How long should we change a new thermal bottle? Should we put coffee or tea into the bottle?

Generally, if you use the bottle properly and maintain it well, it can be used as long as it still functions well (i.e. keep warm and cold). Here are some maintanence tips.

1. Coffee, tea and fruit juices can be put into the thermal bottles. However, we recommend you to finish them in 2 to 3 hours. The bottles should be cleaned right after to avoid odors and stains remaining. (TIPS: TIGER’s Super Clean technology can make cleaning easier)
2. Avoid soft drinks, uncooked milk, chinese medicine and alchoholic drinks.
3. Clean by a sponge, avoid using brush and washing machine
4. Protect the vacuum layer
