Q. Gear Guy, How do I prevent the nasty odor and taste that I get when I store my Nalgene bottle with the lid closed?

A. A stinky, sour water bottle is no fun. I’ve had that problem myself. There are a couple of things you can try. First, soak the bottle in warm, soapy water. If it’s particularly nasty, add some lemon juice or a couple of tablespoons of baking soda to the water. Let the bottle soak overnight, then run it through the dishwasher (on the top rack only). Dry the bottle upside down with the top open. If all that doesn’t work, it’s time for drastic action. Nalgene’s Web site suggests this: Take a charcoal briquette, roll it up inside a piece of newspaper and shove it inside the bottle, then screw on the cap. Leave it in there for a few days. Finish by washing the bottle in the dishwasher or by hand in warm soapy water.
