Endurism Spotlight: Wool Dryer Balls

A bottle of fabric softener does fifty-five washes, then it is empty. You buy the next one. You have been buying the next one for years.

The money

Robijn softener costs €8,69 for 55 washes. That works out at sixteen cents a load. Run four loads a week and the softness alone costs about thirty euros a year. Over a decade you hand over roughly three hundred euros to make laundry feel soft. Dryer sheets stack on top of that. The empty bottles go in the bin, one after another, forever.

The object

A wool dryer ball is a felted sphere of sheep's wool, about the size of a tennis ball. You throw three or four into the drum with the wet load. They bounce through the clothes and hold them apart. Warm air moves through the laundry instead of around a wet clump. The fibres relax and static falls away. The wash comes out soft. A set of six costs around twelve euros and is rated for a thousand loads.

The math

Put the two habits side by side over ten years. The softener is a bill that never stops. The wool is bought twice and then forgotten.

The balls carry their own small cost. You replace the set every thousand loads or so, around twelve euros each time. Counted that way, the wool still costs you a tenth of the bottle. They also cut drying time by about a quarter. That saving comes straight off the energy bill, on every load, for the life of the ball.

Ownership

The balls get better with use. The wool felts tighter and rolls smoother after the first month. After a thousand loads they begin to shed and pill. You drop in a fresh set for the price of a coffee round. They ask for nothing else: no fragrance refill, no plastic bottle under the sink. A single drop of essential oil on one ball scents the whole load if you want it.

If you never bought softener to begin with, the win is the shorter drying time and the empty shelf. A rack by the window is cheaper still.

Twelve euros of wool ends a bill you have paid on every wash for years.
