Why You Should Clean Reusable, Eco Friendly Water Bottles

How often are you cleaning your water bottles? Have you ever?

If you’re like me, you are drinking out of yours constantly. They stay relatively clean, but bacteria from your mouth can transfer through the straw and get into the water bottle. Bacteria love moisture, so it’s very important to keep a clean bottle!

It feels even more important for me to keep a clean bottle for my kids. They are not as neat and tidy when it comes to drinking out of their water bottles, especially if they are drinking from them while eating. I can’t even count how many times I’ve gone to refill my kid’s stainless steel bottle and find food trapped in the straw, and inside the water bottle.

Water bottle cleaning regularly (for me about once a week), keeps our stainless steel water bottles clean and odor free! Especially with back-to-school right around the corner, my kid’s water bottles for school have been sitting in their backpacks all summer and need a very thorough cleaning.

Our Favorite Stainless Steel Bottle

I have had the best luck with Yeti water bottles! I love their 18-ounce Rambler and the Rambler Bottle Straw Cap. Personally, I prefer drinking from a straw, and the 18-ounce size fits perfectly in my car cupholder.

For my kids’ water bottles for school (and home!), their Rambler Jr 12-ounce Kids Bottle cannot be beaten. With 3 little boys, I have tried out every kid’s stainless steel bottle made, and the Yeti is definitely my favorite. I love that it has a hard straw, so my kids can’t chew threw it as they have with other silicone straw bottles. It is also completely leakproof when closed, though it does leak when it is open. It fits perfectly in a school backpack, and I love that I can add their name to it.

I also know a lot of people have success with aluminum water bottles, and this clean bottle hack will work for them too!

8. Air Dry.

Lay your eco friendly water bottles to air dry for several hours, or better yet, overnight. This is a very important step because you want the air to dry any moisture from the stainless steel or aluminum water bottles, which will also kill any bacteria that are lingering in the moist environment, especially in the lid and straw area.

Keeping a Clean Bottle FAQS

How often should I clean my stainless steel or aluminum water bottles?

It depends on how often you use it! In my house, we use them constantly and I have found that once a week works best for us.

Do you have a Branch Basics code?

Yes! Code TASTESLOVELY for 15% off any starter kit! Here’s my honest review of their products if you want more in-depth information!

Do you clean the kids’ water bottles for school more often?

Sometimes! Although I know what kind of wear and tear their stainless steel bottle goes through at home, and at school, I don’t always know where they end up. So, I check them daily when the kids get home and if they need a quick water bottle cleaning scrub I do the steps above, and let them dry overnight so their water bottles for school are ready in time for the next day!
