How to open Atomiser Spray BottleUpdated 3 days ago
TL;DR: Hold the bottle firmly and twist the head anti-clockwise, pressing down on the top as you turn. If it is stuck, five to ten minutes in the freezer or sixty to ninety seconds under warm water usually frees the seal. Then fill to the line with Universal Cleaner and prime the pump.
How do I open Atomiser Spray Bottle?
✓ Step by step
Hold the bottle firmly and twist the trigger head anti-clockwise.
If it feels stiff, press down on the top as you twist to release the seal.
Fill to the line with Universal Cleaner. The line sits about 1 cm below the shoulder, exactly 300 mL.
Twist the head back on firmly, then prime the pump with two or three pulls.
What if the head is stuck?
⚠ Freeze method
Put the bottle in the freezer for five to ten minutes. The cold contracts the plastic and can loosen the head.
⚠ Warm water method
Run the head under warm, not hot, water for sixty to ninety seconds. The slight expansion frees a stubborn air seal.
✓ Still stuck?
If neither method works after a couple of attempts, get in touch with the Koh UK team rather than forcing it.
How do I fill it and get it spraying?
✓ Fill level
Fill to the marked line only. That leaves enough room in the bottle to prime and spray properly. Capacity is 300 mL.
✓ Prime it
Pump the trigger two or three times until the spray runs steadily. If the mist is weak, keep pumping to build the pressure.
⚠ Three drops of essential oil, no more
More than three drops of essential oil in Atomiser Spray Bottle can clog or damage the pump mechanism. Stick to three drops maximum and shake well after adding.
Essential oils do not naturally dissolve in a water-based cleaner, so mix thoroughly rather than adding more.
What if it will not spray once it is filled?
✓ Flush it through
Soak the head in warm water for a few minutes, reattach, and pump twelve or more times to flush the mist path.
Full instructions are in Atomiser Spray Bottle has stopped spraying.
✓ Prevent it
Rinse the pump with warm water every few refills and store the bottle upright in a dry place.
