Instead or removing and cleaning the screen, some people use the Lotus with an empty bowl and vape the residue that has built up on the screen.
There are two ways to remove the screen for cleaning:
1) Use a pin, needle or Exacto blade to pry the screen from the bowl. Insert the point between the bowl and the edge of the screen.
2) Unscrew the plug at the end of the stem and use a bent paper clip to push the screen out.
Once the screen is removed, torch it until the residue stops burning. Clean the screen of ash and replace it.
