Can Insulated Cups Go In The Dishwasher? (Explained)

Insulated cups have seals that are prone to breaking because of the heat in your dishwasher. Hot water can get between the outside and the interior insulated wall, making them sloshy and sometimes ruining them forever.

This is why manufacturers placed ‘hand wash only’ and ‘not dishwasher safe’ on the label of your insulated cups when you bought them. 

Can Insulated Cups Generally Go In A Dishwasher? 

Once the seal is broken, it will negate the insulation ability of your cup. 

Even a tiny break will affect the vacuum inside the cup, significantly reducing its insulation. The hot temperature inside the dishwasher causes plastics to flatten or warp. 

Let’s get a better understanding of how insulated cups work:

How Insulated Cups Work:

Insulated cups have air in between the inner and outer shells. From there, the vacuum is created. 

However, your dishwasher can potentially break this seal, allowing the moisture to come in, damaging the cup. 

When the seal is compromised, the water can get inside the cup’s inner and outer skin, and there’s no way of taking them out. The sloshing water will eventually become annoying the longer you use the cup. 

Make sure that you are handwashing all cups that require it. Keep your favorite cups out of the dishwasher.

How Do I Know If My Insulated Cup Can Go In The Dishwasher?

Not every insulated cup is safe in your dishwasher. 

Putting them into the dishwasher might compromise their insulation, nullifying their effectiveness in retaining your drink’s temperature. 

This is why you need to know if your insulated cup can go in the dishwasher. Moreover, choosing non-dishwasher-safe drinkware will seem like a chore at times.

When buying dishwasher-safe insulated cups, it would be best to look for these things:

  1. Know the materials that are good for dishwashers 
  2. Assess which type of drinkware you should wash 
  3. Find the “dishwasher safe” note on the label 

In addition, dishwasher-safe drinkware will always have the “Dishwasher Safe” symbol printed on the item. 

Also, the symbol doesn’t always look the same. Sometimes, they are in the form of a rack or drenched in water. 

Why Can Insulated Cups Turn Black In The Dishwasher?

Not all insulated cups are created equal. Some are dishwasher-safe than others. 

According to Kitchen Appliances and Technology Lab director Sharon Franke, your dishwasher can potentially ruin the insulation of your insulated cups. Remember, your insulated cup is an essential travel item that you should always secure. 

A little more work like handwashing will go a long way instead of trying to take the easy route to the dishwasher, right? 

Likewise, you might find your favorite companion turning a little bit black after a couple of trips to the dishwasher. This is often the case for aluminum insulated cups. When this happens, you can use white vinegar and water. 

Mix them in a spray bottle and apply to the aluminum. Let it sit for a few minutes. Use steel wool and gently scrub the surface. 

Use more vinegar as needed.
