Experts suggest reusable water bottles should be washed each time after use. Tetro said you can rinse your bottle with hot water over 71 C. With temperatures of about 55 C, use soap with some kind of cloth or sponge and make sure you're giving your bottle a thorough rinse. Dry your water bottle after that.

Try to keep acidic drinks like tea & coffee for no more than 2 hours to avoid damaging the coating in the bottle.

Brush the inside of your bottle regularly with a small bottle brush and water.

If the inside of your bottle is starting to look, feel or smell of anything other than stainless steel you may like to try one of these options on a weekly basis to remove stubborn stains and discolouration.
