With company coming and going during the holiday your microwave may get a lot of use and dirty too. You know that some ovens are self-cleaning, but what’s this about microwaves? It’s true – you can let your microwave do the job for you by heating up some water and lemon juice or vinegar in a microwave-safe bowl for five minutes, letting the mixture sit to cool, and then wiping down the sides. Any built-up grease and grime will be long gone, without you wearing yourself out.
