Firstly, is to fill half the bottle with soapy water, shake it and let it rest for a while before rinsing it with clean water.

Morevoer, we also have a brush designed specifically to wash the bottle thoroughly especially the handle part and the edges of the bottle 😇. The brush is available to purchase on our website.

If you're looking for a bottle with a larger cap for easier cleaning, check out our new OVERSIZED Pro. It features a wider cap that allows you to fit your hand inside for thorough washing.
