How do I fix a blocked Atomiser Spray Bottle?Updated 4 hours ago
TL;DR: On very rare occasions Atomiser Spray Bottle can become blocked due to the super fine mist sprayer. Remove Atomiser Trigger Head and straw, flush under warm water by pulling the trigger, reassemble, and it should work again.

How do I fix it?
✓ Flush it clear
Take Atomiser Trigger Head off the bottle, keeping the tube attached to the head.
Submerge the tube end under warm water and pull the trigger quickly to flush the system. Keep pumping for about 30 seconds.
Shake off excess water, twist the head back onto the bottle, and prime with 2 to 3 trigger pulls. Atomiser Spray Bottle should now work as normal.
Why does it happen?
✓ Fine mist build-up
Atomiser Spray Bottle uses a super fine mist nozzle for even coverage. On rare occasions, dried residue or tiny particles can build up and block the mechanism. Flushing with warm water clears it out and restores normal flow.
⚠ Still blocked?
If flushing doesn't fix it, Atomiser Trigger Head is available as a replacement part. Swap it out and your bottle is good as new.
