I can't post a vid for you, but basically :
1.) Take a small pick or paperclip and pull out the top seal. Set it aside.
2.) Screw the carto into a
device, and rock the tube gently forward and side to side, until you are able to slide it off. Set it aside.
3.) Gently pull the stainless steel air tube up, and off the base. set it aside. You should see the coil and wicking now.
4.) Rinse with hot water (dry burns can be done carefully as well at this point.)
5.) If you want bonus points, take a set of nail clippers and trim the wicks even with the outside of the cup. This is entirely optional, but it has improved feeding for me. (I vape mine at 5v....)
6.) Reassemble, reversing your steps. Refill upside down, and vape.
