Trim the silica cap's slots to allow proper wicking, especially with thick vg juices (dry burnt hits are usually from pinched wicks or gummed up coils)
Resolder the wire when it breaks
when necessary: Remove the drip tip, unscrew the tank, remove the silica cap, rinse everything, blow off excess moisture, screw core (minus silica cap, dril tip, & tank) onto pv, dry burn repeatedly until the coils glow & all the crud stuck to the coils turns white (no you will not burn your wick or create a permanent burnt taste), rinse white ash off then dry burn again to dry off the wick, assemble your clearo & fill with your
juice.
Always be sure to align the top of the silica cap with the bottom of the drip tip by wiggling the post at the bottom of the clearo while tightening down the drip tip
All clearos, cartos, & tanks require some type of PITA tweaking to keep them running smoothly for a while.
