You did a great job by searching on the web regarding metal water bottles and their safety in dishwashers. Improper cleaning of metal water bottles can cause minor to major damages to the bottles. So, are metal water bottles dishwasher safe?
Metal water bottles can be dishwasher safe, but it depends on the type. Single-wall stainless steel and titanium bottles usually handle dishwashers well. However, insulated, aluminum, and copper bottles should be hand washed to prevent damage.
Keep reading to learn long, well-described answers so there’s no chance of damaging your favorite metal water bottle!
How Does A Dishwasher Clean Metal Bottles?
Dishwashers clean dishes by spraying hot water and detergent onto them. Here’s how it works:
- Load the dishes into the racks and add detergent.
- Start the dishwasher. It fills with water and heats it.
- A pump sprays hot water mixed with detergent onto the dishes through rotating spray arms, removing food particles and stains.
- After washing, the dishwasher drains the dirty water and rinses the dishes with clean water.
- Finally, the dishwasher dries the dishes using hot air or a fan.
This process can affect metal water bottles in different ways. We will discuss it in the next sessions.

Are Metal Water Bottles Dishwasher Safe?
Here you will find detailed facts about different types of water bottles and their dishwasher safety levels.
Stainless Steel Water Bottles
Single-wall stainless steel water bottles are safe to wash in the dishwasher. Since they don’t have any insulation or coating, there’s less risk of damage. Still, place them on the top rack (where the temperature is the lowest), as high heat can cause discolouration over time.
Things are different for double-wall and triple-wall stainless steel water bottles.
You should always handwash these two types of water bottles. The high temperature in the dishwasher can damage the vacuum seal between the walls of insulated water bottles. It will reduce the insulation efficiency of your water bottle over time.
Also, bottles with a powder coating finish or paint can get damaged or fade. So, it’s best to wash these two types of stainless steel water bottles gently by hand.
Aluminum Water Bottles
Aluminum water bottles are not dishwasher-safe. High temperatures and harsh detergents in dishwashers cause several issues with aluminum bottles.
- Firstly, manufacturers line aluminum bottles with a protective coating to prevent the metal from reacting with the contents inside. Dishwashers damage this coating and expose the raw aluminum. When exposed, aluminum reacts with dishwasher detergents and water. It leads to corrosion and potential contamination of the contents.
- The dishwasher heat causes thermal expansion, which darkens or discolors the aluminum. This ruins the bottle’s aesthetics and affects its durability. Aluminum also oxidizes when the protective layer is damaged. It further degrades the bottle.
- Another concern is the design of aluminum bottles. Their narrow interior makes it difficult for the dishwasher to clean them thoroughly. The rubber gaskets in the bottle caps degrade quickly due to the high heat. It eventually causes leaks and reduced effectiveness.

Copper Water Bottles
Copper water bottles are not dishwasher-safe, sorry.
The exterior of copper bottles often has a food-safe lacquer that gives them a shiny appearance. Dishwashing strips this lacquer and exposes the copper underneath to oxidation.
This exposure leads to dark spots and a dull finish. Also, the harsh environment inside a dishwasher can damage or dull the intricate designs and patterns on many copper bottles.
Handwashing is the best method for cleaning copper water bottles. Use mild soap and warm water to clean the bottle’s inside and outside. Avoid abrasive scrubbers or harsh chemicals, as they can scratch and damage the surface.
Titanium Water Bottles
Titanium water bottles are safe for dishwashers. Titanium is a highly durable and corrosion-resistant metal, which means it can withstand the high heat and strong detergents used in dishwashers without getting damaged.
However, always check the manufacturer’s instructions before placing your titanium bottle in the dishwasher. Some bottles have additional coatings or painted designs that could get damaged in a dishwasher.
If your bottle has any extra features like rubber seals or insulation, hand wash those parts to maintain their effectiveness and longevity.
General Guidelines About Dishwashing Safety
To determine if your insulated water bottle can go in the dishwasher, look for the dishwasher-safe symbol. This symbol is usually on the bottom of the bottle or in the product manual. It shows that the bottle can safely handle dishwasher conditions.

The symbol often looks like a square box with dishes and water droplets or lines. This indicates the product can withstand dishwasher conditions.
Do not forget to check for this symbol before washing your water bottle in the dishwasher. This ensures you keep your bottle in good condition and avoid any damage.
Best Practices to Wash Metal Water Bottles
These tips will help you preserve the powder coating or metal finish on the water bottles.
Stainless Steel Water Bottles:
- Use warm water and mild soap for regular cleaning. Avoid abrasive scrubbers to prevent scratches.
- Most single-wall stainless steel bottles can go in the dishwasher, but place them on the top rack to avoid high heat.
- For a thorough clean, use a mixture of baking soda and vinegar. Let it sit for 15-30 minutes, then scrub with a bottle brush and rinse thoroughly.
Aluminum Water Bottles:
- Use warm water and a few drops of pH-neutral dish soap. Avoid using the dishwasher as it can damage the protective coating.
- Combine 3 tablespoons of lemon juice or white vinegar with water. Shake and let it sit for 10 minutes, then scrub with a bottle brush.
- Dry the bottle upside down with the cap off to prevent moisture build-up and bacterial growth.
Copper Water Bottles:
- Use warm water and mild soap. Avoid harsh chemicals and abrasive scrubbers.
- Use a lemon slice sprinkled with salt to rub the surface. Rinse and dry thoroughly to maintain shine.
- Do not pour very hot liquids or freeze the bottle, as it can damage the copper lining.
- Always dry the bottle after washing to prevent oxidation and maintain its appearance.
Titanium Water Bottles:
- Use warm water and mild soap for regular cleaning. Titanium is highly durable and resistant to corrosion.
- Most titanium bottles can go in the dishwasher. Place them on the top rack for best results.
- For everyday use, rinse with water to keep it clean and odour-free.
FAQs
How Often Should You Wash a Metal Water Bottle?
Wash your metal water bottle daily. Clean it with warm water and mild soap to remove bacteria and residue. If you use it for drinks other than water, wash it immediately after use. For a deep clean, use a mixture of baking soda and vinegar once a week. Regular cleaning keeps your bottle safe and fresh.
How Long Can Water Sit in Metal Bottles?
You can store water in a clean stainless steel bottle for months, depending on the water’s purity. However, if you don’t clean your bottle regularly, avoid storing water in it for more than a few days to prevent bacteria growth. Regular cleaning ensures your water stays safe to drink.
How to Get Rid of Smell in a Metal Water Bottle?
Use vinegar to get rid of the smell in a metal water bottle. Pour in two tablespoons of vinegar, cap the bottle, and shake well for a few seconds. Pour out the vinegar and rinse the bottle thoroughly with water. This helps eliminate any metallic or musty odors.
