Rubbermaid is a well-known brand that provides food storage containers that are inexpensive, lightweight, and extremely convenient. The question of whether these containers can be microwaved has sparked debate, with some believing they can and others believing it would ruin the container.
So, is it safe to microwave Rubbermaid? Yes, Rubbermaid containers manufactured after 2009 can be microwaved up to 212°F. They have a microwave-safe base and lid, so you can easily heat and defrost your food. We recommend that you always check the manufacturer’s label to see how long your Rubbermaid containers can be used safely.
Continue reading to learn whether it is safe to microwave Rubbermaid, if all Rubbermaid containers are microwave-safe, what you should and should not microwave in Rubbermaid, and much more.
Is It Safe To Microwave Rubbermaid?
Rubbermaid manufactures food storage containers that you can use in the microwave to reheat or defrost your meals. According to the manufacturer, the unique materials used to make Rubbermaid containers can withstand normal home use, including microwave use. Microwaves generate electromagnetic radiation to heat food, so it is critical that storage containers and cookware do not repel the radiation. Rubbermaid containers are microwave-safe and are designed to allow radiation to pass through and heat the food inside. They are also unlikely to become overheated.
The containers are also microwave-safe, and there is a safety logo to back this up. You should be able to find this label on the container or its packaging. It’s worth noting that the microwave symbol may differ depending on where the product was made — it could be a microwave with waves inside, a box with waves inside, or a #5 inside a triangle. These microwave-safe symbols can be used alongside other symbols, such as dishwashing symbols.
Aside from the microwave-safe symbol, another thing to look for is whether the containers contain BPA. To be sure, look for a BPA-free label on the container. BPA (Bisphenol-A) is a chemical compound used in the production of hard, clear plastic, such as that used in storage containers. If it contains BPA, it will melt when heated and leach into the food contained within the container. This is extremely dangerous because eating foods heated in BPA-containing containers allows plastic and chemicals into our bodies.
Can You Microwave Plastic Rubbermaid?
Plastic is a cheap, moldable, long-lasting, and recyclable material. ABS and HDPE, both of which are safe for food, are the two primary types of plastic used in Rubbermaid plastic products. Thankfully, all Rubbermaid products are marked as being BPA-free. To verify for yourself, simply look for the BPA-free sticker!
Today, Rubbermaid uses a unique blend of high-quality plastics that adhere to FDA regulations and are free of BPA and other dangerous substances. Additionally, the producers guarantee that the plastic won’t leak or introduce chemicals into your food. Given how dangerous these substances can be, it is best to treat plastic containers without a BPA-free label as non-microwaveable if you can.
Are All Rubbermaid Containers Microwave-Safe?
No, not all Rubbermaid containers are microwave-safe, especially those made before 2009 because they contain BPA. But don’t worry, Rubbermaid storage containers manufactured after 2009 are BPA-free and microwave-safe. If you have an old Rubbermaid container that you still use, do not microwave it. Plastic deteriorates over time, so check the manufacturer’s label to see how long you can safely use your Rubbermaid containers.
Rubbermaid now manufactures products from a variety of materials. The majority of them are made of plastic, crystal, and glass. Rubbermaid Brilliance glass containers are microwave-safe and made of high-temperature-resistant tempered glass. They can also be stacked, making them ideal for storage. They can also be baked at 450°F. Your meals can be heated or defrosted in the oven with or without the lid. When using the Mylar Foil lids that come with most Rubbermaid food storage sets, place them under the food for easy clean-up.
Are Rubbermaid Lids Microwave-Safe?
Rubbermaid lids can be microwaved safely, but only if they are slightly ajar. Ventilation and elimination of pressure from trapped moisture are both improved by cracking the lids just a crack. This may increase the likelihood of messy microwave spills involving food. If you want to avoid having to do this, leave the lid ajar or slightly lifted. You can forego the lid altogether, but doing so may cause your food to overheat; therefore, we recommend leaving it on, but cracked. Rubbermaid’s 3-, 5-, and 7-cup containers are great because they have vented lids that let steam out and shield food from getting splattery in the microwave.
Can You Microwave Rubbermaid At High Temperatures?
Rubbermaid cannot be microwaved at high temperatures. While they are microwave-safe, you must be careful not to overheat them because there is a temperature limit that they can withstand. Rubbermaid products can withstand temperatures as high as 212°F (100°C), which is the boiling point of water. Any higher will damage the container and may even cause the plastic to deform and melt.
Because of the risk of leaching at higher temperatures, Rubbermaid should only be used for reheating and never for cooking. Before putting the product in the microwave, it is recommended that you read the manufacturer’s instructions and guidelines about the product’s limitations and how to best use it.
What Should You Never Microwave In Rubbermaid?
Rubbermaid’s manufacturers expressly advise against microwaving a number of foods because they will start to cook too quickly and pose a fire risk. These include syrups and sauces with sugar as well as fatty and oily foods. They can be microwaved for brief intervals while being closely watched, but it’s risky and we don’t advise it. Reheating these foods is not advised even for Rubbermaid products that are marked as microwave-safe because they might heat up excessively and harm the container.
Watery foods like soup, items like leftover meatloaf and vegetables, and other items won’t heat above the safe temperature when heated in the microwave in Rubbermaid containers, so there’s no need to be concerned. When heating tomatoes (or anything else containing tomatoes), exercise caution because doing so will ruin the plastic’s appearance and functionality.
Tips For Microwaving Rubbermaid
Here are a few tips and tricks to keep in mind when using and microwaving your Rubbermaid containers:
Before putting your Rubbermaid container in the microwave, remove all labels and packaging materials.
To avoid damaging your Rubbermaid container, read the manufacturer’s instructions and safety guidelines on what to do and what not to do.
Only reheat and defrost in this container. It cannot withstand high temperatures and will warp, melt, and leach if used directly in cooking or steaming.
Microwave on low to medium power, as high temperatures may damage the Rubbermaid container.
To avoid high temperatures, heat your food in short bursts of 1 minute or less.
Do not allow your food to become too hot. Use a glass or ceramic container for higher temperatures.
Avoid overfilling the container, as this increases the likelihood of spilling. It could also cause uneven heating and make you want to leave the container in there for longer.
When microwaving, do not tightly close the lid of your Rubbermaid container. If it has a vent, make sure it’s open to let the steam out.
Because the plastic may become hot, remove the container from the microwave using a kitchen towel or heat-resistant gloves.
When removing the lid, be cautious of steam because the reheated food can become very hot.
Never microwave empty Rubbermaid plastic containers because the heat will become concentrated, deforming and rendering the container unusable.
Here are some additional inquiries we thought you might have now that you are fully informed about Rubbermaid containers and whether or not you can use them in the microwave.
Are Rubbermaid containers freezer-safe?
Yes, Rubbermaid containers can be frozen. They are made of strong materials that can withstand the freezing temperatures. You can use them to keep your food frozen; however, vacuum-sealing is the preferred method for long-term storage.
Are Rubbermaid containers dishwasher-safe?
Your Rubbermaid containers can be cleaned in the dishwasher. Use gentle cleaners when washing by hand. Use a non-scratch nylon scouring pad to soak and clean the containers for tougher stains. Additionally, the lids are top-rack dishwasher safe.
Can you microwave Tupperware?
Since March 2010, Tupperware sold in the United States and Canada has been BPA-free and thus microwave-safe. The containers are marked with a microwave-safe symbol, which is a box with waves inside it. They are also dishwasher and freezer safe in most cases.
