When it comes to cleaning our kitchen utensils and dinnerware, the dishwasher is often the go-to solution. It’s quick, convenient, and efficient. But, have you ever stopped to think about whether all items are created equal when it comes to the dishwasher? Specifically, what about stainless steel cups? Can they be safely washed in the dishwasher, or is it best to hand wash them instead?
The Importance of Understanding Stainless Steel
Before we dive into the reasons why stainless steel cups shouldn’t go in the dishwasher, it’s essential to understand the material itself. Stainless steel is a type of metal alloy that is resistant to corrosion and staining. It’s commonly used in cookware, cutlery, and, of course, cups.
There are different types of stainless steel, each with its own unique properties and characteristics. When it comes to cups, the most common types of stainless steel used are 18/8 and 18/10. The numbers refer to the percentage of chromium and nickel content in the alloy. 18/8 stainless steel contains 18% chromium and 8% nickel, while 18/10 stainless steel contains 18% chromium and 10% nickel.
What Makes Stainless Steel Cups So Special?
So, what makes stainless steel cups so special? For starters, they’re incredibly durable and resistant to scratches and corrosion. They’re also non-toxic, meaning they won’t leach harmful chemicals into your drinks. Additionally, stainless steel cups are:
- Easy to clean and maintain
- Resistant to extreme temperatures
- Non-reactive, meaning they won’t impart flavors or odors to your drinks
- Environmentally friendly, as they can be reused multiple times, reducing the need for single-use cups
The Risks of Washing Stainless Steel Cups in the Dishwasher
Now that we’ve covered the benefits of stainless steel cups, let’s talk about the risks of washing them in the dishwasher.
Thermal Shock
Thermal shock occurs when a material is exposed to rapid and extreme temperature changes. In the case of stainless steel cups, this can happen when they’re washed in the dishwasher. The intense heat and cold water can cause the metal to expand and contract rapidly, which can lead to:
- Warping or deformation of the cup

Harsh Chemicals and Detergents
Dishwasher detergents are designed to tackle tough food residue and stains on dishes. While they’re effective, they can be too harsh for stainless steel cups. The strong chemicals can:
- Strip away the cup’s natural passivation layer, leaving it prone to corrosion
- Cause discoloration or stains on the surface of the cup
- React with the metal, causing it to become brittle or weak
Physical Damage
The dishwasher can be a rough environment, with utensils and dishes bumping against each other during the cycle. Stainless steel cups can be damaged or scratched during the wash cycle, especially if they’re not secured properly. This can lead to:
- Scratches or dents on the surface of the cup
- Chips or cracks around the rim or handle
- Bent or warped handles or rims
The Benefits of Hand Washing Stainless Steel Cups
While it may seem like a hassle, hand washing your stainless steel cups is the best way to ensure they remain in good condition. Here are just a few benefits of hand washing:
Gentle Cleaning
Hand washing allows you to clean your stainless steel cups gently, without exposing them to the harsh conditions of the dishwasher. You can use a mild soap and warm water to clean the cups, without worrying about damage or corrosion.
Personalized Cleaning
When you hand wash your stainless steel cups, you can tailor your cleaning approach to the specific needs of the cup. If the cup has a stubborn stain, you can spend a little extra time soaking or scrubbing it. If the cup has a delicate handle or rim, you can take extra care to avoid damaging it.
Extended Lifespan
By hand washing your stainless steel cups, you can extend their lifespan and prevent premature wear and tear. With gentle cleaning and proper care, your cups can remain in good condition for years to come.
Additional Tips for Cleaning and Caring for Stainless Steel Cups
In addition to hand washing, here are some additional tips for cleaning and caring for your stainless steel cups:
Avoid Abrasive Materials
When cleaning your stainless steel cups, avoid using abrasive materials like scouring pads or steel wool. These can scratch or damage the surface of the cup.
Dry Your Cups Thoroughly
After washing and rinsing your stainless steel cups, make sure to dry them thoroughly. This will help prevent water spots and bacterial growth.
Store Your Cups Properly
When storing your stainless steel cups, avoid stacking them on top of each other, as this can cause scratching or damage. Instead, store them side by side or upside down to prevent water from collecting in the cups.
Conclusion
In conclusion, while stainless steel cups are incredibly durable and resistant to corrosion, they still require special care when it comes to cleaning. Avoid washing them in the dishwasher, as this can cause thermal shock, exposure to harsh chemicals, and physical damage. Instead, hand wash your cups using a mild soap and warm water, and take care to dry them thoroughly and store them properly. By following these tips, you can extend the lifespan of your stainless steel cups and keep them looking like new for years to come.
