CFT-Greying Sock
The CFT Greying Sock is an alternative for the discontinued W-Greying Sock.
It is a Soil Ballast Load that can be used to mimic consumer-realistic greying of white fabrics after 25 washes. With the CFT-Greying Sock you only need 5 wash cycles to achieve these greying levels and discriminate between detergent formulations.
