Hi Serene--- Some cloudiness or white spots can at times be caused by the hard water used to clean the tubing. These are a result of the mineral deposits in the water and are not toxic. You would still be able to use the tubing, but you may just have a more difficult time seeing through the tubing to ensure cleanliness. The tubing does not need to be sanitized. It should only be washed if dirty or if milk is present. If you have any other questions, please consider live chatting with us on our website. We're here to help!
