Hey so I just cleaned out my Protank and its atomizer head. I soaked it in water, let it dry fo a bit and then I dry burned it a few times. The first couple times I dry burned it a bunch of smoke came out and it smelled odd. After a couple short bursts all the coils started lighting up and it stopped smoking, it still has a bit of an odd smell to it though, is this normal? Is it still good to go?
