Hi Paul, we have cleaned all of ours on CaSam.
We machine washed them on a non-fast colour wash at low temp (40 degrees) and they came out fine.
Main things that I would recommend though are;
– Wash them all together….. then if they do happen to fade etc they will still be uniformed
– Be careful if yours have a “piping”, check that the ends are well sealed to avoid them coming out (they are a B to get back in!)
Regards
Steve
