I've recently had some clothes come out of a wash with gluey stuff on them that won't come off. We couldn't figure out what it was and then DH noticed the same stuff on a colleagues clothes at work (it's not from his work because it's on the dc's clothes too). When he asked her about it she said that she thinks it is part of the plasticy skin of the liquitabs which hasn't dissolved properly because she washes at 30. I just thought it a possibility because we also use them and wash at 30 - has anyone else had this problem?
