Colour runs are so annoying. That's why many people spend lots of time carefully sorting their laundry into loads of similar colours; often this also leads them to run their washing machines with energy wasting half loads. But using Colour Catcher in your machine prevents colour runs - which means mixed coloureds can be washed together; so you can always run energy efficient full loads (even at 30°C). And running fewer loads saves you time, energy and money.
