What detergent costs per wash

Sep 20, 2026

Short answer: A dose costs between one and two kroner, and most people use twice as much as they need. Halve the dose and you halve the cost without your clothes getting any less clean, while sparing them from soap residue.

The dose on the pack assumes the worst

The recommendation is for heavily soiled clothes in hard water, which is rarely the case. Most everyday clothing has been worn for a day and is only lightly soiled. Read the dosing table on the pack and pick the lowest line. For lightly worn clothes like the women's range, half is enough, often less.

Too much detergent costs twice

Beyond the price itself, overdosing leaves soap residue that needs an extra rinse. It can settle in the fabric, making it stiff and leaving a faint smell over time. The machine uses more water and time to rinse it out. It also affects the bamboo hoodie for women, where softness is the whole point.

Do the sum for the year

Three washes a week with one krone saved each time comes to a hundred and fifty kroner a year. Not a large sum, but it comes with no effort beyond dosing correctly. Your clothes also last longer. That goes for all the bestsellers for women and anything else washed regularly.

Know your water

Water hardness decides how much detergent you need. Soft water needs less, hard water a little more. You can find details about the water in your area from your local water supplier. Once you know, you can dose by the right line on the pack instead of guessing and adding extra to be safe.

Use a measuring cup

It is hard to get the right amount when pouring straight from the bottle. A measuring cup or the dosing ball that comes with it makes it easy to use the same each time. Put a small mark at your usual amount. Dosing then becomes a habit, and you no longer need to think about it with every wash.

Fabric softener is rarely needed

Fabric softener is an extra cost many can do without. It leaves a film on the fabric that can make it less absorbent over time. Bamboo clothing is soft already and needs no help. Skip the softener and you save money and a bottle in the cupboard, while your clothes keep their natural feel.

Lightly worn clothes need little

Most of what goes in the wash is not really dirty, just worn. It needs refreshing, not scrubbing. A low temperature and a small dose are usually enough. If there are stains, treat them one by one before washing rather than raising the dose for the whole load. That is both cheaper and more effective.

Check the result

If clothes smell fresh and feel soft after a wash with half the dose, they are clean enough. If you feel a stiff surface or see white residue, you used too much. Adjust a little at a time until you find the level that suits your machine and water. Then you have the right dose from then on.
