So pretty straight forward question here. I just bought a new liquid so i put it in my tank (aspire nauti) , using same head as previous liquid. I only have one spare head left right now. I want to switch out heads because i can still taste a bit of the old liquid (which tasted like an air freshener). But i dont want to be left with no heads if this one i put in goes bonkers on me. Is there a way i can just clean off this head, let it dry and re use it with no old flavor repercussions?
