I put the color catchers in the lingerie bags in my HE washer and that does the trick. I also use color catchers anytime I wash fabric or any colored clothing and "almost" always have a tinge of color or totally full of color on the color catchers. Now, I know I have seen others say "use them only once" well, after I put them through a wash cycle, I lay them out on the top of the washer or hang them on a clothes hanger to dry out and then I use them again. They do collect color on the second or even a third use. Just saving money for "more" fabric. My 2 cents.
