Been using my Riva kit for a while now with cartos, here is the problem, I now have about 9 cartos that have been boiled out and dried for a week in the airing cupboard. They do not vape much good anymore as in ...when I fill them up they taste fine for 5 mins then the taste changes like..... chemically......rubbery ....if that makes sense. I tried Black Cat that was ok but now tastes like a clutch burning on a car, My all time favourite Golden Virginia from Paradise was always good but now the last one was pants, Pear Drops from the Alchemists Cupboard vapes ok for about 5 draws then tastes like biscuits. Was thinking of buying some more cartos from Vapescape but I thought that if cartos were boiled up it cleans the coil of residue and brought them back to a useable condition.....What to do.....Do I buy more cartos and bin the ones that I have ? I know that I am a heavy vaper.....maybe I should find some heavy duty cartos
