Anne, Towels should be washed without any fabric conditioner at all. You will find this recommended on the washing instructions on most towels. The conditioner leaves a film on fabric that interferes with the drying properties of a towel. Since learning this I don't use conditioner on them any more, just line dry and finish them off in the tumbler which is the best option. Tumble drying softens.
Maggie - would that be white vinegar which you can buy really cheaply? It is useful for all sorts of things. I used to have some but have used it all. Am going to get some more now I know about it for towels. It doesn't smell like fish and chips!!
i've used it for descaling and cleanng the washine machine but i diodn;t knwo wbaout the towels, will give it a go, i;ve been using fabric softner grrrr
will it re fluff un fluffed towels or are they just dead to me now :-)
I have found that towels I previously used fab.soft on have improved with several washes without it, i.e. drying better, and they haven't become less soft. I doubt whether they could ever get back to the fluffy new state though Fluffy. Fluffy, fluffy, fluffy!!!
