Protank 2: Stale aftertaste, every time. What's going on?

[Superhands]

Ever since I've had my protank 2, I've experienced a slowly developing stale aftertaste in my liquids about a day or two after filling. It's infuriating! The vape starts out tasting just awesome, and then slowly the flavor becomes blunted and, yeah, stale. It tastes a bit like the smell of a window AC unit that's been turned on for the first time after a long winter. I've had this issue with multiple flavors by from different manufacturers.

The weird thing is, I can pour that same liquid straight out of the Protank into an MT3 and it tastes fine and never gets stale.

Last night, I gave the Protank an extremely thorough cleaning - brief alcohol soak, pipe cleaner inside the tank and center pipe, water soak, water rinse, and dried with a hairdryer. Filled with fresh 18mg 50/50 peppermint liquid and a brand new coil last night, and it tastes stale less than a day later. What the hell?

I'm really baffled, here, and frustrated because this tank is otherwise a really neat piece of kit. Any advice is appreciated!

This has solved all of my Kanger problems. Especially with thick liquids.

Be careful dry burning as it will melt the insulator and taste burnt. Try it with a fresh head, no dry burning.

Huh. I'll have to give that a go. I've held onto nearly all of my old Kanger heads in the hopes that I'd one day get around to re-wicking them. Using this cotton method looks much, much easier than rebuilding coils from scratch. Thanks for passing that along!

However, there is still the question of why I have this problem with my Protank consistently, but rarely if ever in my MT3's. As I understand it, the coils are nearly identical, built the same way with the same materials.

Regardless, if re-wicking with cotton solves it, then it's solved. I'll give it a shot this weekend.

The only time I get burned hits now is when I make the cotton too dense or don't wet the new wick properly, it's something you get a feel for, you don't want the cotton to be so dense it pulls the coil around with it. When you give a few primer puffs you should see an air bubble come up. The MT3 might have a different draw that pulls the juice through more strongly.

I have Boba's Bounty (100% VG) in a Protank 2 with Aerobase and I've found keeping the air flow closed down most of the way works best even with a cotton wick.

only thing i can think of, airflow might cause the taste to change.
