You need to get the cart stuffing dry before
vaping. That means removing the stuffing and it can be tricky to get it back however it was. I recommend the precut 510 blue stuffing from strictlyejuice.com - cheapest way to try blue foam. It holds its shape and it's easy to rinse out with water and pat totally dry and put back in. On a full fill you can fill the
juice cup 1/2 way with
juice, insert the stuffing tapered end first, push the foam into the juice to wet it, reposition even with the top edge of the juice cup and top off with 1-3 drops (whatever it needs to look just damp on top)
Attys - some people use hot water, some use alcohol (like pure grain) which dries faster than water. I find hot water seems to do a quicker job of cleaning but takes longer to dry.
