In our race to save the environment and reduce the single-use plastic waste we produce, stainless steel water bottles have been a quick and easy solution. Cheers to you if you recently joined the movement and started using stainless steel water bottles too. But did you know there’s a proper way of cleaning these bottles to make sure they’re sanitised all the way? Here are some tips to help you thoroughly clean your stainless steel water bottles.

Use Distilled White Vinegar for Cleaning

White vinegar is a fantastic cleaning agent and not just for stainless steel bottles. White vinegar is a clear solution with the proper acidity levels that can easily cut through grease, grime, and other nasty bacteria. You can even reach those corners and other moist spaces in your bottle when using it.

If you’re starting to get that metallic or musty smell, that’s a good indication that your water bottle already needs some cleaning. Put around two tablespoons of vinegar inside the bottle, place the cap back on, and shake vigorously for a few seconds. After that, just pour it out and rinse the bottle with water.

Take a Cloth to the Cap

The bottle cap is perhaps the hardest thing to clean in a typical stainless steel bottle. That’s because it usually has those small corners and crevices where all the grime tends to build up. Your stainless steel bottle may look clean and shiny, but the insides of your bottle cap could be crusted in mildew and are already swarming with bacteria. Using white vinegar again, soak a clean cloth in the solution and use it to clean those unreachable corners that require scrubbing. After scrubbing for a while, just let the cap soak up the vinegar from the cloth for about 15 minutes before rinsing it out. 

Hydrogen Peroxide Also Works

If you start to see some grime and mildew buildup on the bottle, hydrogen peroxide works great in sanitising and cleaning your water bottle. Chances are you already have some hydrogen peroxide lying around, especially if you have a first aid kit at home.

A bottle of hydrogen peroxide with 35% H202 and a 65% water concentration is the perfect solution. This is already considered food-grade hydrogen peroxide, making it safe to use in your stainless steel water bottles. Just rinse your bottle with hot water and apply the solution inside while scrubbing it with a bottle brush. After scrubbing, just rinse it with hot water again, and you’re good to go.

Baking Soda as an Alternative

If you’re not a fan of the vinegar or hydrogen peroxide option, you can always use baking soda as an alternative. It has antimicrobial properties, just like white vinegar, but without a sour smell. Baking soda is great for eliminating any harsh odours caused by bacteria and mould. You can clean your bottle by putting about a teaspoon of baking soda inside it, then fill it with some water. While the solution is still inside the bottle, use a bottle brush to scrub the inside of the bottle. It’s also recommended to scrub the inside of the bottle cap with the baking soda solution too. Let the bottle sit overnight with the solution, and then rinse it out with water the following day. 

Conclusion

Reusable water bottles are not only great for the planet but even your health. Just make sure you clean and sanitise them thoroughly so you don’t end up consuming the bacteria and mildew that might’ve settled in your bottle. These cleaning tips are all safe and easy ways of cleaning your stainless steel water bottles.
