What is the best way to clean a microwave oven?
I’m afraid that if you’re hoping for a “magic cleaner” that will make it easy, there isn’t one. One way is to 3/4 fill an old Pyrex bowl with hot water, and a generous squirt of washing up liquid. Put the bowl in the microwave, and then run the microwave for 10 to 15 minutes on full power. When it’s finished heating the water leave it to stand for 5 minutes, then clean the oven cavity with an old dishcloth or flannel rough but not abrasive after all the steam this will have generated, any baked on food deposits should have been softened and be easier to remove. There are some microwave oven cleaning sprays, and liquids, as well as microfiber cloths for stainless steel on sale (we sell them in our shop and online). These are good, but you still need to use a bit of “elbow grease”.
