Fire safety guidance recommends keeping towels and other flammable materials away from active cooking surfaces because they can ignite.
What Should Never Go in a Dishwasher
Some household items are better washed by hand, including:
Delicate glassware.
Sharp knives.
Wooden cutting boards and utensils.
Cast-iron cookware.
Some plastic containers.
Non-stick pans, depending on the manufacturer’s instructions.
These items can become damaged or damage the dishwasher over time.
Simple Kitchen Habits That Improve Safety
Keep a dry towel nearby—not on a hot appliance.
Clean up broken glass carefully.
Follow the care instructions for cookware.
Keep flammable materials away from heat sources.
Replace cracked glassware before it breaks.
Final Thoughts
Small kitchen habits can make a big difference. A towel is a useful tool when used correctly, but it should always be kept away from active heat. Knowing which items belong in the dishwasher—and which don’t—can also help prevent damage and keep your kitchen safer.
