Question:
Water Bottles?

Have I heard right that the bottles of water you buy from the shop are poisonous?By this I mean: you keep filling up this bottle at the gym with water and over a period of time the plastic bottle degrades with quality and subsequently becomes poisonous?True or is it false?

Answer: I make water bottles. Those clear water bottles are usually made from a type of plastic called PET. They do not break down over time. Where that might have some truth is the fact that most PET bottles cannot be washed in hot water without warping. So you might have a sanitation problem from not washing them properly. However, if you only use them for water, a mild detergent in warm water will probably do just nicely. If you use them for a sugar-based drink, that might be a bit more of a problem. Also, some of the new PETs are biodegradable. I don't know much about them yet. But I sincerely doubt the FDA would allow a toxic material for a food container.

The "heavier" reusable bottles made from HDPE (like the bicycle riders use) are usually washable in hot water, and should last as long as you like. Again, the plastic does not break down, it's just a sanitation issue.
