So only hot water?
Well i just tried it and filling it up, hopefully it tastes good. Trying the Malboro juice.
Edit: Tobacco e-juice smell and taste like soap/perfume... It's really disgusting. Im going to try another oneand cross my fingers i guess. Also there's one vivi noa tank that i just cant get the old taste out of it, water doesnt seem to work, any ideas?
Alcohol is what I have read some people use. I rinse mine very well in very hot water.
