Can you put a coloured insulated water bottle in the dishwasher without fading?
Natural stainless steel Bambaw bottles are fully dishwasher proof, with no risk of fading.
For colour-coated bottles, hand-washing is recommended to help preserve the finish over time.
The bamboo lid should always be washed by hand with mild soap. Full care instructions are included in the digital guide with your purchase.
How to clean insulated water bottles properly?
For daily cleaning, wash your bottle with warm water, mild soap and a soft brush. Avoid scratching the inside.
Once a month, deep clean your thermal flask with hot water, vinegar and baking soda. Let it sit for 15 minutes before rinsing thoroughly.
You can also wash the bottle (lid removed) in the dishwasher, though hand-washing is more effective.
After cleaning, dry the bottle upside down and store it open. For complete instructions, refer to the digital guide included with your purchase.

No. The double-wall vacuum insulation keeps the outside dry. Your drink stays at the right temperature while your hands, desk and bag stay free from condensation.
How long do insulated bottles keep drinks hot or cold?
The insulated bottle keeps drinks:
- Hot for up to 12 hours
- Cold for up to 24 hours
Perfect for commuting, travel, workdays or outdoor activities.
Would a tea ball fit in the opening of this insulated water bottle?
Yes. The wide opening fits most tea infusers, tea balls, fruit infusers and ice cubes. It also makes the bottle easier to fill and clean.
What makes double-wall insulation effective?
A double-wall bottle contains two stainless steel walls with a vacuum between them. Without air movement, heat transfer slows down significantly. This helps keep drinks hot or cold for longer while preventing condensation outside the bottle.
