If you’re using your stainless steel water bottle every day, there are a few daily tasks you should do to keep your bottle in top condition.

Make sure the lid is completely dry before putting it back on the bottle though so it doesn’t become a breeding ground for germs!

Also, wash the bottle out thoroughly using warm water and soap. To get into those tricky nooks and crannies you can use a cloth or a small brush to scrub the inside and remove any build up. Rinse the bottle out thoroughly and again leave it to dry completely before using it again.

Best equipment to clean your bottle with

How to Clean a Stainless Steel Bottle in 3 Ways (4)

Washing your stainless steel water bottle is a quick and simple process that doesn’t require a lot of equipment. In fact, you’ll no doubt already have everything you need already laying around your kitchen! You can use a cloth to clean both the inside and the outside of the bottle, but, if you really want to be able to get in those hard-to-reach places then the best piece of equipment to use would be a water bottle brush.


Water bottle brushes are narrow, flexible brushes with long handles allowing easy access inside the bottle. Their soft bristles are perfect to use for stainless steel bottles as they won’t scratch the inside, unlike other products such as metal scrub sponges and wire brushes.

How to clean your bottle brush

After a few uses you’ll need to also clean your bottle brush too so no germs can build up and no residue or scents of previous drinks will linger.

  • First fill the sink with hot water and add 1tbsp of liquid soap.
  • Let your brush soak in the water for about 10/15 minutes first as this will loosen any product that may be stuck to it.
  • Gently separate and comb through the bristles to remove any dirt particles and ensure the soap covers the entire brush.
  • Rinse the brush off in the hot water and leave it on the side to dry.
  • If you want to go that extra step farther and sanitise your brush, place it in a clean bowl and pour hydrogen peroxide over it to kill any lingering germs.
  • Leave the hydrogen peroxide on for another 10/15 minutes before rinsing it and letting it dry.
