I think this, How to Determine if You Have Hard Water: 5 Steps (with Pictures), might be a better way. 
sorry couldnt resist that one. Although i really don't know if there is an easy way to tell, i did use to have a water softener system because of really hard water. It was super weird to get used to because my skin felt slippery when wet. whenever i rinsed with soap, it always felt like the soap never rinsed off.:O :O :O no waaaaaaaaaaaay :O :O :O
Always learning new stuff from you.
Unless you're trolling me :O :O :O

I fill my kayfuns with 4ml at a time. I love going all day without refilling.

Ah, common issue with clones, at least in my experience. Something that I do for aaaall my new attys and works like a charm
1) fully disassemble every. Single. Component.
2) put all o rings and plastic parts aside
3) soak all other parts in newly boiled water + a ton of dawn dishwashing soap for 15 mins
4) at the end of this first soak, use a qtip and use it to scrub all the surfaces and the center post channel inside the atty
5) rinse off, and repeat soak as in part 3
6) at end of soak, rinse and it's ready
Works for me everytimehope that helps!
ETA: I handwash all the plastic or rubber components by hand with warm water and dawn.

Wow, I always just thought it felt like it didnt, never knew it actually didnt.It doesn't I grew up with "egg water" soft water that smells like rotten eggs.
First time i got an RBA I'm it took about 45 minutes of trying to get the soap out. When I finally thought I did the vape tastes like burnt dawn.
Started all over again with bottled.
Best use I've ever had for evian.
If its not the residues, could it be the taste of the cotton? not sure what your actually tasting but the only other funk taste I know of is when there is too much cotton in the coil. This results in a nasty taste for sure.Cool I'll try that. What I did before was soak it in hot water with vinegar in my ultra sonic cleaner but I guess that didn't do the trick. Also I forgot to remove o rings, so they got weird and not very elastic after I took them out. I already refilled that Kfl twice with juice and it still tastes funny... and scratchy wispy throat hit.

I vouche for this guy. I sent him my aqua and he was able to get a great build on it with my super thick VG wta liquid....I don't claim to be someone that can fix all problems with the kayfuns but with mine anyways, it performs awesome 100 percent of the time. I never owned a clone and I'm sure those may have possible issues that is a little harder to get right. I love these devices and love working on them. If anyone is having issues with their kayfun and is about to give up and don't mind paying a couple bucks to send them to me. I would gladly take a look and get it going. Keep in the problematic set up so I can evaluate. I then will try to get working perfectly and let you know why there were issues. I really wouldn't mind even if I was sent 50 of them.

What about soaking in mouthwash? Vodka? Vinegar? Nail polish remover?

I've read quite a few people using vodka and vinegar. I've used vinegar myself once and went back and redid it with dawn to get the vinegar taste out. Not sure if I didn't rinse it well enough or not. Apparently soft water rinses better since I was corrected about my experience up above maybe they can tell you. How I did it wrong and got my nasty Italian body oils all over my kfun when my hands were in latex surgical gloves.
Sorry but I hate when someone tells me that my own experiences are figments of my imagination when I'm just trying to help a new person not have to replicate a crappy experience I had.
I spent 33 years bathing soft water I kind of know how it reach with soap. I do bathe twice a day.
Take my remarks as you will, but they werent directed at you or anyone in particular.. Just MY (more than 33) yrs of bathing in soft water and hard.
Some of you may remember my trials and tribulations with my Russian 91, just ordered $31.02 Kayfun Lite Plus V2 Style Rebuildable Atomizer (4.5ml) - 1:1 clone / stainless steel at FastTech - Worldwide Free Shipping received it today, and wow what an amazing device, 1000x times better than my Russian. Just curious though I don't have the air-hole screw in at all, and the drag is still tight, anything I can do?
