How do I open Atomiser Spray Bottle?

Hold the bottle firmly in one hand and twist the trigger head anti-clockwise. If it feels stiff, press down on the top as you twist; that releases the seal. Once the head is off, fill the bottle to the line, which sits about 1 cm below the shoulder and holds exactly 300 mL. Twist the head back on firmly and prime the pump with two or three pulls.

✓ Step by step

Twist the head back on firmly, then prime the pump with two or three pulls.


What if the head is stuck?

Two methods work on a stuck Atomiser head. The freeze method: put the bottle in the freezer for five to ten minutes, as the cold contracts the plastic and helps loosen the head. The warm water method: run the head under warm, not hot, water for sixty to ninety seconds, as the slight expansion frees a stubborn air seal. If neither works after a couple of attempts, get in touch with the Koh UK team.

⚠ Freeze method

Put the bottle in the freezer for five to ten minutes. The cold contracts the plastic and can loosen the head.

5 to 10 min freezer

⚠ Warm water method

Run the head under warm, not hot, water for sixty to ninety seconds. The slight expansion frees a stubborn air seal.

60 to 90 sec warm water

✓ Still stuck?

If neither method works after a couple of attempts, get in touch with the Koh UK team rather than forcing it.

Do not force it

How do I fill it and get it spraying?

Fill to the marked line only, which leaves enough air in the bottle to prime and spray properly. The bottle holds 300 mL. Add up to three drops of Koh essential oil if you want a scent. Twist the head back on firmly and pump the trigger two or three times to prime. If the mist is weak, keep pumping until the pressure builds.

✓ Fill level

Fill to the marked line only. That leaves enough room in the bottle to prime and spray properly. Capacity is 300 mL.

300 mL Fill to the line

✓ 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.

2 to 3 pulls

⚠ 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.

3 drops maximum Shake after adding Koh oils only

What if it will not spray once it is filled?

Twist off the head, soak it in warm water for a few minutes, then reattach and pump the trigger twelve or more times to flush the mist path. Rinsing the pump with warm water every few refills prevents the build-up that causes it in the first place.

✓ 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.

✓ Prevent it
