I'm getting "Deja Vu" now....
There was a long thread not that long ago, with this issue - and LOTS of responses.
Maybe I started it myself - can not remember - but I remember putting pictures of some of my VERY stuck and "forever" destroyed zippers on a travel kitebag.
Also how the less stuck ones worked or not worked after using vinegar as many proposes.
But if I do a search on myself and all related names I can think of, I just get an old thread from 2004 ?
And not the one from this year (or was it last year)
Is something wrong with the search function here ?
Or is the thread deleted ?
Can anyone remember, or maybe find it through the search ?
I can not remember how the thread ended - if it was useful or not - but was about to link to the topic, as there were many contributors to this problem we all experience....
