Flask
Fill with warm water, add a tablet and leave it open for 15–30 minutes. Old coffee stains? Leave it longer or repeat.
How it works
Three steps, zero scrubbing. Here's everything you need to know.
01
Warm water in
Nearly to the top. Warm, not boiling.
02
Drop & fizz
Leave the lid off while it fizzes.
03
Wait 15–30 min, rinse
Rinse every part well. Don't drink the solution.
How many tablets?
| Bottle size | Tablets |
|---|---|
| up to 500 ml | 1 tablet |
| 500 ml–1 l | 2 tablets |
| over 1 l | 3 tablets |
Lid & seals
Pop out the seal and valve if you can. Soak every part in a cup of the solution, then run the seal brush along the grooves.
Straw
Soak the straw in the solution or leave it in the bottle while it cleans. Then push the straw brush through.
Kids’ bottles
Take every part apart, soak for 15 minutes and rinse very well with clean water. Air-dry.
Shaker
Protein residue gets smelly fast. Rinse after the gym, and fizz it once a week — mesh included.
