Keeping a kosher kitchen involves ensuring that all appliances are properly maintained according to Jewish dietary laws. If a microwave has been used for non-kosher food or for both meat and dairy, it must be kashered before it can be used again. This process is especially important when preparing for Pesach. Here’s a step-by-step guide to kashering a microwave:
Step 1: Clean the Microwave Thoroughly
Before beginning the kashering process, clean every part of the microwave thoroughly. Remove any food residue from the walls, turntable, and door. Use a non-abrasive cleaner and ensure that no crumbs or grease remain.
Step 2: Let It Sit for 24 Hours
If possible, refrain from using the microwave for 24 hours to allow any absorbed taste to dissipate. This is not always required, but it is recommended by many authorities.
Step 3: Boil Water to Create Steam
Place a cup or bowl of water with a few drops of dish soap inside the microwave. Run the microwave on the highest setting until the water boils and produces steam. The steam helps to remove absorbed tastes from the walls and ceiling of the microwave.
Step 4: Wipe Down the Interior
Once the steaming process is complete, carefully remove the cup or bowl (it will be hot) and wipe down the inside of the microwave with a clean, damp cloth.
Step 5: Kosher the Turntable
If the microwave has a glass turntable, it is preferable to replace it with a new one. If this is not possible, clean it thoroughly and cover it with a microwave-safe barrier (such as a thick paper towel or microwave-safe plate) when using the microwave.
Step 6: Maintaining a Kosher Microwave
By following these steps, you can properly kasher a microwave and ensure it remains in accordance with kosher dietary laws. This is particularly important when preparing for Pesach. For specific guidance, consult a local rabbi or halachic authority.
