From the complaints department - sent over a month ago and no reply. Emailed the eBay vendor today... maybe they'll respond somehow:
----- Original Message -----Sent: Monday, July 07, 2008 11:04 AMSubject: Stainless Loop Cap - waterloggedI received my first 18oz Klean Kanteen very excitedly last week. I specifically ordered and paid extra for a stainless steel lid (loop cap) because I wanted to avoid any plastic parts in contact with my water. However, the very first time I washed the lid (by hand), the inside of the cap filled with water and now makes a sloshing sound. It seems impossible to open and clean inside - meaning whatever dishwater is trapped in there is going to eventually fester and grow algae, mold, etc. I am extremely disturbed that something like this would happen to a product known for its cleanliness (or, perhaps, "kleanliness", which may be something different) and non-toxic durability.I understand that this is the reason you recommend against dishwasher use with the caps. However, since we don't even have a dishwasher, the cap was only washed by hand along with the bottle and immersed for just a short time.I'm not using the bottle now, and I'm wondering whether the PP#5 lid is a one-piece design, and if so, whether it might be possible to exchange one for this useless, water-logged stainless steel lid. :-(I'd appreciate any help you can offer.
