I have found a solution to get rid of that plastic taste in water bottles. It was in my moms "Better Homes and Gardens" magazine. It said to take 2 tablespoons of baking soda, and 2 cups of cheap vinegar. Now, just a quick warning, when you mix the two together, it will resemble a science fair volcano. Close it up, shake it, and pour out. Rinse it well with hot water, and you should get that taste out.

I bought a water bottle made by Arctic Zone from Totes, and it had a strong taste of plastic in the water. I used that method and now my water tastes like water. Couldn't have been more happy. Hope this works for all of you.
