Did You Know?

1. Contrary to popular belief, not all Tupperware containers are dishwasher safe. While many Tupperware products are designed to withstand the high heat and water pressure of a dishwasher, some containers may warp or crack under these conditions. It is important to check the specific instructions provided by the manufacturer before placing Tupperware in the dishwasher.

2. One of the reasons some Tupperware containers cannot go in the dishwasher is due to the composition of the plastic used. Tupperware often contains a type of plastic called polypropylene, which is generally dishwasher safe. However, certain additives and colorants used in the manufacturing process can make the plastic more susceptible to damage and discoloration in the dishwasher.

3. While most Tupperware lids can be safely washed in the dishwasher, it is recommended to place them on the top rack. This is because the top rack generally experiences lower heat levels and less intense water pressure, reducing the risk of warping or damage to the lid.

4. To prolong the lifespan of your Tupperware, even when it is labeled as dishwasher safe, it is advisable to opt for the gentle or delicate cycle on your dishwasher. This can help prevent excessive wear or damage to the containers over time.

5. Despite the dishwasher being a convenient option for cleaning Tupperware, handwashing with mild soap and warm water is always a safe and effective way to ensure the longevity of your containers. This method also allows for better control and inspection of the containers, ensuring they are thoroughly clean and free from any trapped food particles.

Hand-Wash Or Use Top Rack For Tupperware Without Dishwasher-Safe Symbol

Hand-washing Tupperware ensures that it receives gentle treatment and minimizes the risk of any damage during the cleaning process. If you choose to use the dishwasher, placing your Tupperware on the top rack will help prevent it from dislodging or coming into direct contact with the heating element, which could potentially warp or melt the plastic.

It is also important to note that plastics in the dishwasher may not dry completely. To avoid any potential water spots or moisture issues, it is best to hand dry your Tupperware thoroughly before storing it away. This will help maintain its quality and functionality over time.

Potential Health Risks Of Bpa In Tupperware And Plastic Containers

When using plastic containers like Tupperware, it is essential to be aware of potential health risks associated with certain chemicals, such as Bisphenol A (BPA). BPA is a chemical compound that has raised concerns due to its potential harmful effects on human health, particularly in the development of the nervous system.

Studies have suggested that BPA exposure may be linked to reproductive disorders and even breast cancer. However, it is important to note that Tupperware claims to have discontinued the use of BPA in their products since March 2010. This means that Tupperware containers made after this date should be free of BPA. However, it is still possible that older Tupperware containers, manufactured before the company’s transition away from BPA, may contain the chemical.

Characteristics such as transparency, labels indicating microwave-safety or unbreakability, Resin Identification Code number 7, and the absence of any code can help identify if Tupperware contains BPA. Containers labeled as “hand-wash only” may be more likely to be BPA-free. It is important to note that containers that contain BPA are not safe for storing or microwaving food, as heating plastic increases the risk of harmful materials leaching into the food. If you are concerned about potential BPA exposure, using glass containers as an alternative to plastic is suggested.

Old Tupperware containers suspected of containing BPA can still be repurposed for non-food-related uses, such as organizing small items or holding craft supplies. However, it is recommended to avoid using them for storing or heating food to minimize any potential risks.

Tupperware Made Before 1979 Is Not Dishwasher Safe

If you happen to come across Tupperware made before 1979, it is important to note that these older containers are not dishwasher safe. The manufacturing processes and materials used during that time may not have been able to withstand the harsh environment of dishwashers. In order to preserve the quality and functionality of these vintage Tupperware pieces, it is best to hand wash them with care.

Tupperware purchased after 1979 is generally dishwasher safe, with the presence of a dishwasher-safe symbol on the product indicating so. For Tupperware without the symbol, it is recommended to wash it by hand or on the top rack of the dishwasher. Other brands like Rubbermaid, Snapware, and Lock&Lock also provide dishwasher-safe options. However, it is important to be mindful of potential health risks associated with BPA in plastic containers, including Tupperware. Always check the packaging and look for characteristics that indicate the absence of BPA. Lastly, vintage Tupperware made before 1979 should be hand washed to ensure its longevity. By following proper care and maintenance practices, you can ensure that your Tupperware remains durable and continues to serve you well in the kitchen.

Frequently Asked Questions

How do I know if my Tupperware is dishwasher safe?

To determine whether your Tupperware is dishwasher safe, examine the product for any indication or labeling of dishwasher safety. Tupperware made after 1979 is typically designed to withstand dishwasher use, so you can look for the “dishwasher safe” label or the presence of a specific symbol: a box with plates or glasses inside, accompanied by expressive lines or dots representing water. These markings serve as a helpful guide in determining the dishwasher compatibility of your Tupperware.

Can you put Tupperware in bottom dishwasher?

It is not recommended to put Tupperware in the bottom dishwasher. Placing Tupperware on the top rack is advised to avoid any contact with the heating element. The high temperature of the heating element can cause the plastic to warp or melt, potentially damaging both the container and the dishwasher. Therefore, to ensure the longevity of your Tupperware and the proper functioning of your dishwasher, it is best to adhere to the recommended placement.

Can Tupperware go in the dishwasher and microwave?

Yes, Tupperware sold in the United States and Canada since March of 2010 is safe for the dishwasher and microwave. These containers are BPA free and can be easily identified as microwave-safe by the microwave-safe emblem featured on the bottom, which is a box with squiggly lines. Additionally, Tupperware is generally designed to be freezer safe, providing convenient storage options for various needs.

Why doesn’t Tupperware dry in the dishwasher?

The reason why Tupperware doesn’t dry properly in the dishwasher lies in the difference in heat retention between plastic and other materials. While glass, ceramic, and metal retain heat effectively, allowing for drier dishes, plastic is less dense and cannot hold onto heat as efficiently. As a result, Tupperware containers are unable to reach the necessary temperature to dry thoroughly in the dishwasher, which can be a bit frustrating.
