Did You Know?

1. Despite being commonly used in dishwashers, not all Tupperware containers are actually dishwasher safe. Some models can warp or lose their original shape when exposed to high temperatures, so it’s important to check the product labeling or manufacturer’s instructions before putting them in the dishwasher.

2. The invention of Tupperware was inspired by the durability and airtight nature of paint and pliable plastic lids used in World War II for sealing ammunition cases. Earl Tupper, the inventor, adapted this technology to create airtight food storage containers for household use.

3. Tupperware parties became popular in the 1950s as a way to sell these innovative food storage products. The parties were primarily hosted by women, providing them a social space where they could network, learn about the products, and have a fun social gathering at the same time.

4. Tupperware was featured in an episode of the popular television show “Mad Men.” The episode, titled “The Wheel,” showcased the protagonist’s pitch for a new ad campaign featuring Tupperware, illustrating the significance and cultural impact of Tupperware during the 1960s.

5. In 2004, Tupperware introduced a limited edition “Freeloader Fork” that featured a small spoon-like attachment on the handle.

However, the unconventional design did not gain widespread popularity and the product was eventually discontinued.

Tupperware Purchased After 1979: Dishwasher Safe

Tupperware has long been a staple in kitchens around the world, providing convenient storage solutions for leftovers and meal prepping. One common question that arises when using Tupperware is whether it is dishwasher safe. Thankfully, Tupperware made after 1979 is indeed dishwasher safe, making cleanup a breeze. This reassurance allows individuals to focus on other tasks while their Tupperware is being cleaned.

It is important to note that not all Tupperware products manufactured before 1979 are dishwasher safe. Therefore, it is advisable to check the manufacturing date for older containers to ensure their compatibility with the dishwasher. However, if your Tupperware was purchased after 1979, you can rest assured that it can withstand the heat and agitation of the dishwasher, making cleanup quick and efficient.

Identifying Dishwasher Safe Tupperware

When it comes to determining whether your Tupperware is dishwasher safe, there are a few indicators to look out for. Most Tupperware products are labeled as dishwasher safe, granting users peace of mind. However, in the absence of explicit labeling, there is another method to identify dishwasher safe Tupperware.

Look for a symbol on the Tupperware that indicates dishwasher safety. This symbol typically consists of a square box with plates or glasses inside, with lines or dots representing water. It is a universal symbol that is recognized across various brands and signifies that the container can safely be placed in the dishwasher. So, even if your Tupperware does not explicitly state its dishwasher compatibility, this symbol can help affirm its suitability for the dishwasher.

Washing Tupperware Without Dishwasher Safe Label

In cases where your Tupperware does not explicitly claim to be dishwasher safe and lacks the dishwasher safe symbol, it is best to err on the side of caution. It is recommended to either wash such containers by hand or place them on the top rack of the dishwasher. This precaution ensures that the Tupperware does not get damaged due to the intense heat or excessive agitation experienced in the lower racks of the machine.

By handwashing, you can use a mild dish soap and warm water to clean your Tupperware gently. This method allows you to have greater control over the cleaning process and ensures the longevity of your Tupperware. Alternatively, utilizing the top rack of the dishwasher provides a compromise between convenience and safety, allowing your Tupperware to be cleaned while minimizing potential risks.

Dishwasher Safety Of Other Plastic Food Container Brands

While Tupperware is a well-known brand for its durability and dishwasher-safe properties, there are other reputable brands in the market that also provide dishwasher compatibility for their plastic food containers. Some popular options include Rubbermaid, Snapware, and Lock&Lock. It is important to note that each brand may have specific care instructions, so it is essential to always check the bottom of each plastic food container for the recommended care guidelines. By following these instructions, you can ensure proper maintenance and longevity of your containers.

BPA in Tupperware: Potential Health Concerns

Alongside the convenient qualities of Tupperware, it is important to be aware of potential health concerns associated with certain types of plastic containers. Bisphenol A (BPA) is a potentially harmful chemical commonly used in the production of plastics. BPA has been shown to have negative effects on the development of the nervous system. Therefore, it is essential to identify if any Tupperware containers contain BPA to minimize potential risks.

To identify if your Tupperware containers contain BPA, look for characteristics such as being see-through, labeled “microwave-safe” or “unbreakable,” having Resin Identification Code number 7 on the bottom, or being labeled “hand-wash only.” Tupperware products that contain BPA should not be used for storing or microwaving food to avoid the leaching of this harmful substance. Instead, consider using glass containers as a safer alternative. Glass containers do not leach harmful substances, are dishwasher and microwave safe, and do not stain or wear out over time.

It is important to note that if you have old Tupperware containers suspected to contain BPA, they can still be useful for other purposes. Recycling or repurposing these containers ensures their usefulness while reducing the potential health risks associated with their use for food storage.

Frequently Asked Questions

Is it okay to put Tupperware in dishwasher?

However, for newer Tupperware, as long as it is labeled as “dishwasher safe,” it can be safely cleaned in the dishwasher. Nonetheless, it is imperative to always use the top rack, as the bottom rack’s proximity to the heating element can potentially cause melting and damage to your Tupperware containers.

Is Tupperware microwave and dishwasher safe?

Tupperware is designed to be dishwasher safe, allowing for convenient cleaning. However, when it comes to microwaving, it is advisable to exercise caution. While Tupperware can withstand the microwave’s heat, there may be concerns regarding potential bacterial growth. Therefore, it is recommended to avoid microwaving food in Tupperware to ensure food safety and minimize any potential risks.

What symbol means dishwasher safe?

The symbol that indicates dishwasher safe items usually consists of a square box, within which there are plates or glasses (or sometimes both). This symbol is commonly used for both top rack and generally dishwasher safe items. Additionally, you may find water droplets or diagonal lines alongside the box, indicating the presence of water.

Can you put Tupperware in bottom dishwasher?

It is important to always place Tupperware on the top rack of the dishwasher to avoid any potential damage.
