Other than "pop em in the drier" 
Have been into attic and got down DD2's nappies (they're shaped mothercare terries and some flat terries) am "playing house" today so they're in the machine.
They are hard as a rock and really really rough so have put them in with calgon in the washing powder bit and vinegar in the fabric conditioner bit.
Don't have a drier so they can't go in there.
Any other ideas?
