Some items can release toxins, catch fire, melt, or even explode if heated for less than a minute. Some can even be harmful to your health.
So protect yourself and others by keeping these things away from the microwave.
Styrofoam
Food-grade Styrofoam is a type of plastic that can release harmful chemicals into food and air when heated. Styrofoam is also not heat stable when placed in the microwave. It can melt or warp.
It’s best to place food on a plate or glass container instead of heating it in styrofoam. Then simply cover the food with a paper towel and microwave as usual.
Metal Handled Food Tray
Food trays with metal handles can cause sparks and catch fire. As a general rule, check if any plastic food tray or container is labeled “Microwave Safe” before using it.
Instead of placing the tray in the microwave, you should transfer the leftover food to a microwave-safe container or plate. Cover it with a paper towel to prevent splatters and heat as usual.
Water cup
Heating water for tea in the microwave may be much quicker than using a regular kettle, but saving time can come at a cost.
Water heated in the microwave can quickly become superheated. Although you don’t see any bubbles, they can quickly form when you add a tea bag, spoon, or even just stir the water. In rare cases, it can even explode.
Tin Foil
When wrapping food in tin foil and placing it in the microwave, the microwave waves do not penetrate, creating arcing electrical sparks that can cause the oven to catch fire. Also, you should never put a paper bag, plastic bag, or newspaper in the microwave as they can release harmful gases or catch fire at high temperatures in the oven.
Paper Bag, Plastic Bag
You should never put a paper bag, plastic bag, or newspaper in the microwave as they can release harmful gases or catch fire at high temperatures in the oven.
Absolutely do not wrap food in tin foil and then put it in the microwave, as tin foil also contains metal and can ignite.
