Pluid is probably one of the strongest flavors that I've tried, along with a couple of Cinnamon red hot flavors. I don't believe you need to make an entire new wick/coil setup with this flavor, but the choice is yours to make.
I would recommend just cleaning your tank with some water. I use a blunt tipped metal needle and syringe, and fill/rinse as needed through the
juice fill hole. You can take a paper towel gently to the current wick to absorb any
juice, and do some dry burns to burn off the char of old burnt
juice. I also gently use one of those soft brushes that come with hair/beard clippers to brush out the char from the wick/coil.
