BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles, and baby bottles.. A lot of us are using BPA free products now including water bottles.
Sometimes it can be difficult to clean the bottles because of their narrow necks. Here are a few tips that have helped me.. Some containers are dishwasher safe placing them on the top rack and putting the lid in the silver are basket is great. But for those that are hand wash only.. Fill half way with hot water and a squirt of dish washing liquid attach the lid and shake, pour the suds water out as you rotate the bottle in your hand ( so it washes over the entire lip of the bottle, Rinse well and let dry.
To eliminate the smells that can occasional occur. Add one teaspoon of baking soda and 1/2 teaspoon of bleach to the bottle, Fill half way with hot water and swirl it around to mix then add more hot water to fill the bottle.Clean the lid with a clean toothbrush dipped in baking soda, rinse and let dry. Let the filled bottle sit overnight. Then rise well with hot water, wash rinse and let dry.. Store bottles with lids off to help to keep odors from being trapped.
* consider buying a baby bottle brush to clean the bottle with.
