Can Microwave Plate Go In Dishwasher

In today’s fast-paced world, convenience is key, and one of the most convenient kitchen appliances we rely on daily is the microwave. It’s a time-saving wonder that reheats leftovers, defrosts frozen foods, and even cooks entire meals with just a push of a button. However, when it comes to cleaning up, many questions arise, one of them being: Can a microwave plate go in the dishwasher? In this article, we will explore this common kitchen dilemma and provide you with valuable insights to keep your kitchenware in tip-top shape.

The Microwave Plate: Material Matters

Understanding the Composition

Microwave plates are typically made of three main materials: glass, ceramic, or plastic. The material of your microwave plate plays a crucial role in determining whether it can safely go into the dishwasher.

Glass Microwave Plates

Glass microwave plates are the most common type, known for their durability and heat resistance. The good news is that glass microwave plates can generally go into the dishwasher without any issues. However, it’s essential to check for any manufacturer-specific instructions or warnings.

Ceramic Microwave Plates

Ceramic microwave plates are also dishwasher-safe in most cases. These plates are robust and can withstand the dishwasher’s heat and water pressure. Still, always double-check the manufacturer’s recommendations.

Plastic Microwave Plates

Plastic microwave plates are a bit trickier. While some plastic plates are labeled as dishwasher-safe, many are not. Heat and the aggressive water pressure in dishwashers can cause warping, cracking, or even releasing harmful chemicals from certain plastics. Therefore, it’s best to handwash plastic microwave plates to prevent damage and ensure food safety.

The Dishwasher: A Word of Caution

Dishwasher Temperature and Agitation

Dishwashers are designed to clean dishes thoroughly, but they can be harsh on some materials. The high water temperature and the mechanical agitation used in dishwashers may affect microwave plates differently based on their composition.

Glass and Ceramic Plates

As mentioned earlier, glass and ceramic plates can typically handle the dishwasher’s conditions. However, over time, frequent dishwasher use may lead to wear and tear. To extend the lifespan of your microwave plates, consider handwashing occasionally.

Plastic Plates

For plastic microwave plates, the dishwasher can be particularly damaging. The combination of heat and water pressure can cause warping or even melt the plastic. To maintain the integrity of your plastic plates, it’s best to handwash them using mild detergent and lukewarm water.

Proper Care and Maintenance

Tips for Microwave Plate Longevity

To ensure your microwave plates remain in excellent condition, follow these simple tips:

  1. Inspect Labels: Always check for manufacturer labels or instructions regarding dishwasher safety.
  2. Avoid Abrasive Cleaners: Use gentle dishwashing detergent and a soft sponge or cloth to clean your microwave plates.
  3. Regular Inspection: Periodically inspect your plates for any signs of damage or wear.
  4. Handwashing: Consider handwashing your plates occasionally to extend their lifespan.


In conclusion, the question of whether a microwave plate can go in the dishwasher depends on its material. Glass and ceramic plates are generally safe for dishwasher use, while plastic plates are best handwashed to prevent damage. Remember to check manufacturer instructions and practice proper care to ensure your microwave plates stay in excellent condition for years to come.
