Note about Klean Kanteen's wide mouth bottle lidI bought a Klean Kanteen wide mouth for my daughter and she used it today. She tasted a metallic taste, then found a green substance around the rim.
I found two reviews at Amazon.com stating the same thing. One guy contacted Klean Kanteen and he says they're having him send the bottle in for an exchange and so they could look it over. They thought perhaps the green stuff was residue from the polishing process that got under the rim.
Again, this refers to their new wide-mouth bottle, or the lid anyway.
After I washed dd's bottle and lid, the bottle smells fine, not metallic at all.
I haven't contacted KK yet, but will be in the morning.
By the way, I otherwise recommend the Klean Kanteen. We had no problem with our 2 original KK bottles.
