Atomiser Spray Bottle has stopped sprayingUpdated 3 days ago
TL;DR: Twist off the head of your Atomiser Spray Bottle, soak it in warm water for a few minutes, then reattach and pump the trigger twelve or more times to flush the mist path. That clears most blockages straight away.
How do I get Atomiser Spray Bottle spraying again?
✓ The fix, step by step
Twist off the trigger head and check that the internal tube is still firmly attached.
Soak the head in warm water for a few minutes.
Submerge the head and pump the trigger quickly for about thirty seconds so warm water runs right through the mist path.
Reassemble, prime with two or three pulls, and test the spray.
Why did it block in the first place?
✓ Most common cause
A very fine mist runs through a narrow path, so residue collects. Essential oil residue in the nozzle is the usual culprit.
⚠ 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.
✓ Also worth checking
Universal Cleaner should be used undiluted. Diluting it, or filling the bottle with a thicker liquid, affects spray performance.
What if it sprays weakly, drips, or stops when tilted?
✓ Weak spray
The pump may not be primed. Pump the trigger several times to build pressure, and check the nozzle is turned to the on position.
✓ Leaks or drips
Turn the nozzle fully off when the bottle is not in use, store it upright, and avoid over-tightening the pump.
Check the bottle and trigger for cracks or damage.
✓ Stops when tilted
A weighted ball at the end of the internal tube lets the Atomiser spray at any angle. Shake the bottle gently so the ball moves freely and check the tube is securely attached inside.
What if it still will not spray?
✓ Try once more
Repeat the warm water soak and flush, checking the internal tube is seated correctly in the head before you reassemble.
