How to Kasher a Microwave

How to Kasher a Microwave
Day: Wednesday
Date: April 6, 2016
Parshat: Tazriah, HaChodesh
Yalkut Yosef: O"H: 451


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 by way of radiation need to kashered even though generally they are used to warm things rather than to cook things. These microwaves can be kashered by cleaning them well and boiling a cup of water with (non toxic) soap until the walls of the microwave have steam on them. As an extra precaution, it is also good to wrap well everything that is heated in the microwave during Pesah. Microwaves in more public places that are constantly used or even private microwaves that are used so much that the walls generally become very hot should not be kashered for Pesah. Serving trays that are not used to cook on may be kashered by pouring boiling hot water on them directly from a kli rishon.
