How many loads in a 1.5L box?

A 1.5L box of Koh Sensitive Laundry Liquid provides approximately 60 regular washes or around 40 large loads. The exact number varies depending on machine size, soil level, water hardness, and personal preference. Dosing is 24ml (about 6 pumps with the Koh Laundry Pump) for a regular wash, or 40ml (about 10 pumps) for large or heavily soiled loads. The math is straightforward: 1500ml ÷ 24ml per regular wash = roughly 60 washes, or 1500ml ÷ 40ml per large load = roughly 40 large loads. For an average household washing 3 to 4 loads per week, a 1.5L box typically lasts 3 to 4 months.

✓ Load count

A 1.5L box gives around 60 regular washes or 40 large loads. For an average household, that's 3 to 4 months of washing. Actual count varies with machine size, soil level, and water hardness.

✓ How much per wash

For a regular wash, use 24ml (about 6 pumps with the Laundry Pump). For large or heavily soiled loads, use 40ml (about 10 pumps). Adjust based on load size and soil level. Less than this can leave clothes under-cleaned. More than this just wastes product without cleaning better.

How do I dose with the Laundry Dosing Cup?

Koh Laundry Dosing Cup is a heat-proof silicone measuring cup made for Sensitive Laundry Liquid. Dispense from the box into the cup (24ml for a regular wash, 40ml for large or heavily soiled), then pour into the detergent drawer or the drum. The cup goes in the dishwasher, and the silicone survives the dryer if it ends up in a load by accident.

✓ Manual measurement

Dispense from the box into Laundry Dosing Cup (24ml or 40ml mark), then pour into your machine's drawer or drum. The cup is heat-proof silicone: it goes in the dishwasher, and it survives the dryer if it ends up in a load by accident.


Can I use a pump instead?

Yes. The Koh Laundry Pump fits the 1.5L box of Sensitive Laundry Liquid and dispenses a measured 4ml dose per pump. Use 6 pumps for a regular wash (24ml) or 10 pumps for a large or heavily soiled load (40ml). The pump is the easiest option for households with a dedicated laundry setup because there's no box-tipping, no drips, and no measuring cup to wash. The Laundry Pump is sold separately or as part of the Sensitive Laundry Starter Kit.

✓ One-pump dosing
