Microwave Safety: 10 Things to Never Heat Up
Microwaves are incredibly useful, but using them incorrectly can lead to safety hazards, damage to the appliance, or ruined food. Here’s a guide to items and materials you should never microwave:
1. Metal Objects
- Reason: Metals deflect microwave energy, creating sparks that may cause a fire or damage the microwave.
- Examples: Aluminum foil, cutlery, or metal-lined containers.
2. Styrofoam
- Reason: Many Styrofoam products contain chemicals that can melt or release toxins when heated.
- Better Option: Transfer food to a microwave-safe dish before heating.
3. Non-Microwave-Safe Plastics
- Reason: Some plastics can release harmful chemicals like BPA or break down when exposed to high temperatures.
- Tip: Always check for a microwave-safe label before heating.
4. Liquids Without a Cover
- Reason: Heating uncovered liquids can lead to superheating, where they suddenly boil over or erupt when disturbed.
- Solution: Use a cover or microwave-safe lid and heat in short intervals.
5. Eggs in Their Shell
- Reason: Heat causes pressure to build inside the shell, often resulting in an explosion.
- Alternative: Crack the egg and cook it scrambled or poached instead.
6. Paper Bags
- Reason: Standard paper bags can ignite or release toxic fumes when heated.
- Exception: Only use special microwave popcorn bags designed for this purpose.
7. Certain Fruits
- Reason: Grapes, for example, can spark and create a fire risk, while other fruits may explode as steam builds up inside them.
- Tip: Heat fruits with caution, and always slice them first.
8. Uncovered Food
- Reason: Foods heated without covers tend to splatter, leaving behind a mess and potential bacterial contamination.
- Fix: Cover with a microwave-safe lid to keep the microwave clean.
9. Wet Clothes or Fabrics
- Reason: Attempting to dry clothes in a microwave can lead to burning or even fires.
- Safer Choice: Use a dryer or hang clothes to air-dry.
10. Dishes Without a Microwave-Safe Label
- Reason: Certain ceramics and glassware can crack, overheat, or leach harmful substances into food.
- How to Check: Look for a label indicating the dish is safe for microwave use.
To avoid accidents, always follow safety guidelines and check labels before placing items in the microwave. When unsure, opt for alternative methods like using a stovetop or conventional oven.
