Frequently Asked Questions

How do I clean my UltraFlask?

All of our SoftFlasks are top-shelf dishwasher safe so they are very simple to keep clean. If you are fueling with energy gels or mixing your own nutrition mix, we recommend using a bottle brush or Bottle Bright to clean out any residue. The bite valves and tubes can easily be removed for cleaning as well. Our Cleaning Kit provides you with both a tube brush and tablet of bottle bright to soak your valves in.
