I think i messed up most of a 30 mg bottle of my favorite juice by using isopropyl 91 % to clean the heads . I generallly rinse with warm water, leave in iso for a few hours and the sinse again thoroughly with warm and air dry over night. But with the aspires it left a horrible taste in the back of my tongue for a long time even after dry burning. So i put a brand new head and still the same. Put the juice back in bottle and washed the whole tank and the new head again without isopropyl. Put the juice back in and still the same result. A third head and still the same until i figured i probably ruined the juice. Oddly enough if the juice is in the tank for a while the first toot is fine but after that the same horrible taste that just sticks to the back of my tongue. I'm guessing that the alcohol on the wick has evaporated.
I have a feeling that the carto like filler material in the heads absorb the alcohol more than the wicks on other clearos
I did the same thing tonight with some 91% IPA, but I did it a little differently:
I rinsed the heck out of the heads (one 1.8 and one 2.1) under hot tap water, then blew into them like clearing an atomizer.
Lots of water came out, so I decided to keep clearing the water out and then did a dry burn.
Once I had all the gunky material burned to the corresponding ash (while switching batteries to keep them cool, I would allow the metal part that houses the head to cool as well to prevent any possible grommet overheating), I immediately dipped the still-scalding (used a dry napkin to undo the head) hot head into the 91% IPA. Repeated the same process with the 1.8 head, which seemed more fickle for some reason.
After swishing them around in the IPA for a few moments, I proceeded to use the sink's sprayer head (very close to the bottom of the drain catch to avoid excessive water spray-back) and blasted them with scalding hot water, making sure to aim into the head. This seemed only to knock the gunk loose and a stinky IPA/dry burn odor was still present.
So...I thought, "What would I do if my kanger heads were still gunked up and I needed to get good waterflow through the head in order to rinse the remaining dry-burn flavor out"?
I was hesitant, but removed the bottom pin of the 1.8 head and inspected it. Two wires were visible, and angled outward enough that I wasn't horribly worried they'd get bent out of shape. I decided to throw all logic aside, tossing them back into the ipa for a few more moments. Figuring that if I'd ruined the taste the damage would have already been done, I removed the heads after another quick swish in the IPA, and held the top directly against the tap.
This produced a more effective rinse directly over the coils, and showed me that these things soak up way more liquid than I had suspected initially.
After carefully re-inserting the base pins, I blew out the remaining (and reeking of dry-burn) water until none remained.
I found that it helped to cover the bottom hole with my finger as to force the water out the sides, since this was the last spot where I could detect water. It took a couple of minutes. I then let them dry a couple minutes and replaced the 2.1 head straight back into the ETS, and sat it upright- bubbles were immediately detected, but I decided to give the abused coil a few minutes to rest while I rested.
I'm just finally sitting down after a long day.
Gimme a sec, will take a toot to see how the 2.1 head turned out.
EDIT: at 3.9v; tastes almost like a brand-new coil. Let's bump it up to 4.3 and see if the flavor changes.
Seems to be performing as I'd expect- the juice I'm using has a tiny bit of caramel base in it, so that tends to cook a little above 4.3- for me, at least.
It's a rather complicated frankenstein blend containing NET Perique (GeJ), Nicquid Daybreak, and a little MVS 'Smooth Tobacco' (I find I absolutely MUST thin my NET's or use a higher PG version or the air holes don't wick fast enough- this is with 50/50 starting in the NET & the other juices are there to mainly thin it out a little).
Hope this helps you a little in your ventures.
Also, if you leave that bottle of juice that has the IPA 'taste' in it open, the stuff will evaporate pretty quickly (it's quite volatile). Just pop the cap off and stick it somewhere nobody will mess with it- preferably somewhere cool and dark. I guess you'd kinda be 'steeping' the IPA out of the juice?
