For best results please clean the inside of the i9 bottle with diluted white (alcohol) vinegar, which can be purchased at any general food store. Pour approx. 50 ml of diluted vinegar into the bottle and leave standing for 10 minutes, then rinse well with clean water.
Clean the outer surface of the i9 bottle using only clean water, ensuring never to put pressure directly on the tag. Do not clean using liquids containing alcohol or other abrasive solvents, which could damage or detach the tag from the bottle.
Food and protein shakes
Whenever using the i9 bottle for mixing protein shakes, smoothies or other similar drinks, which tend to leave more stubborn stains on the glass, we recommend cleaning your bottle with a special brush, which can be purchased at our on-line store. WARNING! DO NOT use metal brushes to clean the i9 bottle, as this may damage the surface of the bottle and void your guarantee.
After cleaning your i9 bottle with the brush, the brush itself must also be carefully cleaned, especially as particles of food can get stuck between the bristles, thus causing bacterial growth over time.
Do not wash the i9 bottle in a dishwasher, as this may damage the informed tag and the information contained on it.How to clean a bottle brush?Expand

Scrape food particles from between the bristles and rinse periodically under running warm water to remove all particles between the bristles.
Rinse in hot water.
