How to open Foaming Spray Bottle

Fill to the 300 mL line with a Koh foaming formula, prime with two or three pulls, then choose a quick burst, wider spray, or continuous foam. →

How to use: Foaming Spray Bottle

The foaming head aerates the formula so it clings to vertical surfaces. A standard sprayer still dispenses it, but it runs off instead of staying put. →

Do I need the Foaming Spray Bottle? Could I use an alternative sprayer?

Bathroom & Shower Cleaner, Kitchen Grease & Oil Cleaner and Stain Remover. Other Koh formulas, like Universal Cleaner, are not designed to foam. →

Which products can I use with Foaming Spray Bottle?

Nine times out of ten it's the wrong refill. Check the bottle holds a foaming formula, then soak the head in warm water and pump through to clear it. →
