You're buying from the wrong dealer then.

This is one of those questions that when asked gets a different answer from everyone who responds , I'd hang the wire outdoors and let the weather do it's thing to it , our higher summer time temps will remove the oil / grease from the wire .

For coyotes it's not as big of a deal they can still get caught when using the wire you mentioned I've done it quite often , as for wolves I don't have first hand knowledge other than feed back from friends , some preset snares out before season and close the loop down and toss it back in the brush until it's needed along a established travel way .

There's another suggestion treat some wire and don't another coil and use both and keep records of which works better for you , I feel that you maybe surprised by the results .

I have never been blessed to be able to snare wolves (none here), but I think you are overthinking it for coyotes. Boil 1x19 snares/wire supports in baking soda or hang outside for a month or so. They will grey/dull up, which is more than sufficient for treatment.

Put your equipment out and let it work for you. Think about this: Wild animals come across thousands of odors a day in their travel routes. I wouldn't overthink it unless you get direct refusals that you can confirm with either tracks or video evidence.

Another thing to consider is the number of diesel fuel or gas and oil , grease that coyotes come across on a regular basis , unless your off of the road system in Alaska or Canada it doesn't spook coyotes very often .

Then there's always some old barbed wire laying out on the ground as well which doesn't set off an alarm for the coyotes ha ha

Due to the fact that folks keep checking this I figured I'd bring it back to the top .
