Keeping My Family’s Reusable Water Bottles Clean and Yucky Free

I’m on a quest to be as eco-friendly as possible and as I discussed last week, keeping my family hydrated is always top of mind. So, it’s a given that refillable water bottles are a part of our everyday lives. However, as awesome as our reusable bottles are, it’s no secret that they’re also a perfect breeding ground for bacteria. As I work hard to keep my family as well nourished as possible, I’ve become aware of not only the healthful foods I’m intintionally giving them but also the unintentional yucky “germs” that sneak in when I take certain shortcuts….like just giving bottles a quick rinse. Thus, part of my routine involves keeping our stash of refillable bottles in spit spot shape. In this week’s blog post I’m sharing a small bit about what causes bacteria and details on my method to prevent it.

First, a quick blurb about what causes bacteria in water bottles.  According to Wikipedia, ( reusing bottles could develop bacteria in the bottle between uses. Mouth contact to the bottle openings can easily transfer bacteria to the water content which can subsequently contaminate both bottle and water. Contamination will cause bacterial and fungal growth in the water while kept in storage; if the user cleans the bottle very well before reuse, the risk is much less.

So how can you keep your water bottles clean and free of contamination? Here’s what I do:

1.) I have a designated water-only bottle for each member of my family. Occasionally I offer other beverages to take on-the-go, such as milk, but I always use a different canteen for this (the old water bottles become designated for other beverages). There are mixed thoughts on plastic bottles and leaching so to be on the safe side I always go with stainless steel or glass and prefer ones with a flip-up or pop-up spout rather than a threaded mouthpiece.

2.) I wash each bottle at the end of the day with a bottle brush and warm, soapy water. A bottle brush works wonders at getting out anything that might be “growing” on the sides. If your bottle has a straw, use a straw brush to quickly get inside (especially the portion that touches your mouth). For bottle and straw brushes, you don’t need anything fancy and you should replace them about as often as a sponge so I go for whatever has the best price point (Amazon and Target both have plenty of options). Some people put their bottles in the dishwasher but I prefer the old fashioned way and always hand wash my bottles, I find it preserves any decals that are on the stainless steel bottles and gets the bottles just as clean (especially if very hot water is used). On a separate note, it’s also important to keep the bottle brushes clean and bacteria-free and for this I put the brushes in the dishwasher at least once each week.

3.) After washing the bottles, I leave them (and their parts) in a place where they can get plenty of air to dry overnight — don’t ever put the top back on a damp water bottle and put it in the cabinet for future use. This is the ultimate invitation to bacteria! For drying, I use the Boon Grass Countertop Bottle Drying Rack (, it keeps bottles raised and sanitary and provides great circulation for faster drying  OXO also makes a great drying rack (

4.) Approximately once per week I give the bottles a deeper clean. I put around one tablespoon of baking soda in the bottle, fill it with hot water and cup my hand over the top to give it a quick shake. Meanwhile, I put another few tablespoons in a glass bowl, fill it with hot water and add all the bottle components for their own “bath” (lids, straws etc). After a few hours of soaking time, I rinse the bottles and parts thouroughly, being careful to get rid of any baking soda residue.  White Vinegar also works well for a deeper clean and when I’m mistakingly out of baking soda this is my go to. With vinegar, I add around a 1/4 cup, fill the rest of the way with water and let the bottles stand this way overnight.

5.) And, finally my favorite step! After my bottles are clean and dry, I love to add a few drops of food-grade lemon or orange essential oil to the bottom before filling with water. Essential oils are known for their antibacterial properties and by just adding a few drops of a citrus oil, I get a nice refreshing hint of taste along with some great aromatherapy all day!

Please come back and visit next week, I’ll be writing about the water bottle refilling stations that are popping up EVERYWHERE (at least all over San Francisco).




Keeping My Kids Hydrated with Water-Packed Foods

My older daughter Cypress had to be taken to the emergency room last year with severe neck pain and a host of other symptoms. She was just over 5 at the time. Luckily, it turned out to be just a scare and basically “nothing”, however the doctor told me that her symptoms could have been caused in part by dehydration. I was shocked by this……I thought to myself “I’m a good mom”, I send her to school everyday with a full water bottle, I always have water with me, how could this be? But as my initial defensiveness subsided and I began to review the previous few weeks in my head, I realized there were many days that the water bottle I packed for school came back home full and that although I offered water throughout the day there really was no guarantee that she was drinking enough. So, I did what any parent would do and began monitoring her water intake much more closely and really tried to encourage her to drink more, explaining in layman’s terms why water is so important for our bodies. Her water intake definitely improved but I was still feeling like she wasn’t drinking enough.

I decided that I needed to get more creative and tried a range of things. I don’t generally allow juice, however I found if I put a small splash of some sort of organic juice (apple, blueberry, grape) in her water, she did tend to drink more. I also discovered that she liked tea and in the morning and evening began making various teas like hibiscus, berry and mint, sweetened with just a tiny drop of stevia. However, one of my favorite ways that I began to “sneak” water into her was by packing a lunch full of hydrating foods. Hydrating through foods has been a change that has stuck for our entire family, becoming a healthy habit that I no longer need to try to remember to do.

Her lunch today included half of a turkey sandwich, along with a side of fruits and veggies that all toll added up to more than 1 cup of water!

I fill the lunchbox with as many hydrating foods as possible

It’s a fact, eating foods, such as cucumbers or strawberries, contribute to your overall fluid intake and help you stay hydrated. And, there are so many water-packed foods that I can constantly rotate to keep lunch interesting. What’s more, her lunches are filled with a lot more nutrition. There’s Vitamin C in everything pictured, not to mention the lycopene in watermelon and peppers, fiber in cucumbers, thiamine, vitamin B6, beta carotene and folic acid in red pepper and my favorite….celery, which contains the highest percent of water along with the longest list of nutrients, including vitamins B1, B2, B6 and C potassium, folate, calcium, magnesium, iron, phosphorus, sodium and plenty essential amino acids.

And, if extra hydration and nutrition isn’t enough to convince you, adults may be interested to learn that research shows that eating foods that are full of water will also help keep you satisfied on fewer calories.

Here’s a table of some of my lunchbox favorites, including water content percent and some of the added nutritional benefits of each food:

And for those of you that need even more evidence in order to start integrating hydrating foods into your diet, I will leave you with this……A 2009 study at the University of Aberdeen Medical School found that the combination of salts, minerals and natural sugars in some fruits and vegetables can actually hydrate people more effectively than water or even sports drinks. Watermelon was on top of the list, thanks to its 92 percent water content and essential rehydration salts calcium, magnesium, potassium and sodium.
