What Happens if You Put Stainless Steel Cups in the Dishwasher?
Stainless steel cups are not safe to put in dishwashers because the dishwasher’s detergent and extreme humidity tend to wear down the stainless steel.
Stainless steel cups are generally indestructible. They also have properties that make them resistant to wear and tear even with repeated use.
However, if you place them inside the dishwasher, the acid from the food soils will make them lose their polish.
By wearing down their durability, your stainless steel cup may hold watermarks or lose its ability to keep things hot and cold.
Can Stainless Steel Mugs Go in the Dishwasher?
Stainless steel mugs are made of the same materials, so they are also not safe to be cleaned in the dishwasher.
Insulated mugs made of stainless steel on the inside are not dishwasher safe. If you put them in the dishwasher, you will notice that the air-tight property will diminish and wear out after just a couple of washes.
Why Does Stainless Steel Turn Black in Dishwashers?
When stainless steel turns black, it has gone through an oxidation process called rouging.

Also, the detergent used may react badly to the stainless steel, causing it to turn black.
