Reusable water bottles are great for the planet, but daily use can lead to build-up from drinks, saliva and organic residues. A Koh clean breaks down grime, eliminates odours and keeps your bottle hygienic and fresh.
What you need
✔ Universal Cleaner
✔ Dish Brush
✔ Atomiser Spray Bottle
✔ Universal Cloth
✔ Kettle
Step-by-step guide
Step 1
Spray Universal Cleaner liberally inside and outside the bottle, including the lid and threads.
Step 2
Leave for five minutes to allow the cleaner to break down organic residues.
Step 3
Scrub the inside of the bottle and lid with a Dish Brush or similar.
Step 4
Rinse thoroughly with cold running water.
Step 5
For sterilisation, fill the bottle with boiling water from the kettle and place the lid in a cup filled with boiling water.
Step 6
Leave both for ten minutes before carefully emptying.
Step 7
Rinse again under cold water and dry as normal.
Pro tip
For bottles used daily, aim for a deep clean once a week — it keeps your drink tasting fresh and prevents odour build-up.
