So before I go to bed I figured I would post an update (The bloog is still awesome, I think I saw a knock off called the Volt out there) and details of a technique I'm trying to save some cash on cartos.
I just boiled out 8 cartos some are newer, but 5 of them are heavily used to the point of either tasting burnt or skunky. I should also mention that I vaped dark juices in a few of these cartos, so they looked brown and burned as well.
I used this method;
The smell really fills the place up, so I was smelling Maple, Strawberry Kiwi and Cigar quite strongly during the first boil, second boil wasn't anywhere near as bad. You can tell the second boil is the "rinse cycle" because the water stays clean and clear.
Overall I will have to wait and see if I have ruined 3 kinda good cartos, or alternatively saved 5 soon to be trash items.
The best part so far is how the Carto looks after it has been fully boiled. Almost Brand new! I was very surprised to see I couldn't tell which carto was newer or older.
I'll leave them to dry during my sleep and see how it goes in the morning
