Can Chilly's Original Bottles rust?

Chilly's Bottles are made from high-grade stainless steel on both the inside and outside, so they should not rust provided they are cleaned and stored correctly. 

However, if liquids are left inside the bottle for longer than 24 hours this can eventually lead to rust developing.

We also recommend allowing your bottle to dry out fully after cleaning by storing it with the lid off when not in use. This just means that it won't stay damp on the inside for long periods of time, minimising the risk of the bottle rusting.
