Is it safe to use a burnt microwave

If you overcook something for too long, sometimes sparks fly, food is burnt, or even flames fly inside the microwave, such things generally leave behind an unpleasant residue such as soot and scorch.

Afterward, it is normal to wonder whether it is still safe to use a burnt microwave?

A burned microwave should not be used, as it can cause the appliance to heat up rapidly or cause a fire. Though in some cases if the burn is not too serious, you can clean the microwave interior with lemon juice and warm water, a little brushing to get rid of any soot and scorch marks, and then use it as usual. But still I would say don’t use the burned microwave if you are unsure about any internal damage.
