They’ll all work, just that your method may be faster. I almost ran out the door to get some fabreeze just now before remembering, my binoculars already don’t smell bad!Tried everything suggested here, didnt help…it worked perfectly.
Some plastics are really bad and you may have gotten the worst ever! At least cigarette odor will fade, eventually.My Fotons 5x25 and 10x40 smelt terribly 23 years ago when new. They still smell so badly I rarely use them.
