Is anyone familiar with the Dr. Beckmann's product?
I did manage to get one box of the Shout Colour Catchers before they quit selling them here in Canada. So far I think Dr. Beckmann's is pretty much doing the same job. They are manufactured in Germany ... and the site is based out of England. So possibilities for others to acquire them.
If you check out their site, they have a whole line of products ... including one to use when fabrics bleed!
