Before using, we recommend:

- thoroughly wash your bottle and lid in hot mild soapy water, rinse well and dry

- make sure the seals are fitted correctly to avoid leakage

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

- Use white distilled vinegar for cleaning:
You can use household white distilled vinegar to help remove any stains or discolouration 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 the paste into the affected area on the inside of your bottle.  Repeat as necessary until stain disappears.

- Lime / Hard Water scale build up:
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.

- Metal Taste:
If your bottle gets a metallic taste, add 1 tsp of baking soda and warm water to help remove any taste or odour, cleanse and refresh your bottle. 

- Wooden Lids:
To help protect and extend the life of bamboo parts fitted to lids or bottles, it is recommended to treat with mineral oil or beeswax with mineral oil regularly.

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

- WARNING:
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.

Do not use abrasive cleaners or products on your ECOtanka.
Scourers, steel wool, acids, bleaches etc can damage the steel.

Don’t put thermoTANKA (vacuum) bottles in a dishwasher.  
The dishwasher could affect the insulation property of your bottle.

Don’t put painted bottles in a dishwasher.  
The dishwasher could remove the paint/logo from your bottle.

Don’t put your bottle in the freezer.
Add ice cubes to your drink bottle instead. Freezing can damage a stainless steel bottle.

Don’t put your bottle in a microwave.

Don’t overfill your thermoTANKA (vacuum) bottle with hot water.

Don’t put hot water in a single-wall bottle.
Single-wall bottles are not designed for hot liquids and you may get burnt.  

Don’t leave water in your bottle for long periods.
Water can become unsafe to drink if left stagnant. The more heat and light, the quicker the algae growth so water bottles left in the sun or for long periods can contain unsafe levels. Follow the cleaning and hygiene directions.

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

Keeping liquids cool:
Fill your stare bottle the night before and leave in the fridge overnight. Then add ice blocks before you go out in the morning. Using a Thermo bottle or Kooler Kovers helps immensely!

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