I did some searching on the forum and couldn't find exactly what I was looking for. I recently started going through my bin of insulated wire to remove the brass clips on the end and about 1 of every 4 I pull brings about a cm of the insulated or exposed copper wire with it. Since I've never scrapped these before, my question is how picky are yards about that small amount of wire? Does it become dirty brass vs. clean? What is the price difference? Is there a better way to remove them than yanking off with pliers? All advice appreciated as this is my current way of passing the time during the coldest weekend of the year.
