What do yo mean? Never heard of that.
Do you mean the softening sheets? Just put softner in with the washing powder, or I use the all in one washing liquid with added softener, wrks a treat.
No, it is the sheet you put in when drying to make them smell fresh...I have pillows that I can't get the smell out of! Bounce is the most known i think but lenor also do them.
