The convenience of throwing all our dishes into the dishwasher after a meal is undeniable. It saves time, effort, and water compared to washing them by hand. However, not all items are created equal when it comes to withstanding the high temperatures, harsh detergents, and intense water jets inside a dishwasher. One common question that arises is what happens if you put a metal tumbler in the dishwasher. To answer this, let’s delve into the world of dishwashing, materials science, and the specifics of metal tumblers.
Understanding Metal Tumblers
Metal tumblers have become incredibly popular due to their durability, thermal insulation properties, and aesthetic appeal. They are often made from stainless steel, aluminum, or a combination of metals, each with its own set of characteristics. Stainless steel tumblers, for instance, are known for their resistance to corrosion and ability to keep drinks hot or cold for hours. Aluminum tumblers are lighter and might be more prone to scratches but are also good insulators. The construction and finish of these tumblers (whether they are powder-coated, painted, or left in their natural metal state) play a significant role in how they will react to being washed in a dishwasher.
Materials and Finishes
The material and finish of a metal tumbler are crucial when considering dishwasher safety.

Aluminum, while lightweight and a good conductor of heat, can be more fragile than stainless steel. It may react with acidic substances, including some dishwashing detergents, potentially leading to corrosion or the leaching of metals into food and drink.
–
Coatings and Finishes
Many metal tumblers come with a variety of coatings or finishes, such as paint, powder coating, or a clear lacquer. These finishes can provide additional protection against corrosion and enhance the aesthetic appeal of the tumbler. However, they can also be vulnerable to chipping, fading, or peeling when exposed to the harsh conditions inside a dishwasher.
Dishwasher Effects on Metal Tumblers
When a metal tumbler is placed in a dishwasher, several factors can affect its integrity and performance. These include:
–
Temperature
Dishwashers can reach extremely high temperatures, especially during the drying cycle. While stainless steel can generally withstand these temperatures, aluminum or coated tumblers might not fare as well. High heat can cause coatings to degrade, metals to weaken, or the insulation properties of the tumbler to be compromised.
–
Detergents and Chemicals
Dishwashing detergents are designed to cut through grease and food residue. However, they can be harsh on some materials, potentially causing corrosion on metals like aluminum or damaging the finish of coated tumblers.
–
Water Pressure and Jets
The water jets in a dishwasher are powerful and can dislodge loose particles or debris. For metal tumblers, especially those with a powder coat or paint finish, these jets can be damaging, leading to scratches or chips in the finish.
Risks and Potential Damages
Putting a metal tumbler in the dishwasher poses several risks:
