Dosing liquid laundry detergent correctly can be tricky, but getting it right saves money, protects your washing machine, and minimizes environmental impact. As laundry experts with years of testing detergents and machines, we'll guide you through precise measurements based on load size, water hardness, and soil level.
Standing in front of your washer, you've likely wondered: "How much detergent is enough?" Too much wastes money and harms fabrics; too little leaves clothes dingy. Here's the solution.
The right detergent dose:

1. Use 50 ml for a 4-5 kg load.
2. Use 75 ml for a 6-8 kg load.
3. Use 100 ml for a 9 kg load.
These are starting points for soft water and lightly soiled laundry. Adjust based on the detailed table below:

For example, a heavily soiled 4-5 kg load in hard water needs up to 150 ml. Let's break down the key factors.

Soil level is the first consideration. Dirtier loads require more detergent:
Sort laundry by soil level for optimal dosing. Pre-treat tough stains for best results—see our stain removal guide.
Pro tip: Learn how often to wash clothes to reduce loads.
Water hardness measures calcium and magnesium levels, impacting detergent efficiency. Harder water needs more product:
Check your water bill, contact your supplier, or use test strips/kits for accuracy.
Match detergent to your washer's capacity and fill level—more laundry means more detergent. Consult your machine's manual (e.g., Whirlpool, Miele) for rated capacity. Aim for full but not overloaded loads for efficiency. Learn how to check if your machine is overfilled.

Overdosing doesn't clean better—it causes issues:
Detergent labels often overestimate to boost sales. Trust these proven guidelines instead.

Lost the cap? Use a dosing ball, measuring cup (dual-purpose for cooking), or mustard jar: small (100 ml), standard (200 ml).
