Wash Less
One of the easiest ways to take care of your denim and prolong its lifespan is by washing it less. To maintain the fit and wash, wash your denim every 10 wears or so. If there's a stain, use a damp cloth to remove it instead of putting it through a washing cycle.
Wash Cold
When you do put your denim in the washing machine, wash it cold. Cold water will minimise fading, ensuring the wash you love stays the same. It will also protect against shrinking. Make sure you turn your jeans inside out before putting them in the washing machine. Avoid harsh detergents and cleaning products to preserve the denim's original look, feel and fit.
Dry Naturally
Never, ever put your denim in a tumble dryer. Hot air is the enemy; the lint will break down the denim. Instead, dry them naturally in a well-ventilated room or outside. Doing so will preserve the fit and minimise shrinkage or fabric warping.
