Hi, I am usig Boge lr 2.0 cartomizers with my eGo.  I've read about cleaning by boiling them and letting them dry out for re-use.  I have dedicated cartos for different flavors, so I am not wanting to clean them to change flavors.  I filled them the first time using the push method and keep them topped of daily.  Are there any signs I should be looking for that will let me know they need to be cleaned, or is it even neccessary?  I have refilled one of them about 6 times, and it seems fine so far.  Will cleaning them make last longer?  Should I clean them every so many refills?  
 
I'd appreciate any advice...
