I have a evod tank and I purchased some coffee flavor liquid which smelled amazing. So I filled my evod and hit it only to find its probably the grossest thing I've tasted in my life. The smell after burning is just as bad. So I threw away the coil and soaked the tank in alcohol overnight. I threw in a new coil and some fresh orange liquid and still smells and tastes horrible. So I repeated that cleaning process 3 times overnight and even washed it out with soap and water but that horrible taste has embedded itself and I don't want to Waiste money on a new tank as the evod is just my spare when I get bored of the flavor in my protank. Has anybody else experienced this problem? This is the only flavor I haven't been able to get rid of.
