Which products can I use with Foaming Spray Bottle?Updated 3 days ago
TL;DR: Three Koh formulas: Bathroom & Shower Cleaner, Kitchen Grease & Oil Cleaner and Stain Remover. Anything else will spray, but it will not foam properly and may dribble, jet or clog the nozzle.
Which Koh products work with Foaming Spray Bottle?
Foams up for better contact on tiles, grout and glass, and lets the formula sit on vertical surfaces instead of running off.
✓ Kitchen Grease & Oil Cleaner
Foam clings to vertical surfaces like extractor hoods and splashbacks while it lifts grease.
Pre-treat or spray directly onto fabric. The foam helps the formula sit where you need it before washing.
What should I avoid putting in it?
⚠ Not compatible
Do not fill Foaming Spray Bottle with Universal Cleaner, Dishwashing Liquid or Sensitive Laundry Liquid. These formulas are not designed to foam and can cause a weak spray, clogs, or no output at all.
The foaming mechanism is tuned to specific formula viscosities, which is why only the approved Koh products work properly.
✓ Where these belong instead
Universal Cleaner goes in Atomiser Spray Bottle. Dishwashing Liquid pairs with Dish Pump. Sensitive Laundry Liquid pairs with Laundry Pump.
The full pairing list is in What tool do I use with what product?.
✓ What goes wrong
A non-foaming formula in the foamer typically dribbles, jets in a thin stream, or produces nothing at all. It can also leave residue in the nozzle.
Can I add essential oil to the foamer?
⚠ Three drops maximum
More than three drops of essential oil can clog or damage the pump mechanism. Mix well after adding, as oils do not dissolve naturally in a water-based cleaner.
✓ Which oil
Eucalyptus Oil is the one made for bathroom surfaces, and pairs with Bathroom & Shower Cleaner.
Lemon Scented Tea Tree Oil is currently out of stock in the UK.
I already filled it with the wrong product. What now?
✓ Putting it right
Empty the bottle and rinse it out with warm water.
Twist off the head and soak it in warm water for a few minutes.
Pump clean water through the nozzle twelve or more times to flush the path.
Refill with a compatible formula, prime with two or three pulls, and test.

Just the bottle
Pair Foaming Spray Bottle with any compatible Koh foaming formula for even, clinging coverage.
