My ecig tank leaked a bit and got some juice on my arrow sense mod. I thought it was clean so I decided to check and see if the battery had any ejuice on it. What I didn't realize was as I was taking it out, there was a smudge of ejuice on the mod still, got on my finger, and when I took the first battery out I noticed I got the ejuice from my hand on the battery wrapping. It wasn't much , I wiped it off, but is it safe to use again? I really didn't want to wipe the battery wrap with a damp tissue or alcohol , I am confused how to clean a battery lololol.
