I place my ego style mod in my shirt pocket, however the tip is always sticking out, so I don't feel that it's dirty. Plus I carry a paper towel constantly in the same pocket, so that I can wipe it & my hands if e-juice gets on either.
Plus at refills, I always clean the drip tip with alcohol to clean it up good, if not properly cleaned, these will become crusty.
And no, I don't share my mods with anyone, don't want anyone's germs in my mouth or on my tanks. If anyone wants to try my juice, I have two of the iClear top coils, these drip tips are removable & can be washed hot soapy water, which I do after someone uses it. I keep some of the flavors I like the least in those.
