How to open Foaming Spray BottleUpdated 16 days ago

TL;DR: Twist off the head, fill to the line with the right refill, prime the pump with 2-3 pulls, and spray. The Foaming Spray Bottle is built for Koh foaming products only.


Quick guide

1. Twist off the head

Turn anti-clockwise. Press down firmly as you twist if it feels tight.

2. Fill to the line

Fill to the shoulder line. That gives you the full 300 mL capacity.

3. Prime and spray

Pull the trigger 2-3 times, then spray using the foam modes.

How do I use Foaming Spray Bottle?

Open the Foaming Spray Bottle by twisting the head anti-clockwise. Fill it to the marked line with the compatible Koh foaming refill, then reattach the head and prime the pump with a few trigger pulls. Use half pulls for short bursts, full pulls for a longer spray, or hold and pump for continuous foam.

Fill rule

Do not overfill. Stay on the fill line for the best foam.

Prime it

Use 2-3 pumps to get the spray moving.

Foam modes

Half pull, full pull, or hold-and-pump for continuous foam.


What if the head is stuck or clogged?

If the head is stuck, try a short freezer chill or a warm water rinse. If the spray path is clogged, soak the head in warm water, then pump the trigger through the water to flush it clear. Reassemble and test again.

Freeze it

5-10 minutes in the freezer can help loosen a tight seal.

Warm it

Warm, not hot, water can free up a stubborn head.

Flush it through

Soak and pump to clear a blocked mist path.


What products can I use with it?

Foaming Spray Bottle is designed for Koh foaming products. For UK use, keep to the products listed on the compatibility guide and avoid off-brand fills that can affect foam quality or clog the pump.

Built for

UK-compatible examples
