The most important thing is to use your jeans for a long time before the initial wash, in order for the wear to end up in the right place. When it is time to wash them, turn them inside out and wash at 30 degrees with a detergent that is adapted to low temperatures, preferably A+ liquid detergent. You can wash jeans together with other heavily colored clothes in similar shades, preferably also inside out. However, you should never wash jeans with white or light-colored clothes. Another tip that helps extend the life of your jeans is to hang them instead of folding. It helps the fibers to recover after being stretched, especially in the knees and rear end.
