Are Bentgo Boxes Dishwasher Safe: A Comprehensive Guide

In today’s fast-paced world, convenience and efficiency are key factors in choosing our daily essentials. This also applies to meal prepping and packing lunches. Bentgo boxes have gained popularity as a sleek and practical solution for carrying meals on the go. However, an important question often arises: Are Bentgo boxes dishwasher safe? In this article, we’ll dive into the details to help you understand whether these stylish containers can withstand the dishwasher.

The Dishwasher Safe Debate

Bentgo boxes are designed with a combination of style and functionality, making them a favorite among meal preppers and lunch enthusiasts. The question of whether they are dishwasher safe, however, has generated discussions among users.

Manufacturer’s Guidelines

Bentgo, the company behind these innovative lunch boxes, provides guidance on how to care for their products. According to their guidelines, most Bentgo boxes are not dishwasher safe. The heat and pressure in dishwashers can potentially cause warping, cracking, and deterioration of the sealing gaskets. It’s essential to check the packaging or the official website to determine if your specific model is an exception to this rule.

Real-Life Experiences

While the manufacturer’s guidelines are crucial, many users have shared their personal experiences with dishwasher cleaning. Some users claim to have successfully washed their Bentgo boxes on the top rack of the dishwasher without any issues. However, it’s important to note that individual results may vary based on dishwasher models, water temperatures, and detergent choices.

Decoding Dishwasher Safety

To understand the dishwasher safety of Bentgo boxes, let’s delve into the types of Bentgo boxes available and their material composition.

Types of Bentgo Boxes

Bentgo offers a variety of models to cater to different preferences and needs. The most common ones include the Classic Bentgo, Bentgo Kids, and Bentgo Fresh. Each model features a unique design and layout, which may affect their dishwasher compatibility.

Material Composition

Bentgo boxes are primarily made from two materials: plastic and rubber. The plastic used is generally food-grade and BPA-free, ensuring the safety of your meals. The rubber elements are often present in the form of airtight seals and latches, which contribute to the box’s leak-proof design.

However, exposure to high temperatures and aggressive detergents in dishwashers can potentially degrade these materials over time. Warping, discoloration, and loss of airtightness are concerns to keep in mind.

Dishwasher Dos and Don’ts

If you decide to put your Bentgo box in the dishwasher, here are some tips to consider:

Proper Loading Techniques

Place the Bentgo box on the top rack of the dishwasher to minimize exposure to high heat and pressure. This can help prevent warping and damage to the airtight seals. Additionally, avoid overcrowding the dishwasher to allow proper water circulation.

Avoiding High Temperatures

Choose a gentle or eco-friendly cycle with lower water temperatures. High heat settings can accelerate the deterioration of materials, especially the rubber components. Steer clear of heated drying cycles as well.

Maintaining Bentgo Boxes

While the dishwasher may offer convenience, it’s worth considering the long-term durability of your Bentgo box.

Hand Washing vs. Dishwasher

Hand washing your Bentgo box with mild soap and lukewarm water remains the safest option for preserving its quality. This ensures a longer lifespan and maintains the box’s appearance and functionality.

Longevity and Durability

Regular use of the dishwasher might lead to a shorter lifespan for your Bentgo box. The heat and chemicals in dishwashers can gradually degrade the materials, affecting their performance and aesthetics.

Alternatives to Dishwashing

If you’re concerned about the impact of dishwashing on your Bentgo box, there are alternative methods to consider.

Hand Cleaning Methods

Gently clean the box using a soft cloth or sponge. Pay special attention to the sealing gaskets and corners to remove any food residue. Rinse thoroughly and allow it to air dry.

Sanitizing and Maintenance

Periodically sanitize your Bentgo box using a mixture of water and vinegar. This natural solution helps eliminate odors and bacteria, ensuring your meals remain fresh and safe.

Preserving Food Quality

One of the primary concerns with using dishwashers for Bentgo boxes is the potential impact on food quality.

Impact on Food Taste

Deterioration of materials and exposure to high temperatures can alter the taste and texture of your meals. To enjoy the best dining experience, it’s recommended to hand wash your Bentgo box.

Ensuring Freshness

Bentgo boxes are designed to keep your meals fresh and appetizing. Proper care, including avoiding dishwashers, can help maintain the box’s integrity and ensure your food remains as delicious as when it was packed.

Expert Opinions on Dishwasher Safety

Nutritionists and environmental experts offer insights into the dishwasher safety of Bentgo boxes.

Nutritionists’ Views

Nutritionists highlight the importance of maintaining the quality of your meals. They suggest that hand washing is preferable to avoid potential chemical leaching and to preserve the nutrients in your food.

Environmental Considerations

From an environmental standpoint, hand washing is the more sustainable option. Conserving energy and water aligns with eco-friendly practices, making a positive impact on the planet.

Making Your Decision

Choosing between using a dishwasher and hand washing your Bentgo box depends on your priorities and lifestyle.

Weighing Convenience vs. Safety

While dishwashers are convenient, they may compromise the longevity of your Bentgo box. If convenience is your top priority, consider models specifically labeled as dishwasher safe.

Catering to Individual Lifestyles

For individuals who value sustainability and product longevity, hand washing is the recommended choice. This ensures your Bentgo box remains in optimal condition for a longer period.


In the debate over whether Bentgo boxes are dishwasher safe, the answer is nuanced.
