The microwave has been a staple in modern kitchens for decades, offering convenience for reheating and cooking. However, despite its versatility, some may not know that, not everything belongs inside them. Misuse can lead to messes, ruined food, or more seriously can damage to the appliance. Here’s a guide on what not to cook or place in your microwave to keep it safe and effective.
Non-Food Items That Spell Trouble for Microwaves
1. Plastic
Plastic containers, wraps, and utensils can warp or melt under microwave heat. This not only creates an awful mess but also releases harmful toxic chemicals that may leach into your food. Unless labelled “microwave-safe,” plastic should be avoided entirely.
2. Metal
Microwaving metal objects, such as utensils, foil, or travel mugs. Doing so could result in arcing, causing unrepairable damage internally to the microwave.
3. Paper Towels (Improperly Used)
While paper towels can be useful for covering food, using them incorrectly can lead to overheating or combustion. Overheating dry paper towels can result in fire hazards, especially if they touch the microwave walls or food.
4. Non-Microwave-Safe Ceramics and Glassware
Not all ceramics and glassware are created equal. Some can crack or shatter due to uneven heating. Unless of course ‘microwave safe’ is stated.
Foods That Don’t Fare Well in Microwaves
1. Eggs in Their Shells
Microwaving eggs is perfectly possible but must be done correctly. Cooking eggs in their shell (for “boiled” eggs) leads to pressure build-up inside the egg, causing them to explode.
2. Whole Fruits
Fruits like grapes and whole apples with high water content can overheat and burst due to steam build-up inside and the harder skin building pressure.
3. Hot Peppers
Another less know product to avoid putting in your microwave are hot peppers. Peppers releases capsaicin into the air, which can irritate your eyes and throat. The heat can also cause peppers to burst, leaving spicy residues inside the microwave.
4. Sauces or Liquids Without Covers
Uncovered liquids and sauces tend to splatter during heating, leaving a sticky mess on the interior walls of your microwave. This can harden and become challenging to clean. Look out for microwave safe bowls and lids for safely heating through meals and avoid the need for extra cleaning.
5. Potatoes (Unpierced)
Microwaving whole potatoes without piercing their skin can lead to an excessive build-up of steam. Again, like with other produce named on the list, microwaving high water content foods with thicker skins can cause pressure and potential explosions within the microwave.
Always pierce potatoes with a fork before cooking to allow steam to escape.
Overloading: Uneven Heating and Poor Results
Using an incorrect sized plate or overloading or your microwave with too many items at once can block the rotation and airflow needed for even heating. Due to the way most conventional microwaves work, rotation is crucial to oven cooking and correct operation. If a rotating plate is unable to rotate it will result in food that’s hot in some spots and cold in others.
Cleaning and Maintenance
Keeping your microwave clean and well-maintained is key to ensuring its longevity.
- Wipe down the interior after each use to prevent build-up from splatters. For tougher stains, heat a bowl of water with lemon slices for a few minutes to loosen grime, then wipe clean.
- Regularly check the turntable for debris and ensure it rotates smoothly.
- Avoid using abrasive materials that could scratch the surface.

Proper care will not only extend the life of your microwave but also ensure your food is cooked safely and evenly.
Conclusion: Protect Your Microwave, Cook with Care
The microwave is an invaluable tool, but it requires more thoughtful use than close the door and switch it on. Avoid putting in items like plastic or metal into a microwave to avoid damage to internal parts. Steer clear of foods prone to explosions or messes, like eggs, uncovered liquids, and unpierced potatoes.
With proper care and mindful choices, your microwave will remain a reliable kitchen companion for years to come.
