Here’s a secret nobody tells you: your water bottle doesn’t die from age. It dies from your bad habits. You put it in your gym bag next to sweaty socks. You leave it in the car. You only rinse it with water after a week of neglect. Bacteria loves that.
A well-maintained bottle—washed with soap daily, dried upside down—can outlive its estimated lifespan. A neglected one becomes a science experiment in 3 months. I’ve seen mold that looked like a chia pet. Don’t be that person.
