I agree. That's where I think there is the most potential for destroying the seal is. I've had some where the initial "thrust" is easy, and some where it seems much harder. I can see where opening that fill hole improperly for the first time can damage its ability to re-seal. That could cause the problems we are hearing about.
I agree. Thats why I have never tried to pull out the seal with the needle. I take them apart, re assemble the base and outer tube then power wash(hot water) them with(baby syringe from CVS/Walmart/etc...$1.xx):
Tube fits fairly tightly inside the adapter(white) tip. Gets the wicks white and have had good luck so far. I've had drops on my battery posts no matter what. I've had more trouble with the 3 ml version(GV) with regards to gurgling than the CE's. Sometimes I can spin the tube on the base a little bit and that seems to help sometimes. BTW, the 3 ml's fit nicely around the outside of the adapter tip too!
So far I've only broken 1 tube and that was because I was not paying attention. Mount the CE on a dead battery, then gently rock the tube, holding near the base, until it slides off. Remove air tube, push out the top seal, re attach outer tube and clean.
Usually 3/4 pumps with HOT water After cleaning, using a small screwdriver I position the wick tips as best I can in their slots, replace the air tube. Let dry! Using a Q tip I moisten the inside of the clear tube and the bottom seal w/VG ( or spit/juice), insert the top seal with indent away from the base into the tube. Then using the base with air tube attached and air tube tip inserted into the top seal, push until everything is back in place.
If the coils look dark I use
this method for Atomizers to re-clean. Re clean with my power wash and try again.
