Understanding Microwave Covers

Microwave covers are typically made from plastic, silicone, or glass. They serve multiple purposes, including keeping food moist, preventing splatters, and promoting even heating. While these covers are convenient, it’s crucial to know whether they can be safely cleaned in a dishwasher.

Types of Microwave Covers

  1. Plastic Covers
    • Lightweight and affordable
    • Vary in heat resistance
  2. Silicone Covers
    • Flexible and durable
    • High heat resistance
  3. Glass Covers
    • Heavy and sturdy
    • Excellent heat resistance

Dishwasher Safety: What You Need to Know

Not all microwave covers are created equal, and their dishwasher safety depends on the material and construction. Here’s a detailed breakdown of each type:

Plastic Microwave Covers

Plastic covers are the most common due to their affordability and lightweight nature. However, not all plastics are created equal.

  • Heat Resistance: Check the label for heat resistance. Some plastics can warp or melt at high temperatures.
  • BPA-Free: Ensure the plastic is BPA-free to avoid harmful chemicals leaching into your food.
  • Dishwasher Safe Label: Always look for a dishwasher-safe label. If it’s not mentioned, hand washing is recommended.

Silicone Microwave Covers

Silicone covers are known for their flexibility and durability. They can withstand high temperatures without warping.

  • Heat Tolerance: Silicone covers generally have a high heat tolerance, making them safe for the top rack of the dishwasher.
  • Non-Toxic: Silicone is a non-toxic material, safe for food use.
  • Easy Cleaning: These covers are easy to clean, and their non-stick surface makes them ideal for dishwasher use.

Glass Microwave Covers

Glass covers are the most durable and can withstand high temperatures without any issues.

  • Heat Resistance: Glass covers are highly heat-resistant and can handle the heat of a dishwasher cycle.
  • Weight: Their weight makes them stable in the dishwasher.
  • Cleaning: Glass is non-porous and easy to clean, making it an excellent choice for dishwasher use.

Best Practices for Cleaning Microwave Covers

To ensure the longevity and safety of your microwave covers, follow these best practices:

Read the Manufacturer’s Instructions

Always start by reading the manufacturer’s instructions. They provide crucial information on the material and its dishwasher safety.

Top Rack Placement

If the cover is dishwasher safe, place it on the top rack. The top rack experiences less intense heat and reduces the risk of warping or damage.

Avoid High-Heat Cycles

Use a gentle or eco-friendly cycle if possible. High-heat cycles can be too harsh for some materials, especially plastics.

Regular Inspection

Regularly inspect your covers for any signs of damage or wear. Cracks, warping, or discoloration are signs that the cover may no longer be safe to use in the microwave or dishwasher.

Common Misconceptions About Dishwasher Safety

There are several misconceptions about the dishwasher safety of microwave covers. Let’s address some of the most common ones:

All Microwave Covers Are Dishwasher Safe

This is not true. Always check the label or manufacturer’s instructions to ensure your cover is dishwasher safe.

Plastic Covers Are Always Unsafe

While some plastics may not be dishwasher safe, many modern plastic covers are designed to withstand dishwasher cycles. Check for heat resistance and BPA-free labels.

Silicone Covers Are Indestructible

Although silicone covers are highly durable, they are not indestructible. Avoid exposing them to sharp objects or excessive heat cycles that could degrade the material over time.

Glass Covers Don’t Need Special Care

While glass is durable, it can still break if not handled properly. Always place glass covers securely in the dishwasher and avoid overcrowding to prevent damage.


In conclusion, whether a microwave cover is dishwasher safe depends largely on the material it’s made from. Plastic, silicone, and glass covers each have their own characteristics and cleaning requirements.

By following the manufacturer’s instructions and best practices, you can ensure that your microwave covers remain in excellent condition and safe for use.

Remember, regular inspection and proper placement in the dishwasher are key to maintaining the longevity of your microwave covers. By doing so, you’ll continue to enjoy the convenience and benefits they offer in your kitchen.
