Have had two kinds of color catchers. The first was white fabric with some nap to it. Believe you could use one up to 20 times. Only problem was, if you tossed them in with darks, often the fuzz appeared on your black tee shirts. Removes in the dryer but I don't machine dry a lot of my laundry.
Have used the Bounce color catchers and they seem to work well but haven't really put them to the big test. My question to everyone is sometimes there hardly appears any dye on them. Any harm in letting them dry and reusing? I have considered that they may not be quite as efficient the second time around.
