I use the imse vimse stuff and don't rinse. They've only been a bit sticky if I've used a bit too much lanolin. They're very waterproof then though!
Hopefully Sarah will be on soon and will be more help!
Thats wierd, my Imse Vimse says nothing about vinegar, maybe they have made it thicker or something. I would say not to rinse though! I must admit the first few times they did feel a bit sticky but that soon went after 1 or 2 wears if that and now even after more lanolin they don't.
