No. I believe it will not rust.

No it is high quality stainless steel.

Nope. And I’ve had it for several months and use it every single day. Although I do admit I clean it and dry it everyday.

I’ve been using mine nonstop for a few months now and mine hasn’t rusted. It’s actually still looking brand new.

No! Definitely not. Unlike other bottles, we use true solid stainless steel grade material. Most bottles do not use true stainless steel which is why you see some rust. Knives can do this too. And if it does, Just get in touch with us!
