I still keep the windows at least cracked so I don't fog up the place. It also leaves a film on the windows over time, which sucks. But it doesn't stink the place up like cigarettes do or leave a permanent "smoker" smell. My vape juice smells like donuts, so I consider it an air freshener lol.
Same as (considerate) people do with cigarettes, when I have passengers, I do ask if they mind.
Some rental cars have now added no vaping alongside the no smoking stickers, though.
I've started regarding those as one of those "Scary" signs they put up to scare people into complying, but aren't really all that enforceable unless they sit there and watch you (Or start putting cameras in their cars ig)
The smell just dissipates too quickly, I've even vaped pulling into their parking lot multiple times to drop off the car and still nothing lol
I get the rule for cigarettes, it leaves that nasty smell, that nasty yellow coating, damage from burn marks etc etc. but what's the deal with vapes? It literally does none of those things. Only thing is that annoying windows film, but the only time that shows up (in the time frame of a week or whatever you have it) is if you hot box the shit out of the car lol
It's also significantly easier to clean off the windows/plasticwork than cigarette residue. Vape juice and its byproducts are literally water soluble. Just, like, use some Windex.
Tobacco crud is nearly impossible to remove, especially from cloth upholstery. I inherited my truck from a smoker and despite thoroughly cleaning it multiple times you can still tell when you sit down that it was owned by a smoker, despite the fact that no one has smoked in it for at least a decade. I've decided it's just my beater truck and I don't care. (Crank windows, manual transfer case, AM/FM radio, no CD, etc.)
Did your ever try running an ozone machine in it? Windows rolled up, let that thing go for the longest time the timer will do. Be careful to not breathe it when you open it back up to air out. But this took out a really gross wet dog smell in my house when I first bought it. It neutralizes cat urine odor. You may need to do more than one session, but it may work for you.
