I tried to get the smell off these several ways without success. First I soaked them in vinegar for an hour and then rinsed them. That didn't work so I soaked them in windex and dishsoap for 30 minutes. After rinsing carefully - they still stank powerfuly. So I thought maybe there is some adhesive in the tips that isn't dry, so I put them in a tube (from a shopvac) and placed a hair dryer at one end, high fan, medium heat. I left it that way for an HOUR and 20 minutes (blowing out the back door), they got quite warm. The smell outside was terrific, about like walking into a dry cleaner on a pungent day. Even after 80 minutes it still smelled that way! SO then I left them sit for a few days to air out, and they still have that odor. What kind of Chinese chemical is this, and what is it doing in my jumper wires??? It won't go away, so I will have to trash these (I have others on order).
I hope that Amazon will stop these from being sold. I am going to contact them, and the seller. Needless to say that I would give these zero stars if I could.
