Can I Microwave Rubbermaid Tupperware: Safety Guidelines

Can I Microwave Rubbermaid Tupperware

Microwaving Rubbermaid containers are generally considered safe, as long as the containers are specifically labeled as “microwave safe“. Rubbermaid makes a variety of plastic food storage containers, but not all of them are intended for use in the microwave.

What Makes a Container Microwave Safe?

For a container to be microwave-safe, it must be made from plastic that can withstand the high temperatures inside a microwave oven without leaching chemicals into the food. Many plastics contain chemicals like bisphenol A (BPA) that can leach out when heated.

Microwave-safe plastics are:

• Made without BPA or other harmful chemicals
• Able to withstand temperatures up to 212°F (100°C), the boiling point of water
• Free of dyes or decorations that could melt or leach into food

Are All Rubbermaid Containers Microwave Safe?

Not necessarily. Some, but not all, Rubbermaid food storage containers are labeled as microwave-safe. Containers that are not microwave-safe may melt or warp when microwaved, and chemicals could leach into food.

Here are some tips on identifying microwave-safe Rubbermaid containers:

• Check for the microwave safe symbol – This looks like a microwave with wavy lines. Containers with this symbol are safe for microwave use.
• Look at the lid and base – Both the lid and base need to be microwave-safe. Many container lids are not meant for microwaving.
• Don’t rely on old containers – The plastics used in older Rubbermaid containers may not meet current standards. Check the bottom for a microwave-safe symbol.
• Don’t microwave containers with metallic paint or decorations – Metallic materials can damage the microwave or spark.

Some Rubbermaid product lines that are microwave-safe include:

• Brilliance containers
• Easy Find Lids containers
• TakeAlongs microwaveable containers
• Microwave Microburst containers

If in doubt, check the manufacturer’s instructions or Rubbermaid’s website for specifics on your container.

Microwaving Rubbermaid Containers Safely

When microwaving any plastic container, follow these tips:

• Don’t microwave it empty – Always keep food or water inside. This absorbs more energy and prevents warping.
• Remove the lid – Most container lids are not microwave-safe. Leave it slightly ajar to vent steam.
• Don’t microwave for a long time – Heat food in short bursts, checking frequently.
• Allow standing time – Let food rest for 2-3 minutes before removing. This equalizes temperature.
• Don’t use old or damaged containers – Signs of wear like stains, cracks, or clouding indicate it’s time to replace it.
• Don’t microwave anything with metal – Never microwave containers with metallic paints, metal lids, or aluminum foil.

Following the manufacturer’s instructions is always recommended when using any container in the microwave.

FAQs

Can you microwave Rubbermaid lids?

Most Rubbermaid lids are not designed to be microwaved. Always remove lids before putting Rubbermaid containers in the microwave unless the container and lid are both labeled microwave-safe.

Is it safe to microwave old Rubbermaid containers?

Older Rubbermaid containers may not meet current safety standards for microwave use. Check containers for any signs of damage and look for the microwave-safe symbol before using them. When in doubt, it’s best to play it safe and avoid microwaving old containers.

Do Rubbermaid containers contain BPA or other chemicals?

Current Rubbermaid containers are BPA-free. However, older containers may have contained BPA or other chemicals that could leach when microwaved. Always check and only use newer Rubbermaid containers labeled as microwave-safe.

Can you microwave Rubbermaid plastic?

You can safely microwave plastic Rubbermaid containers as long as they are labeled for microwave use. Containers made from polyethylene terephthalate (PETE type 1) or polypropylene (PP type 5) plastics are microwave-safe. Avoid containers made with plastic types 3, 6, and 7.

Is boiling water in Rubbermaid safe?

Yes, microwave-safe Rubbermaid containers are designed to withstand boiling water. Always check the label to confirm the container is microwave and boil-proof. Never microwave empty containers as this can damage the plastic.

Can Rubbermaid go in the dishwasher?

Most Rubbermaid containers are top-rack dishwasher safe. However, the high heat can eventually cause wear. Hand-washing containers are recommended to prolong their lifespan. Avoid putting Rubbermaid lids in the dishwasher.

Are There Any Risks to Microwaving Plastic Containers?

Microwaving any plastic does come with minor risks, even those labeled microwave-safe. The FDA considers current microwave-safe plastic containers to be safe when used as directed. However, it’s smart to take precautions:

• Don’t microwave older or scratched plastic, which is more likely to leach chemicals.
• Avoid microwaving fatty or acidic foods, which can cause more leaching.
• Don’t microwave plastic on high power for more than 3-4 minutes at a time.
• Never microwave Styrofoam, plastic bags, or plastic wraps not rated for microwave use.

While occasional use of microwave-safe plastic is considered safe, choose glass or ceramic containers whenever possible. Never microwave plastic containers that are cracked, stained, or show signs of wear. And be sure to follow all manufacturer’s instructions.

Conclusion

Most modern Rubbermaid food containers are safe to use in the microwave if clearly labeled for microwave use. But microwaving any plastic does come with some risks. Following microwave safety best practices, checking for the microwave safe symbol, and closely following the manufacturer’s instructions can help minimize risks.

When uncertain if a container is microwave-safe, don’t chance it. Instead, transfer food to microwave-safe glass or ceramic dish before heating. With proper care and caution, Rubbermaid containers are convenient, durable options for microwave cooking and reheating leftovers.
