Scent at times does help at times in my opinion . I believe the original poster is asking about washing away foreign scent . I watched a episode of fishing 411 and they used lemon joy to wash the lure off after every catch to wash away blood and amino acids "his words" . To help catch more fish Which I think is un necessary and stupid and that was my last episode. Sent from my SAMSUNG-SM-J327A using Lake Ontario United mobile app
