Why your black jeans keep going grey

Five everyday washing mistakes that fade your darks, and the cold-wash habits that actually protect them.

Why your dark clothes keep fading

Black jeans don't fade because the colour is weak, they fade because of how they're washed. Here are the five washing habits doing the damage, and the cold-wash, low-heat approach that actually keeps darks dark.

1. Washing in hot water

Heat opens up the fibres and strips dye out with every wash. It's the single fastest way to turn black jeans grey.

Our advice: wash darks on a cold cycle, every time. It's gentler on dye and on the fabric.

2. Overdrying

Leaving jeans tumbling on high heat long after they're dry bakes fade lines into the fabric and breaks down the fibres faster than any wash cycle.

Our advice: low heat, short cycle, or better still, air dry them flat or on a line.

3. Washing right-side out

The outer surface is where all the friction, rubbing and fading happens. Washing jeans right-side out puts that surface directly in harm's way.

Our advice: always turn jeans and dark tees inside out before they go in the machine.

4. Overloading the machine

A packed drum means jeans rub hard against buttons, zips and each other for the whole cycle. That friction is what wears colour away at the seams and pockets first.

Our advice: give jeans room to move, and wash them separately from zips and heavy fastenings where you can.

5. Using the wrong detergent

Standard powders are often built for whites, with brightening agents and bleach-based ingredients that actively strip colour from dark fabric wash after wash.

Our advice: use a detergent made for dark or colour-safe fabrics, never a bleach-based powder.
