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. If foam stops mid-use, hold the bottle upright. Foaming Spray Bottle is designed for upright use, and extreme tilting can interrupt the pump.
