Vacuum Insulated Thermos Bottle

How to prepare your thermos for first time use...

When you first purchase your new Lutom thermos please clean it  before use. Soak your bottle in soapy water, Rinse the thermos and cap well and your are ready to start your sustainable adventures! You can sanitize your bottle with a gentle run through the dishwasher, but it is recommended to hand wash to lengthen the life of your bottle and its insulation properties. 

How to Care for your thermos to insure longevity...

Keep your thermos clean: 
Wash your thermos with a non metallic bottle brush that will not scratch or damage the thermos.

Use white distilled vinegar for cleaning:
You can use household white distilled vinegar to help remove any stains or discoloration on the inside of your thermos. We recommend putting ½ cup of vinegar in your thermos, gently swirling the vinegar around to wash any affected areas, and let sit for 5 minutes. Rinse thoroughly with warm water and repeat if necessary.

Use baking soda for cleaning:
For those stubborn spots (e.g.: from coffee or wine) inside your thermos, mix 2-3 tablespoons of baking soda with a small amount of warm water to form a scrubbing paste. Dip the bristles of a bottle brush in the paste and work paste into affected area on the inside of your thermos. Repeat as necessary until stains disappear.

The active sip cap is top-rack dishwasher safe. The cap may last longer if it is hand washed, but if it needs to be deep cleaned, the dishwasher is acceptable.

What NOT to do with your thermos to insure longevity...

Do Not use bleach or chlorine to clean our products:
Those chemicals will ruin and rust stainless steel; therefore, they should not be used on our products.

Do Not Put your Thermos in the freezer:
Due to the double wall vacuum insulation, the water inside will be protected from the temperature inside the freezer and won’t freeze. If you want ice cold water, put some ice cubes inside your thermos and the insulation will keep your water cold all day.

Do Not Expose your thermos to a direct heat source:
Due to the double wall vacuum insulating property of the thermos, outside temperature will not change the inside beverage temperature. If you put your thermos on any sort of stove or heat source, the heat will damage the outside of the thermos.

Take caution: 
The natural wood of the bamboo cap may absorb water and wear out quicker when they are run through the dishwasher or submerged in water for an extended period of time. Instead, we recommend hand washing it with hot, soapy water, rinsing, and allowing it to air dry.

Take caution:
Excess heat from the dishwasher can get hot enough to affect the insulation property or possibly discolor the powder coat. Similarly, soaking your entire thermos in hot water for extended periods of time may also discolor the powder coat.

Bamboo Toothbrush

How to care for your bamboo toothbrush

The best place place to keep your bamboo toothbrush is in a dry area. Bamboo is a natural antibacterial hard wood but it is still a natural material that is designed to eventually break down and return to the earth. (Which makes it a great eco essential!)  Toothbrush cups that collect water are not recommended. You should keep your Lutom toothbrush in an open-air toothbrush holder or any other dry area.

First Use

 Rinse your toothbrush handle and bristles with water before its first use. There may be some fine bamboo dust that remains on the toothbrush head and handle after manufacturing. This is harmless but should be washed off. You can rinse and wash just like a conventional plastic toothbrush.


If cared for properly, your bamboo toothbrush will last just as long as a conventional plastic toothbrush. The American Dental Association recommends replacing your toothbrush every 3 months, or when the bristles have frayed.
