P.s.. i dont use bleach :)
Answers:    Only wash contained by cold water, turn them inside out when wash, and choose the gentlest cycle you have to use to bring them clean. In the bleach dispenser of your washer donate a about 1/4 cup of white vinegar to them. Vinegar sets contained by color. Hopefully you'll see a huge improvement. Dry them on milieu heat and hold them turned inside out till all finished.
turn them inside out and put in a cup of salt to the washer. the brackish helps bind the color surrounded by the jeans., and that will keep them from vanishing as fast.but they still will eventually
