Carbona Dye Grabber/ Shout Color Catcher
A Dye Grabber is a product made by Carbona to be used in the wash cycle with fabric to keep the colors from fading in to each other.
The terrycloth like fabric piece is good for 20-24 washing before it must be replaced
I have used this product with outstanding results. I first purchased it at Safeway but an currently looking for another off line source.
Until then I am using Shout Color Catcher (24 count) individual dye grabbing sheets- one use only.
