This is how I clean out my (Smoketech) clear dual coil cartomizers.
It would work for any carto AFAIK.
Most of these cartos have been in operation for a little over a month now, being constantly rotated through different juice mixes and blends.
Here's how I do it and this pictorial took me MAYBE 15 minutes to clean 6 juice-filled cartos and have them all ready for new assignments.
Sweet.
I have seen several people poo-poo the idea of using a compressor for various reasons.
So if you're not comfortable using it for whatever reason, then don't do it.
My opinion is that it's a fantastic addition to my vaping experience and I wouldn't go backward now if you paid me.
On to the Pics!:
1. This is a bunch of carto's ready for cleaning.
Tops removed w/ a toothpick, Syringe ready, We're ready to go.
2. This is showing the cup of hot distilled water I am going to use.
I put the meat thermometer in there to check temp. for you guys, I had never actually checked temp. before, just nuked it until it was very hot, but not so hot I couldn't work with it.
Too hot will melt/distort the plastic sleeve anyway.
3. Sucking up a syringe-full of hot water.
4. I picked the skankiest carto I had for the pics, it was a carto of Gourmet Vapor's Caramel Macchiato I ordered in double-flavor back when my 'buds were still needing a kick in the pants.
Too strong now, I vaped it a few times, gagged
, and now it's time to clean it back out, reclaim the carto, and move on.
This is a perfect usage example of this cleaning system, I use my cartos for sampling too.
If I don't like it, I just clean it right back out and start over again.
Easy Peasy.
You can see I'm just starting to inject the hot water into the bottom of the carto, it will primarily flush it from the bottom up, but will flush it out of the center hole too.
5. I just keep filling the syringe and flushing over and over, it usually takes about 8-10 syringe-fulls to clean one, but you can do it as many times as you wish.
From one syringe to the next, I continually rotate the carto around, flushing from a different position each time, almost always inserting the syringe all the way down to the bottom of the carto.
6. This is what it looks like once cleaned, but still full of water.
When you see exactly how much water is still left in there, you'll freak out, it's more than you might think and would take a LONG time to evaporate, but we're getting ahead of ourselves now, aren't we?
7. Here's a shot of all of them cleaned out, but still full of water.
I take the tops and toss them into what's left of the hot water to clean them, no pic necessary for that.
8. We've now moved to the garage and the blowout stage.
This is a pic of my compressor, I usually have it attached to a holding tank with filters for shooting lacquer finishes, but remove all that to make it simple and easy for this operation, just needing the hose and a 1/4" air chuck.
Again, if you happen to not approve of this for whatever reason, then don't do it, easy.
I happen to love it.
9. It blows that much out in about 2 seconds, but I let it blow for 30 more to really dry it out, then I switch ends and blow it from the other end. You can blow from either end, it doesn't make much difference really, except once I was holding it on so tight blowing from the top down it actually blew the end off of the carto. I usually don't hold on to them 'that' tight tho, I was 'gettin' extreme' that day, haha! This is showing blowing from the top down.
10. This a pic simply showing blowing it from the bottom up.
11. This is really the 'money shot', showing just how much water comes out of one of these things, and if you're just rinsing and letting dry naturally, just how much water has to evaporate out.
That is a LOT of water to ask to evaporate out on it's own, and shows why this way is so effective, it puts the carto right back into operation immediately as that puppy is DRY now.
12. All cartos clean, dry, and happy now.
Just one more step necessary to ready them for another round of fresh juice and back into rotation.
13. Back to Base Camp with a bottle of rubbing alcohol,a paper towel, and a Sharpie.
14. I take some rubbing alcohol, apply it to the paper towel, and roll the carto in the alcohol to clean the outside of any stray juice and to remove the prior name.
15. A clean carto is a happy carto!
16. And happier yet back snuggled with the 'bros., ready for My Next Juice Mix!
That's it, the whole thing barely took 15 minutes flat to get 6 dirty cartos cleaned out, dried out, and ready for the next go-round.
I don't keep these cartos all full of juices anymore, they stay like this until I feel the need to refill them, I like keeping them this way now as opposed to keeping 10-15 cartos full of various juices, because filling with the syringe only takes 1 minute of itself too, so re-filling is also a breeze.
Hope you enjoyed it, and maybe it will help someone enjoy their vaping experience a little more, it certainly has made mine better.
Thanks Chet for the assist!
