Mother-Ease wraps smell damp

Hi everyone

I've had my Mother Ease Air Flow wraps for six years. They were great until they started smelling damp. I couldn't get the smell out of them even though I tried strip washing and other methods (I forget which now, so long ago!).
I brought them out of the attic today and they still have that smell hanging on them
I don't want to throw them out and buy new unless there is absolutely no way of fixing them.
Does anyone have any ideas please? xxx

You could try leaving them to soak in the bath with washing soap. Rock n green is really good for soaking your nappies . And I have fillied my bath up half way with cold walter mix in half a cup of bleach and soaked them for the night

Thank you! I'll give that a try
