Frequently Asked Questions about KeepCup Water Bottles

How do I clean my KeepCup insulated water bottle?

Cleaning your stainless steel water bottle has never been easier! Thanks to the dual-opening design, simply unscrew it in the middle and place it in the dishwasher. No bottle brush needed! 

We can't promise the bottle won't need a scrub, but if you regularly clean the water bottle parts separately in the dishwasher, it's unlikely. For best results remove the gaskets from time to time.

A note of caution if you like your steel water bottle pristine, we recommend handwashing it to preserve the surface finish. The water bottle lid can be disassembled into four parts for longevity and easy cleaning. For full drink bottle cleaning instructions, visit our care page.

Can I put hot liquids in my KeepCup drink bottle?

Absolutely. KeepCup’s water bottles are designed to keep your beverages hot or cold. The vacuum-insulated stainless steel construction of our bottles ensures that they can handle hot liquids, keeping your drinks warm for hours. However, do not store carbonated beverages in your steel water bottle.

Is the drink bottle insulated?

The base Travel Mug part of the drink bottle is vacuum-insulated. The water bottle lid is clear single-wall premium clear plastic or double-wall stainless steel. Vacuum sealing provides increased thermal insulation when compared to double-wall construction, as it removes the air between the walls, creating a vacuum that slows down temperature transfer. Because our waterbottle lid is open-ended, it cannot be vacuum-sealed.

Why does the drink bottle split in the middle?

The dual-opening water bottle solves a few problems. The wide mouth of the water bottle allows you to fit your ice, fruit and other treats. The main advantage is that your bottle can be easily and thoroughly cleaned in the dishwasher - no need for a water bottle brush. Of course, the bottle also converts from a bottle to a Travel Mug which is super when you want to travel light on the move!

Are the drink bottles BPA free?

All KeepCup products are BPA and BPS-free. Most of our plastic parts are made in Australia and the United Kingdom. The bottles comply with global food safety health regulations and contain no BPA, BPS, phthalates, DEHP, lead, or cadmium.
