Most stainless steel water bottles can go in the dishwasher, but insulated thermos and bottles with plastic parts better not. The high temperatures and aggressive dishwashing agents can damage the insulation and deform plastic parts. Manual cleaning with warm soapy water is often the safest option for all water bottles.
Which water bottles can and cannot go in the dishwasher?
Stainless steel water bottles without insulation are usually dishwasher safe, while insulated bottles, plastic bottles and bottles with rubber parts are better cleaned manually. The material and construction will determine whether your bottle can handle the dishwasher.
Single-wall stainless steel bottles usually tolerate the dishwasher well. They are sturdy enough to withstand the high temperatures and vigorous rinsing. Just be sure to place them in the top rack, where temperatures are slightly lower.
Insulated thermo bottles have a double wall with vacuum in between. The heat and pressure in the dishwasher can damage this vacuum, causing your bottle to lose its insulating properties. Also, the adhesives that hold the different layers together can loosen.
Plastic water bottles are usually not dishwasher safe. The high temperatures can deform, discolor or even melt the plastic. Even BPA-free plastic bottles can lose their shape at the high temperatures.
Glass water bottles can often go in the dishwasher, but pay close attention to the lids and other parts. Rubber rings, plastic lids or metal parts can damage or lose their shape.
What happens if you put the wrong bottle in the dishwasher?
Wrong bottles in the dishwasher can be permanently damaged by deformed plastic parts, loss of insulation, loose lids and broken seals. The damage is often only noticeable after use, such as leaks or loss of temperature retention.
Plastic parts such as lids, drinking spouts and rubber seals can shrink, expand or deform. This causes them to no longer seal properly, which can lead to leakage. You often don't notice this until you fill your bottle and it suddenly leaks in your bag.
With insulated bottles, the vacuum between the walls can be lost. Your bottle will then no longer keep your drink hot or cold. You notice this because the outside of your bottle feels hot or cold when you put a hot or cold drink in it.
The glue that holds different parts together can loosen due to high temperatures. Lids can loosen, handles can break off and decorative elements can come off. Sometimes this happens only after several washings.
Some bottles get white stains or discoloration from the dishwashing agents. These stains usually don't go away and can make your bottle look old and dirty, even if it is clean.
What's the best way to clean your water bottle without a dishwasher?
Manual cleaning is best done with warm soapy water and a bottle brush. First rinse with warm water, add a drop of dish soap, brush well and rinse thoroughly. For stubborn odors, vinegar or baking soda will help.
Always start by emptying and rinsing your bottle with warm water. This removes most of the dirt already and makes the actual cleaning more effective. Use water of about 40-50 degrees, not boiling hot.
Add a small amount of dish soap to your bottle and fill it halfway with warm water. One drop is enough - more soap will only make rinsing more difficult. Screw on the cap and shake well.
Use a long bottle brush to thoroughly brush the inside. Pay particular attention to the bottom and threads where dirt likes to accumulate. Special curved brushes are available for narrow necks.
For stubborn odors or stains, you can use natural cleaners. Fill your bottle with warm water and add two tablespoons of white vinegar. Let this soak for a few hours and then rinse well. Baking soda also works well: make a paste of baking soda and water, brush with this and rinse thoroughly.
Always rinse thoroughly with clean water until there is no soap or vinegar residue. Let your bottle dry completely before putting on the cap to prevent mold.
Which retulp water bottles are dishwasher safe?
Our stainless steel water bottles without insulation can go in the dishwasher, but we recommend manual cleaning for all bottles to extend their life. Our insulated thermo bottles and biobased water bottles are best cleaned by hand.
We make different types of water bottles, each with their own care recommendations. Our single wall stainless steel bottles are the most robust and can technically go in the dishwasher. Still, we recommend manual cleaning because it is gentler on the material and any coating.
Our insulated thermo bottles have a clever double wall construction that keeps your drinks hot or cold for hours. This insulation can be damaged in the dishwasher, so always clean them by hand. That way you'll preserve the insulating effect to the fullest.
Sugar cane biobased water bottles are a sustainable alternative to plastic, but they are also best cleaned manually. The natural material does not tolerate aggressive dishwasher detergents as well as traditional plastic.
For all our bottles, rinse with warm water immediately after use, especially after sweet or sour drinks. This prevents stains and odors. For thorough cleaning, use warm soapy water and a bottle brush.

Frequently Asked Questions
How do I know if my water bottle is really dishwasher safe?
Look on the bottom of your bottle for symbols or text that indicate dishwasher safety. If there is no clear indication, contact the manufacturer. When in doubt, manual cleaning is always the safest choice to avoid damage.
My insulated bottle accidentally went into the dishwasher - is it salvageable?
Test if the insulation is still working by putting hot water in it and feeling if the outside gets warm. If the outside stays cool, the insulation is still working. If the outside is warm, then the vacuum is damaged and it is better to replace the bottle.
What natural alternatives are there to chemical cleaners?
Besides vinegar and baking soda, you can also use lemon juice against limescale and odors. Soaking pine cone peels in warm water gives a fresh scent. Rice with a little water and shake helps with stubborn stains because of its abrasive action.
How often should I thoroughly clean my water bottle?
For daily use for water: clean thoroughly 2-3 times a week. If you use your bottle for other drinks such as smoothies or sports drinks, then clean thoroughly after each use. Always rinse with warm water immediately after use.
What do I do if my water bottle has developed a foul taste or odor?
Fill the bottle with warm water and add 2 tablespoons of baking soda, leave overnight and rinse thoroughly. For very stubborn odors: mix warm water with white vinegar (1:1 ratio) and leave for 24 hours before rinsing out.
Can the lids and drinking spouts go in the dishwasher, even if the bottle itself can't?
This depends on the material of the parts. Stainless steel lids usually can, but plastic lids, rubber rings and silicone parts better not. Always check the manufacturer's instructions for specific parts.
How do I prevent mold and bacteria in my water bottle?
Always let your bottle dry completely before putting on the cap. Store it open in a ventilated area. Clean regularly and thoroughly, especially the screw threads and hard-to-reach corners where moisture can remain.
