What makes Universal Cleaner a safer choice for people with asthma?

Koh Universal Cleaner is approved under the Sensitive Choice program, run independently by the National Asthma Council of Australia, which assesses products as better options for people with asthma. The formula is two ingredients: potassium hydroxide and laboratory grade purified water. There is no added fragrance, no chlorine, no bleach, no ammonia and no added solvents, which are the airborne triggers most often linked to asthma symptoms in conventional cleaning products. Triggers vary from person to person, so patch-test first if you have a known reactive condition.

✓ Sensitive Choice approved

Independently assessed by the National Asthma Council of Australia as a better option for people with asthma. No added fragrance, which is the trigger most often named in conventional cleaning products. No chlorine, no bleach, no ammonia, no added solvents.

Two ingredients only: potassium hydroxide and laboratory grade purified water. It's a higher alkaline solution, so it works by lifting soils rather than by masking them with perfume.

What makes Universal Cleaner a safer choice for allergies and eczema?

Koh Universal Cleaner is certified by Allergy UK, the UK's leading allergy charity, and recognised by the Eczema Association of Australasia as suitable for eczema-prone households. The two-ingredient formula is made without the additives most often linked to reactions in cleaning products: synthetic fragrances, preservatives such as parabens and methylisothiazolinone, dyes, and irritant surfactants. Sensitivities vary from person to person. If you have a known reactive condition such as contact dermatitis, patch-test a small area before wider use.

How do I know it will suit my own triggers?

Asthma and allergy triggers are personal, and two people with the same diagnosis can react to completely different things. That is why Sensitive Choice, Allergy UK and the Eczema Association of Australasia assess a formula against defined criteria rather than issuing a verdict for every household. Those assessments tell you Koh Universal Cleaner cleared independent thresholds set by bodies that specialise in asthma, allergy and eczema. Your own triggers are the part only you can test: patch-test a small area, clean with a window open the first time, and talk to your doctor or specialist about your own history.

✓ Triggers are personal, so start small

Asthma and allergy triggers vary from one person to the next. Two people with the same diagnosis can react to completely different things, which is why Sensitive Choice, Allergy UK and the Eczema Association of Australasia assess a formula against defined criteria rather than issuing a verdict for every household.

What those assessments give you is an independent read on the formula from bodies that specialise in asthma, allergy and eczema. Your own triggers are the part only you can test. Patch-test a small area, clean with a window open the first time, and talk to your doctor or specialist about your own history.

How can I reduce trigger exposure while cleaning?

A few routines cut exposure further for anyone managing asthma, allergies or eczema. Ventilate the room by opening a window or door. Spray onto the cloth rather than misting the surface, which reduces airborne mist in small or enclosed rooms. Pair Koh Universal Cleaner with Koh Universal Cloths, which trap dust, pollen and dander rather than flicking them into the air. Wear gloves if you have contact dermatitis, and keep a window open or a fan on for 10 to 15 minutes after you finish.

✓ Three-step low-trigger clean

1

Ventilate. Open a window or door before you start, and leave it open for 10 to 15 minutes after you finish.

2

Spray the cloth, not the room. In small or enclosed spaces, spraying onto the cloth instead of misting the surface cuts airborne mist.

3

Use a Koh cloth. Universal Cloths trap dust, pollen and dander rather than flicking them into the air. Pair Universal Cleaner with Universal Cloths and wear gloves if you have contact dermatitis.
