As a newbie I was wondering what you guys do after a fishing trip, in particular with lures and plugs. After cleaning the rod and reel with tap water, I do the same with my lures and hang them to dry. Then I give them a spray with WD40 to protect any metal parts from corrosion and coats the lure itself. It doesn't put fish off from striking on later trips. Possibly due to fish oil being a key ingredient and maybe even helping. I have in the past sprayed mackerel strips with WD40 when float fishing and it works a treat.
