Are Stanley Tumblers Dishwasher Safe? A Comprehensive Guide

Stanley tumblers are renowned for their rugged durability and excellent temperature retention capabilities. These iconic stainless steel tumblers are a favorite among outdoor enthusiasts, commuters, and anyone who values a good quality drinkware. However, one common question that arises among Stanley tumbler owners is whether these tumblers are dishwasher safe. In this comprehensive guide, we will explore the various aspects of Stanley tumblers’ dishwasher safety.

Understanding Stanley Tumblers

Before we delve into the dishwasher safety of Stanley tumblers, let’s understand what makes these tumblers so popular:

  1. Material: Stanley tumblers are typically constructed from high-quality 18/8 stainless steel. This material is known for its corrosion resistance, toughness, and ability to keep beverages at the desired temperature for extended periods.
  2. Vacuum Insulation: The tumblers feature double-wall vacuum insulation that helps in maintaining the temperature of both hot and cold beverages. This means your coffee stays hot for hours, and your cold drinks remain refreshingly chilled.
  3. Durability: Stanley tumblers are built to withstand tough conditions. They are designed to be rugged, making them ideal for outdoor adventures, camping trips, and daily use.
  4. Easy-to-Clean Design: Stanley tumblers often have a wide-mouth design, making them easy to clean by hand. But what about using a dishwasher?

Are Stanley Tumblers Dishwasher Safe?

Stanley tumbler owners may wonder whether they can toss their favorite drinkware into the dishwasher for a hassle-free clean. The short answer is, it depends.

Stanley, in its product care instructions, recommends hand washing for best results. While some Stanley tumblers may survive occasional trips through the dishwasher, there are reasons to exercise caution:

  1. Harsh Detergents: Dishwashing detergents can be abrasive and might affect the tumbler’s exterior finish over time. This could result in a loss of the tumbler’s original luster.
  2. Vacuum Seal: Stanley tumblers have a vacuum seal between the outer and inner walls. The extreme heat and moisture in the dishwasher can potentially compromise this seal over time, affecting the tumbler’s insulating abilities.
  3. Color Coating: Some Stanley tumblers feature colored coatings. Repeated exposure to the high heat of the dishwasher may cause these coatings to fade or peel.

Tips for Dishwashing Stanley Tumblers

If you choose to wash your Stanley tumbler in the dishwasher despite the manufacturer’s recommendations, here are some tips to minimize potential damage:

  1. Use the Top Rack: Place your tumbler on the top rack of the dishwasher. This reduces exposure to high heat.
  2. Avoid High Temperatures: Use a gentle or low-temperature setting on your dishwasher to prevent excessive heat exposure.
  3. Hand Wash Accessories: Remove any additional components like lids, gaskets, or straws and wash them by hand to extend their lifespan.


In conclusion, while Stanley tumblers are renowned for their durability and ruggedness, they are not explicitly designed for dishwasher use. The manufacturer recommends hand washing to ensure the longevity and performance of your tumbler. However, if you choose to use a dishwasher, follow the tips mentioned above to minimize potential damage. Ultimately, proper care and maintenance will help you enjoy your Stanley tumbler for years to come, whether you choose to wash it by hand or in the dishwasher.
