I’ve always loved using microwaves. They’re quick and convenient, making our lives a whole lot easier. Whether it’s reheating last night’s leftovers or heating up a frozen meal, microwaves are a staple in every kitchen. However, it’s important to know that not all materials are suitable for the microwave. Using the wrong materials can lead to disaster, from damaging your microwave to even starting a fire. So, let’s dive into what materials you should never put in a microwave for safe usage.
Plastics – Not All Created Equal
Types of Plastics to Avoid
Plastics are a common material found in our homes. However, not all plastics are created equal when it comes to microwave usage. The key is to look for the microwave-safe symbol, which typically consists of wavy lines or a small microwave icon. Avoid putting the following types of plastics in the microwave:
- PETE or PET (polyethylene terephthalate)
- PS (polystyrene)
- PC (polycarbonate)
These plastics can release harmful chemicals when exposed to high temperatures, which can end up in your food and be harmful to your health.
Plastic Containers and Saran Wrap
Even if a plastic container is labeled as microwave-safe, it’s essential to use caution. Here are a few tips to follow:
- Avoid using old, cracked, or discolored containers as they could leach harmful substances into your food.
- Avoid tightly covering food with plastic wrap as it can create a steam effect, causing the wrap to melt and potentially contaminate your food.
- Always open the container away from your face to prevent any potential steam burns.
Metallic Objects – A Recipe for Disaster
Aluminum Foil and Metal Utensils
We’ve all been tempted to cover our food with aluminum foil while microwaving it for a faster cooking time. However, this is a huge mistake. The foil can cause sparks, leading to a fire, and even damage your microwave.
The same goes for metal utensils. The microwaves bounce off metal, which can cause a dangerous buildup of energy. This can create a hazardous situation, so it’s best to stick to microwave-safe utensils.
Metal Trim and Decorations
While most microwave interiors are made of metal, it’s the metal trim or decorations you need to be cautious of. Avoid microwaving dishes with metallic borders, including those with gold or silver accents. The metal can cause sparks and damage your microwave.
Foam Containers – A Melting Mess
Styrofoam and Other Foam Plastics
Foam containers, such as those used for take-out meals or food packaging, should never be microwaved. When exposed to high temperatures, these containers can melt, releasing harmful chemicals into your food. Always transfer the food into a microwave-safe container before reheating.
Cups and Plates
Some cups and plates are also made of foam materials and should not be microwaved. Always check the packaging or the bottom of the cup/plate for the microwave-safe symbol or any instructions regarding microwave usage.
Other Materials to Beware Of
Besides plastics, metallic objects, and foam containers, there are a few other materials you should avoid putting in the microwave:
Paper Bags
Microwaving paper bags can cause them to catch fire. Stick to microwave-safe paper products or transfer food onto a microwave-safe plate.
Wax Paper
Wax paper can melt or even ignite when exposed to high temperatures. It’s best to stick to parchment paper or microwave-safe covers when covering your food.
Anything with a Metallic Trim
Similar to metal decorations, anything with a metallic trim can cause sparks. Be cautious when using microwave-safe dishes with metallic accents.
Conclusion
Microwaves are incredibly convenient, but it’s crucial to use them safely. Understanding what materials you should never put in a microwave can prevent accidents, damages, and potential health risks. Remember to always check for the microwave-safe symbol on plastics and use caution when dealing with metals, foam, and other potentially hazardous materials. By following these guidelines, you can enjoy the convenience of your microwave without any worries.
