Rubbermaid is a popular brand known for its high-quality food storage containers and kitchen products. Many people wonder if these containers are safe to use in the microwave.
In this article, we’ll answer that question and delve into the factors that determine microwave safety, proper use, and care of Rubbermaid products.
Yes, most Rubbermaid containers are microwave safe, but it’s essential to check for the microwave-safe symbol on the product before use.
Now, let’s dive deeper into the topic of microwave safety and Rubbermaid products, exploring the different types of containers, how to use them properly, and tips for maintaining their quality.
Understanding Microwave Safety
Microwave safety is crucial when it comes to heating food in microwave ovens. Using the wrong type of container can lead to harmful chemical leaching, melting, or even damage to your microwave.
Microwave-safe materials include glass, ceramic, and certain types of plastics that can withstand high temperatures without releasing harmful chemicals.

Rubbermaid Products and Microwave Safety
Rubbermaid offers a wide range of food storage containers, and many of them are designed to be microwave safe. These containers are made from high-quality plastic materials like BPA-free polypropylene and polycarbonate, which can withstand high temperatures without warping or releasing harmful substances.
To determine if a Rubbermaid container is microwave safe, look for the microwave-safe symbol on the bottom of the container or the packaging.
This symbol typically looks like a series of wavy lines or a microwave with wavy lines inside. If you’re unsure, it’s best to check the product information on the Rubbermaid website or contact their customer service for clarification.
Using Rubbermaid Containers in the Microwave
When using Rubbermaid containers in the microwave, follow these guidelines to ensure safe and efficient heating:
- Choose the right size: Select a container that is large enough to hold your food without overflowing. Leave some space between the food and the container’s sides to allow for proper heat circulation.
- Vent the lid: When microwaving food in a Rubbermaid container, make sure to loosen the lid or use a vented lid to allow steam to escape. This prevents pressure build-up, which can cause the container to warp or the food to spill.
- Stir or rotate food: For even heating, stir or rotate the food halfway through the cooking process. This helps redistribute the heat and prevents cold spots.
- Use microwave-safe accessories: If you need to cover your food while microwaving, use a microwave-safe cover or microwave-safe plastic wrap. Avoid using metal or aluminum foil, as these materials can cause sparks and damage your microwave.
- Monitor cooking times: Since microwaves vary in wattage and power, cooking times may differ. Keep an eye on your food to prevent overcooking or burning.
Caring for Your Rubbermaid Containers
To maintain the quality and longevity of your Rubbermaid containers, follow these care tips:
- Cleaning: Most Rubbermaid containers are dishwasher safe, but it’s best to place them on the top rack to prevent warping from high temperatures. You can also hand-wash them with warm, soapy water.
- Avoid abrasive cleaners: To prevent scratches, avoid using abrasive cleaners or scouring pads on your Rubbermaid containers. Instead, use a soft sponge or cloth.
- Store with care: To prevent warping, allow your containers to cool completely before stacking and storing them. Additionally, store the lids separately or loosely placed on top of the containers to prevent pressure build-up.
- Inspect for damage: Regularly inspect your Rubbermaid containers for signs of wear or damage, such as cracks or warping. If you notice any issues, it’s best to replace the container to ensure safe and efficient use.
