When will I learn? I washed it in the dishwasher several times… I noticed that the seal wasn’t as tight. (The silicone seal in the cover actually stuck to the cup in my husband’s.) But I ran it through the dishwasher again (because it does a great job removing tea Stains — or so I told myself). THIS time, it melted and distorted the bottles. I am sick over this. The Drinking spout was the part I loved. Most.
I looked through the instructions and honestly did not see dishwasher warnings. And I thought ‘Oh, Titanium must be a stronger plastic that can handle the dishwasher.” WRONG!
Here’s the lesson: If it has plastic or silicone, DO NOT PUT IT IN THE DISHWASHER!!! End of story.
