Boil some water, then put the boiling water in a shallow bowl and cook it in the microwave for about 10 minutes. Make sure it doesn’t boil dry. Having steaming water in your microwave will loosen the pieces of food that are stuck on the inside of the microwave. After 10 minutes, take the boiling water out of the microwave. Don’t forget to wear your oven mitts as the bowl will be (literally) steaming hot. Wipe down the inside of the microwave with a damp cloth, don’t forget to do the roof of the microwave. It should clean easily, but if it doesn’t you may need to repeat boiling the water for another 10 minutes.
While you have a damp cloth in your hand, wipe down the outside of the microwave and the microwave door.
You can also put a slice of lemon or some lemon juice into the water which will help with loosening the stuck pieces. Alternatively you can use vinegar in the water instead of lemon juice.
The more often you clean the microwave, the less work it will be each time you clean it. If you wipe down the microwave each time you use it, food won’t get stuck inside. You can avoid food getting on the inside of the microwave by always cooking food covered.
If you have a steam cleaner you can use that, although I find that cooking the water in the microwave is more effective than using my steam cleaner.
The important thing to remember is not to use any detergents to clean the microwave, only use food or food safe products. You can use very weak washing up water, but certainly nothing stronger.
