Sammy, when you mention that you boiled the atty, do you mean that you literally boiled it?
Here is the process I use to clean the C atomizer. This is the same for both the SR and LR. I clean the SR weekly and the LR every 4-5 days.
Boiling
Yup I boil it. I used a small saucepan with just enough water to cover the atty, bring it to a boil and then throw in the atty and the wick. Take the saucepan off the burner and move it to a cold burner and let it sit for about 10-15 minutes. You will see all the old juice come off the atty and the wick if you watch it. It will stream off in a dark color like tea.
Removing the wick plate
You can take the wick plate off with a small jewelers screwdriver by prying on the flat side of the wick plate a bit and then turn it, pry some more, repeat and it will eventually come off. Make note of the alignment of the wick plate shape with the shape of the ceramic cup inside the atty so you can put it back together the same way. Note I usually do the boil before I take the atty plate off as this makes it less likely that the wick will stick to the atty and pull out of the spike when you take it apart. Take it slow!
Cleaning the wick
After this I use a pair of hemostats to hold the wick plate by the edges (not the spike) and then take a lighter to the exposed wick. I touch the edge of the flame (where it turns from blue to yellow) to the wick and burn off any juice that is left. The wick will turn white. I then rinse it with some water and then use the flame again to dry it. Be careful as it gets hot!
Don't burn your fingers!
Dry burning the atty
For the atty...Blow through the battery end of the atty to get any leftover water out. I do a dry burn with the wick still off. Just place the atty on the base and screw on the cone. Press the button for about 4 seconds until the coil starts to glow and gives off some vapor. Let it rest for a second and then press it again. Keep doing this about 5-6 times until the entire coil glows evenly. Take the atty out and then rinse it with some hot water to get the charred juice off. Sink sprayer with hot water comes in handy for this. Blow through the battery end of the atty to get any leftover water out. You can then repeat the dry burn process to dry the coil and the wick material inside the coil.
Cleaning the cone and the atty base
I also run some hot water through the cone and the atty base to get the dry burn smell off. Take the atty base off your battery and run hot water through it and through the cone. Dry the cone and atty base with a paper towel. I roll the paper towel to a point and stick it in the cone and swirl it around. You can also blow through the atty base to clean out any leftover water.
Putting it back together
After you finish cleaning the wick and the coil you can re-assemble the atty. I use an empty tank with a plastic tank cap. Place a drop or two of e-juice on the wick and also on the atty coil. Stick the spike of the primed wick plate in the tank and press the wick plate back on the atty. Note the shape of the wick plate matches the shape of the ceramic cup in the atty. The atty plate should be flush with the edge of the atomizer making an even surface across.
Place the cleaned atty back on the atty base, screw in the cone, throw on your tank filled with your favorite e-juice and vape away! The cleaned atty should work almost like a new one.
