What should I use to lubricate the zip fasteners on my leathers? They are plastic ones. I'm anxious not to use anything that will rot the leather so grease is out, obviously.
Hey, I've just thought- I used to use a leather dressing called something like Ko-Cho-Line, it was a red jelly and came in a tin, I used it on my gloves as well, but not on the zips as such. Does anybody remember/use that, and would it be ok to make my zips zippy once more? The reason I ask is just that it might be that it would clog the zips and make them worse.
Oh, I have tried rubbing them with a candle to get some of the wax on to the teeth but had no luck.
