Preventing dark jeans from bleeding?

[mrst2]

I just wash them separately-- either on their own on a quick cycle or with other jeans. I always wash them inside out as well.

I use the Shout Color Catcher sheets when I wash heavily dyed items for the first time. It works really well. Wash items inside out with cold water.

I also add some white vinegar to the wash to help set the color. For additional dye setting, you can iron them after you wash.
