my tail pipes look wet (maybe fuel?)

[chevy joe]

i have duals and both pipes look the same. truck has no issues. starts great. no smoke. uses absolutely no oil between oil changes. im getting 16-18mpg around town and @20mpg highway. idles really smooth. looks like fuel on the end of the pipe to me.
so is this normal or not?

i guess its possible its condensation but it never dries up. i towed my trailer yesterday and got the pipes good and hot and it never dried up. given the tailpipes are a good 20ft from the engine. i wiped it with my finger and smelled it. all it smells like is diesel soot. feels a little slippery between my fingers. my guess is still fuel or oil. looks like its getting worse. still no driveability problems.
should i not worry about it until something happens?

follow my pipe dream here.......lol. so my block heater cord is trashed and i have a new one on the way. so every morning it gets started cold (@ 30'F) and the exhaust has that light blue white haze for the first minute or 2, maybe a little unburned fuel its collecting on the tips and it never gets hot enough to burn it off. you would think if this was the case more of you guys would have this.

ps. ive heard some people talk about starting a cold diesel they say it has a rough idle for a few seconds before the cylinders get warm enough for them all to fire efficently. especially if you have a few weaker glows. my truck doesnt do this. as soon as it fires its smooth as glass. im stumped

Do you use tire shine? Get some carb cleaner and spray it off then wipe it off. Then see if it gets wet again.

[chevy joe]

nope no tire shine. ill go clean it off but im sure it will come back. the inside of the pipes look soaked
