Universal name, universal by nature. Our Universal Cleaner can be used on just about every surface in your home. Including all the ones you expect like the kitchen, bathroom and hard surfaces and a few you might not, like fabrics, windows and organic odours. To get the best out of your Koh Universal Cleaner pair it with our Atomiser, Spray Mop, Cloths, Diamond Sponge and Grout Brush.
is a big pack better for my budget?
Sure is! Our 4L Universal Cleaner lasts for months of hardcore everyday use and works out at less than $1.50 per week. Because our Universal Cleaner has over 20 applications you can use it across your whole home and make a sweep on your cleaning budget, too. Plus, bigger packs mean less waste, so there are a lot of wins.
what's it made from?
Our Universal Cleaner is a two-ingredient powerhouse. Made from koh (or potassium hydroxide to all of us who drifted off in chemistry class), purified water and that’s it. No bleach, ammonia or hardcore nasties. Just an incredibly effective, Australian-made, GECA and Sensitive Choice-certified Canstar Blue winner. We like to think of it as everything you need and nothing you don’t. For safety warnings, please refer to the product packaging. If ingested or in case of an emergency, contact the Poison Control Center at 1-800-222-1222.

Australia's #1 multipurpose cleaner
Our Universal Cleaner is the star in the Koh line-up for good reason. It replaces armfuls of other cleaning products, doesn’t contain a list of dodgy ingredients, and is powerfully effective whether you’re sweeping up spills, wiping windows or tackling the toilet. We’re also the first brand to be awarded Canstar Blue’s #1 Multipurpose Cleaner two years running. Win!
We want you to buy less
We know that seems a bit weird for a cleaning company. Shouldn’t we be spruiking specialist cleaners for every type of stain and spill with loads of extra ingredients for that little extra something? Instead, our Universal Cleaner can be used on basically everything, has two eco-certified ingredients, and comes in a bulk package so it lasts for months. That’s it, no nasties, family-friendly ingredients and epic results without loads of elbow grease.

FAQs
What makes Koh eco-friendly?
We believe a clean home shouldn’t come at the cost of the environment around us. That’s why Koh's cleaning products are packaged to minimise as much waste as possible and use tools that are reusable, refillable and very long-lasting. What’s on the inside counts too, Koh cleaning products are certified by GECA, Australia’s only independent, not-for-profit sustainability and environmental certification as a good environmental choice.
What sets Koh apart from other brands?
Koh fights dirty by delivering a simple, safe, sustainable, and super effective cleaning solution that rejects cleaning as a chore; instead empowering users to seek the joy of a clean, green home. Read on for more about our simple, safe, sustainable, super effective (and smart) philosophy:
Simple
If you’ve ever peeked under a few sinks, or perused your local cleaning aisle, you might come away feeling that cleaning is…complicated. We say it’s time for a clean sweep, and call a mop a mop. From our Universal Cleaner to our Sensitive Laundry Liquid, we bring calm to a noisy category with straightforward products that say what they do and are designed to work together.
Safe
From baby’s feet to your dog’s nose, the surfaces of your home are in constant contact with you and your family. Our products are independently supported by The National Asthma Council Australia’s Sensitive Choice program, and Allergy UK to be a better choice for asthma and allergy sufferers. Our GECA accreditation also certifies that our cleaning solutions don’t contain harmful ingredients that can cause adverse health effects.
Sustainable
We believe a clean home shouldn’t come at the cost of the environment around us. That’s why Koh's cleaning products are packaged to minimise as much waste as possible and use tools that are reusable, refillable and very long-lasting. What’s on the inside counts too, Koh cleaning products are certified by GECA, Australia’s only independent, not-for-profit sustainability and environmental certification as a good environmental choice.
Super effective
Like it or not, ‘green’ products don’t always have the best reputation. Organic ingredients are friendly on the skin, but sometimes a little too friendly on grime. Koh ticks both boxes: our formulas tackle mess instantly, without stripping your skin or making you wheeze. Bathroom, kitchen, or crayon on the wall; Koh cleans it all — fast.
Smart
The cleaning industry has long leaned on hardcore chemicals delivered with plenty of elbow grease. At Koh, we believe in less leaning, and more cleaning. That’s why we’ve doubled down on innovation, to develop our own (scientifically tested) products, delivered with tools that make your clean a dream. From atomisers that use less, to loo blades that swipe more, we’ll never stop working hard to make your clean easy.
Are Koh products safe to use around pets?
Our cleaning system is designed to be family and fur-baby friendly, with no nasty chemicals, fumes or fragrances.
Our solutions are proudly part of the Asthma Council Australia's Sensitive Choice program. Products that carry the Sensitive Choice blue butterfly have been reviewed and approved by an independent expert panel that determines their potential benefit to people with asthma and allergies.
Whilst our products are the safer choice we do recommend using with caution around your pets.
Do any products have fragrances?
Koh products are proudly fragrance free and independently verified by The National Asthma Council Australia’s Sensitive Choice program and Allergy UK to be suitable for those suffering asthma and allergies.
Smelling “clean” doesn’t necessarily mean you’ve got an effective clean - fragrances often mask toxic chemicals lurking beneath. Even worse, manufacturers use fragrances to cover up undisclosed ingredients.
Here’s why we choose to go fragrance free:
- Health Risks:Fragrances trigger conditions such as allergies, and asthma and sometimes more serious illness.
- Undisclosed Ingredients:Manufacturers hide over 100 toxic components under the generic label 'fragrance.'
- Misleading Terms:'Unscented' doesn't guarantee fragrance-free, and 'Fragrance-free' may still contain original formula scents. Be a label detective.
- Natural Fallacy:'Natural' is often a greenwashing tactic; it's no guarantee of safety, as natural fragrances can be as toxic as synthetic ones.
