How long does Universal Cleaner last?

Koh Universal Cleaner 2L typically lasts around 3 months in a standard 2 to 3 bedroom home using the full Koh range. The 4L size stretches to roughly 6 months for the same household, at a lower cost per litre and with less packaging per use. Universal Cleaner is used neat in your atomiser or spray mop, so how long a box lasts comes down to how many surfaces you clean and how often, not to dilution rates. Unopened shelf life is 18 months. The formula is two ingredients, used undiluted, made in Australia.

Used neat, straight into your atomiser or spray mop. No mixing.

What affects how long Universal Cleaner lasts?

How long a box of Koh Universal Cleaner lasts depends on home size, cleaning frequency and how heavy the soil load is. Smaller homes, a weekly cleaning rhythm and the fine-mist Atomiser Spray Bottle stretch a 2L further. Larger homes, daily spot-cleans, mopping several rooms per session, and households with kids or pets run a 2L down faster. Universal Cleaner is used neat, so the variation comes from how much surface you cover and how often, not from how strongly you mix it.

✓ Stretches longer

Smaller homes. A weekly cleaning rhythm. Fewer surfaces per clean. Atomiser Spray Bottle fine-mist delivery puts down less product per spray.

Atomiser fine-mist Weekly routine Smaller home

⚠ Runs down faster

Larger homes. Kids or pets. Daily spot-cleans. Mopping several rooms per session. Heavier soil loads, so kitchens, post-renovation cleans and pet incidents, all take more product per square metre.

Should I get the 2L or 4L Universal Cleaner?

Choose Koh Universal Cleaner 2L if you have a small to medium household, are trying Koh for the first time, want the standard subscription frequency, or have limited storage under the sink. It lasts around 3 months in a typical home. Choose Universal Cleaner 4L if you have a larger home, are a heavy user or bulk-buyer, want the lowest cost per litre, or want to cut packaging, since one 4L box uses less packaging than two 2L boxes. It lasts around 6 months in the same home. Both are the same two-ingredient alkaline formula, made in Australia, with an 18-month unopened shelf life.
