When to Clean a Stainless Steel Water Bottle?

It's ideal to clean Hydro Cell stainless steel water bottles once a day. However, these are the instances when you may need to do it a few times a day.

  • When you notice a bad smell: A bad odor usually happens when there's stagnant water. Additionally, the smell of the food you eat can transfer to the bottle. Worse, the bacteria from your mouth can also linger in the bottle, causing a foul odor. 
  • When you see a slimy film: Do you feel like there's something sticky whenever you touch the tumbler or press your lips against the bottle's neck? That's a sign it's time to wash your bottle.
  • When using the bottle outdoors: Do you carry a tumbler during a hike or gym workout? Even in a post-pandemic world, you should clean your bottle if you're using it outside. Don't keep it in your work or lunch bag overnight because the dirt or bacteria may transfer to your other items.
  • When you're pouring a variety of beverages: Powdered juice, tea leaves, or coffee grounds can leave a residue. Even pretreated water can contain pathogens or disease-causing organisms. There may be times when you refill a tumbler outside your home, and you're unsure if the café or office dispenser is using pretreated or inadequately treated water. 

How Dirty Are Stainless Steel Water Bottles?

An analysis from environmental testing firm EmLab P&K shows that water bottles carry approximately 300,000 colony-forming units of bacteria for every square centimeter. This equates to about 6 times the amount of bacteria found on pet bowls.

Bacteria form a biofilm or clusters of bacteria on the interior of reusable stainless steel water bottles over time. This is why it's vital to create a mechanical action to remove that film, and one way to do that is to wash your water bottles at least once a day. Hydro Cell water bottle and a wash cloth
