh, I’ll wipe the mess up later. I’m starving." But, later never comes, and the red sauce turns crusty and is almost impossible to clean up. Here’s a simple solution: Cut a lemon in half, place it in a bowl of water, and stick the bowl in the microwave. Turn it on for about a minute or two. The steam of the lemon water will hydrate the crusty food, which will make it easier to wipe clean.
