fresh water and flushing the syringe
several times
Editor's Notes
Then, insert the syringe needle into the middle of your e cig cartridge filler until you are near the bottom of the cartridge. For two-piece Cartomizer, you will want to make sure you avoid damaging the atomizer and insert the syringe needle aiming for the mesh that is inside of the cartomizer tube. Depress your syringe plunger slowly while moving the needle. The goal is to ensure an even fill of your e cig cartridge without overfilling.
You can also put the cap on the syringe and let it remain in the syringe to top off additional cartridges.
