before use

It is recommended to thoroughly wash your bottle and lid in hot mild soapy water, rise well and dry before use.

Make sure all silicone seal(s) have been fitted correctly to your lid before use to avoid leaking.  

For all thermoTANKA (vacuum) bottles, it is recommended to preheat your bottle before filling with your beverage for better heat retention.  Fill bottle with hot water, stand for 3-5 minutes, remove water and fill. 

After each use wash your bottle in warm water and give a mild scrub with a bottle brush cleaner.  

NOTE: When cleaning your bottle or lid, we recommend not to submerge or soak your bottle or lid in water.  We recommend the old fasion way, a quick hand wash and rinse, then dry.  


cleaning and care

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 bottle. We recommend putting ½ cup of vinegar in your bottle, gently swirling the vinegar around to wash any affected areas and let sit for 5 - 15 minutes.  Rinse thoroughly with warm water and repeat if necessary.

Use baking soda for cleaning: For those stubborn spots inside your bottle, mix 2-3 tablespoons of baking soda with a small amount of warm water to form a scrubbing paste.  Dip the bristles of your bottle brush in the paste and work paste into affected area on the inside of your bottle.  Repeat as necessary until stain disappears.

If you have been using your ECOtanka bottle for alkaline water and there is a build-up of white calcium deposit, it may be cleaned with citric acid from the baking section of your local supermarket.  Citric acid is the acid from citrus fruits.

If your bottle gets a metalic taste, add 1 tsp of baking soda and warm water to help remove any tatse or odour, cleanse and refresh your bottle. 

To help protect and extend the life of bamboo parts fitted to lids or bottles, it is recommended to treat with mineral oil or bees wax with mineral oil regularly.

This product is supplied as a drink bottle only and is not intended for any other use. Please use this product as you would responsibly use a drink bottle and for safe consumption item only.
