Hi, I purchased a bottle of 100mg nicotine liquid in PG base and noticed it had a bit of a hot rubber/musty smell. I'm a bit new do making my own juice but have made some before using nicotine in a 50PG/50VG base and didn't recall a smell like that. I wasn't really concerned until I mixed a few 60mg bottles up of juice using the new nicotine and stuck them in the crock-pot for an hour to get a head start on the steeping. I like smelling the juice periodically because it smells good and when I smelled the ones I made up for my wife with 16%nic/ml, it reeked like musty mushrooms and burning tires. The ones I made for myself with 6%nic/ml, the smell was noticeable but not as bad. I let them sit uncovered in the crock pot for 2 hrs, hoping some chemicals would dissipate out of the mix or something but didn't help. I let them sit overnight in the pantry but still can smell that nasty nicotine. My question, has anybody experienced this before and does the smell eventually go away as it steeps longer? Or would adding a "smooth flavor" to my mix or to the nic bottle itself maybe help tame or hide the nasty smell? I haven't tried vaping any of the juice I made because I'm assuming if I can smell it, I can taste it and haven't smelled anything like that before from store-bought or homemade juice in the past. I bought the nic from Liquid Barn and the brand is USA Liquid Nicotine. I sent a customer care message on their website telling them I think the nic may be bad but haven't heard anything yet. I don't want to use the nicotine if it's bad. Would like to here what others have experienced with their nicotine. Thanks
