Sorry if this seems a little off topic, but Yzer's pic of his Zmax out on a sunny day made me want to bring this up.
Has anyone noticed that allowing the sun to shine on your e-cig for a just little while causes the e-juice in the tank to change color and/or taste funny afterwards?
I use grape flavor mixed with 50/50 VG/PG which appears clear, and I noticed that if the sun shines on it for a little while, it starts to get yellow, tastes a little different, and I get a harsh throat hit (not in a good way). Ever since I noticed this, I'm forever trying to keep my tank in the shade, especially when I'm driving. Obviously just a minute or two of sun isn't enough to cause this, but if I let the sun shine on it for any length of time (>10 min?) it seems to happen to one degree or another (worse the longer it stays in the sun). I'm wondering if its caused by the ultraviolet light breaking down the juice, or maybe just the heat? It's also possible that my particular mix of e-juice is more susceptible to this.
I always keep my e-juice supplies in the fridge (dark most of the time) since I've heard that the sun can make your e-juice go bad faster. Keeping it cool also seems to help it last longer. I'm just surprised by my experience with how quickly my e-juice can go bad if I'm outside in the sun. I've had to dump the remaining contents of my tank and refill with fresh e-juice on several occasions. I go through 1 or 2 large tanks of juice a day, so I know the juice isn't just getting old. It also never happens if I'm indoors or at home out of the sunlight.
Anyone have a similar experience with your e-juice?
