Recently cleaned a speaker cloth. But you do have to do as Arran says and remove the cloth from the cardboard. Turns out my wife does work with antique fabric and here's what she suggests: Soak and carefully "swish" it in Ivory Snow using luke warm water. Never squeeze or wring it. Pat dry on a towel and allow it to air dry outside, but in the shade - no sun. It does work pretty well, but if it is badly stained and dirty, you may have to resort to Arran's suggestion - perchloroethelyene...
