✓ Need a replacement head?
Foamer Trigger Head is available separately. Swap it out and your bottle is good as new.
How do I set it up?
✓ Steps 1 and 2
Twist off Foamer Trigger Head by turning anti-clockwise. If it's stiff, press down firmly on top as you twist.
Fill to the line from your refill pouch. The fill line sits about 1 cm below the shoulder, exactly 300 mL capacity.
✓ Step 3 — prime and foam
Prime the pump by pulling the trigger vigorously 2 to 3 times. Then half-pull for a quick burst, full pull for a longer spray, or hold and pump for continuous foam (it'll keep foaming for about 1 to 2 seconds after your last pull).
What if the head is stuck?
⚠ Freeze method
Pop Foamer Trigger Head in the freezer for 5 to 10 minutes. The cold contracts the plastic and can help loosen the seal.
⚠ Warm water method
Run the head under warm (not hot) water for 60 to 90 seconds. The slight expansion can free up any stubborn air-seal that's formed.
What if it clogs?
⚠ Clear the blockage
Twist off Foamer Trigger Head and soak it in warm water for a minute, then pump the trigger 12 or more times to flush it through.
What refills can I use with it?
Need a spare?
Foamer Trigger Head is sold separately. Swap it out if yours ever gets worn or damaged — no need to replace the whole bottle.
