The best way to care for denim is to wash it as little as possible, always in cold water on a gentle cycle, air dry rather than tumble dry, and repair rather than replace when it wears. A well-cared-for pair of jeans can last decades.

Chances are, your denim gets more wear than almost anything else in your wardrobe. Most of us wear our jeans on repeat, and quality denim is built to go the distance, so why does the average piece of clothing barely make it past two years? Maybe it’s not the jeans letting us down, but how we’re treating them.

How to care for sustainable denim

The fact is, sustainable fashion starts with what’s already in your wardrobe. And if you’re hoping your favourite pair of jeans will stick around for the long haul (ideally forever), here’s how to give them the care they deserve.

With a few simple habits like washing less, drying properly, and storing your denim well can dramatically extend the life of your jeans. While also reducing water use, energy consumption, and fabric breakdown.

Can you put jeans in the freezer?

You might have heard that freezing jeans kills bacteria and freshens them between washes. It’s a popular tip, and it does reduce odour temporarily, but it doesn’t kill all bacteria the way a proper wash does. Hanging denim outside in fresh air and sunlight is more effective and easier. The freezer trick is fine as an occasional refresh, but airing is the better habit.

How often should you wash jeans?

Help extend the life of your jeans and only wash when needed, usually when they start to smell. The experts at Nudie Jeans recommend washing your jeans no more than every ten wears. Spot clean stains with a damp cloth and soap, and hanging them outside in the sunshine will help keep your denim fresh in between washes.

What’s the best way to wash denim?

To help your favourite pair retain the colour you love, wash in cold water using a gentle detergent. Washing in cold water also saves energy (and money), making it better for your jeans, your wallet and the environment.

Should you put jeans in the dryer?

Now, this is important. Do not put your jeans in the dryer! Hot air causes shrinkage and will cause your favourite pair to fade quicker. Give them a shake, turn them inside out and hang them outside to air dry. Skip the iron, the light creases will smooth out with wear.

What’s the best way to store jeans?

By folding your jeans or scrunching them up and chucking them in the corner, you create creases where you don’t want them to be. Hang your jeans by their loops helps your jeans maintain their natural shape and airs them out after wear.

Frequently asked questions about denim care

How often should you wash jeans?

The experts at Nudie Jeans recommend washing no more than every ten wears. Washing too frequently fades colour, breaks down fabric fibres, and shortens the life of the denim. Spot clean small stains with a damp cloth and soap, and air them out between wears.

Does cold water really make a difference when washing jeans?

Yes, hot water causes denim to shrink and fades colour faster. Cold water is gentler on the fabric, helps retain the original fit, and uses considerably less energy than a warm or hot wash.

Can you repair jeans at home?

Small rips and fraying hems are easy to patch or hand-stitch. Iron-on denim patches work well for inner thigh wear, which is where most jeans give out first. For more complex repairs, Nudie Jeans offers free repairs in Sydney and Melbourne, and Nobody Denim has partnered with The Denim Doctor for specialist work.

What causes jeans to fade?

Heat is the main culprit, from hot washes, tumble drying, and direct sun exposure while wet. Washing inside out in cold water and drying in the shade significantly slows fading.
