Hey Tim, I hadn't noticed you were a new forum member...Welcome !
Yes, you can clean these heads and they will last you for a very long time. I have gotten several weeks out of each head I use. I either just run warm tap water over them or throw them in a small glass or bowl of water to let them soak a bit. What ever you prefer. Then let them dry and do what people call a 'dry burn' this is putting it back on your pv and clicking your power button to heat the coils up until you see them glow nicely. It will burn off any of the gunky stuff left there from the cleaning. It won't hurt your head, and you'll be good to go again until next cleaning. Do several short presses on the button, don't hold it for a long time and do this on a low setting (if you have a vv device) There are plenty of posts for how-to do a dry burn here in the forum. I don't always explain real well, I apologize for that. The point is, you can clean these and they will last a long time for you.

You mentioned Gotvapes in your post. Their forum has a lengthy thread on the Splitfires you can read if you haven't already. Quite a few people love these things.
Again, Welcome to the forum
