Guys, I love my Cera EO, but cleaning with iso alcohol and boiling water doesn't fully clean all the baked on carbon that reduces the capacity and loading ability of the ceramic core, and also decreases performance (vapor production) and flavor. I have opted to open up my EO core to refurbish the ceramic myself. Using a .035" allen wrench that I found at a flea market, I opened it up. Basically unscrew the 4 base screws in the core. This allows you to pull the stack of ceramics outward from the bottom side. After pulling it apart carefully, I find this. (Note: This is the condition of my core after fully cleaning with many rounds of isopropyl alcohol, boiling water, and 20/20/20 burn. Also, no oil has been added yet.)
Wow! Lots of buildup crap on there!
Using my new torch lighter, I hit the ceramic donut stack till it was glowing white. Repeated for the top ceramic wafer. I tried to avoid the steel parts. I noticed that there is another ceramic donut under the top two. I wasn't able to get this perfectly white as I didn't disassemble the stack, perhaps another time. Anybody know how to safely disconnect the heating wire?
This is what it looks like after torching. Nice and clean! You can see the pores in the ceramic that were once filled with black carbon are now empty.
Disclaimer: Please don't attempt this yourself unless you know all the risks involved. I stripped one hex screw and managed to get it out, but this leaves me with three now. Be very careful with the screws as they strip easily and need very LITTLE threading to secure everything together. Remember, the ceramics are brittle too. I believe this will void your core warranty.
EDIT: Got to try it out in the refurbished status. WOW! Just like new! Big
EASY clouds that taste phenomenal. I will be refurbishing the ceramic periodically with a torch now that I see how big of a difference it is. Love this product!
