How To Kasher A Microwave

How To Kasher A Microwave

There are two different kinds of microwave ovens. Some of them have a heating element and can be used like a regular oven. Others work by using radiation to warm up the food as opposed to using actual heat. The ones that have a heating element can kashered for Pesah the same way as a regular oven: by waiting 24 hours from the last use, cleaning it well, and turning it on the highest setting for an hour or so. The microwaves that work through radiation need to kashered even though generally they are used to warm things up rather than to cook. These are kashered by cleaning them well and boiling a cup of water with some soap (not poisonous) until the walls of the microwave have steam on them. If they are in a public place and are being constantly used they should not be kashered. Serving trays that are not used to cook on may be kashered by pouring boiling hot water on them directly from the pot the water was cooked in.
