Just looking through DS2's stuff to prepare for imminent DS3. We have loads of muslins still, but probably 95% of them have gone all hard and scratchy. That doesn't matter for what we mainly use them for now (wiping up spills, doll blankets, emergency bib, park swing dryer, potty training accidents etc) but if I am going to use them for the new baby I'd like them to be all soft again. Is there any special way of washing them which would achieve this? If not, I will probably buy some new ones but it does seem like a bit of a waste.
I was going to ask on the cloth nappy section because I'm sure they'd know but I can't find it!
We do not have a tumble drier, if that matters.
