I've got 4 of these since shortly after they came out which is well over a year. None of them have a mold growing problem.ettore said:I got one from a friend, doesn't seem to grow mold (and my GF has a biology doctorate, she is the biggest germophobe/moldophobe that exists). I don't do anything special, and I only put water in it. In fact, I am actually pretty bad at leaving water in it for weeks; no mold.
Mine grew mold in a month or so, too. Only used water in it.5b00 said:I've had this bottle for a few weeks and the spout has been growing mold, even if I clean it religiously with dishwashing soap after using it. Immersing in boiling water or vinegar doesn't help. You can really get rid of the mold by taking it apart, but it's a real hassle to disassemble the spout.
Few online reviews have pointed out this flaw, but maybe I've just had bad luck with mold. It smells the same as the the stuff that grows in high-efficiency (front-loading) clothes washers. Sorry to crap on the thread, though it is a good deal if you don't get mold.
Since so many people have ones that don't grow mold it's probably a materials problem. I'm in humid Michigan btw, not a 10% humidity South Western desert area.shiggy said:Mine grew mold in a month or so, too. Only used water in it.
Bought it on a lark, and tossed it just as quick. I have dozens of Specialized Big Mouth bottles, which remain the best bottle available, overall. Have not needed to buy any of them, either.tl1 said:Since so many people have ones that don't grow mold it's probably a materials problem.
