mine turned black pretty quickly, luckily it didn't fall off...and now about my cera...it turned black
pretty quickly too. I never cleaned it, except to vape it till it wouldn't vape no more (sic) ...
it gets very hot and so still vapes as effectively as it did when new..
I wil have to try an alcohol soak overnight just for giggles..see if it makes a diff..
meanwhile, I cut a star shape design out of some absorbent material like the guy on tv who got his tongue bit off by the hooker sells, you know the stuff? -- so I put it just above the mouth piece and hold it in place with the rubber , position it so theres a gap betwixt the holes, and keep it moist with an eyedropper! ..the effect is astounding! It's night and day between the smooth moist warmth of the blotter and direct vapor..
this is the grease I use to keep the o rings lubed and sliding easily, a tube will last you a life time, at least!
amazon charges a lot for shipping, so try to find it at an electronics store...

)
and don't worry about getting it on you batteries, it won't block the current even though it's called a "dielectric" --
when two metal surfaces make contact the grease is pushed out of the way..many
electricians and phone workers for that matter use Vaseline for the same purpose, to preserve moving electrical contact points from the air and moisture..
in fact it will help the connection by keep the metal from corroding or oxidizing.
you're welcome!

this is another famously good lube for o-rings, , known to be food safe, and won't run up to 600F :

for some reason this link wouldn't post in the preceding post when trying to add it later.. ?
mod note: TIFTFY. Two posts merged. ..thanks! (added another link, worked this time. )
but wait there's more!
Found the perfect size o ring to fit n the bottom of the cera to make it sit upright . It is stable as it's tall structure can be too, I can give it a good 1/2 inch tip and it won't topple over..
the oring is called a "no. 2-211" in my o ring kit, I don't know if that's a universal designation, so the measurements are :
13/16" ID x 1+1/16" OD with a1/8" thick wall.
I simply wrap a piece of white vinyl tape around the bottom to contain the oring. it looks good, and works perfectly.
