How many times is it safe to reuse a plastic water bottle?

Answer 1

eeew...did you see that news story on that? According to the findings, it's never safe to refill them!

They even tested ones that people took to the gym and then put in the dishwasher, and it was still growing stuff like e coli and other bacteria because they can't be cleaned properly because of the shape.

Answer 3

The answer is yes, but not for very long.

Most of these disposable bottles are made from a flexible plastic, called polyethylene. Some people worry that repeated washings could release potentially harmful chemicals from the plastic.
But according to the UC Berkeley Wellness Letter, the studies on this "have had inconsistent results and researchers disagree about whether these compounds pose a significant risk."
Here's a better reason to recycle that bottle after a few uses. Re-use a disposable water bottle over and over again and you run the risk of bacterial contamination.
"Ya know you drink out of it, so your mouth is on the bottle and all the bacteria in your mouth get into the bottle,” says the Wellness Letter’s Dr. John Swartzberg. “And then you refill the bottle and if you haven't cleaned it well, then those bacteria could have multiplied in the meantime, because there's still some moisture left in that bottle."
If you want to re-use that bottle - a few times - wash it with hot soapy water in-between fillings. Don't forget to wash the cap and inside of that narrow neck. Never try to wash it in the dishwasher; the plastic is not designed to handle the high heat.
Keep a re-filled bottle in a cool place and out of the sunlight. The Wellness Letter says sun and heat can speed up bacteria growth.

Bacterial Concerns for All Water Bottles: The real culprits for the safety of reusing any water bottle are the bacteria and fungi that can grow in damp or partially full bottles once they have been opened. These bacteria generally come from your hands and mouth, or any dirt that comes in contact with the mouth of the bottle.

Cleaning Your Water Bottle: Both single-use and reusable water bottles should be thoroughly cleaned and dried between uses. Reusable water bottles generally have wider mouths, making them easier to clean. Dishwashing soap and hot water are acceptable to use for cleaning your water bottle. The risks of bacterial and fungal growth are higher if you use the bottle with a drink that contains sugars. Immediately drain, rinse, and wash your water bottle after your walk if you use it with sports drinks or juices.

Sanitizing Your Water Bottle: If you have visible bacterial slime or mold in your water bottle, you should sanitize your water bottle with a dilute bleach solution of 1 teaspoon bleach and 1 teaspoon of baking soda in 1 quart of water. Allow the solution to sit in the bottle overnight, then thoroughly rinse and dry the bottle before using it again.
