I think I did mine different than most people. What I did...
Scoped inside the AC area.
Soaked the filters with VitalOxide mixed 4:1 in a gallon sprayer
Sprayed inside the intake from front of car
Sprayed all over inside the chamber
Scoped the area again
Sprayed inside again with scope attached to sprayer - I made sure a huge puddle was under my car before I stopped.
Put the soaked filters back in the car. Fan has been running on my car for hours trying to dry it all out. lol
I noticed one thing in the video that I did not like. It "looks" like the evaporator is wrapped in foam. As in between the evaporator and drain there is foam. I captured it well in a video that I'll upload to YouTube in a bit. If Tesla really did this there will always be a problem with this car. Hope I am wrong.
VitalOxide is used to disinfect hospitals and food areas but it can be used for HVAC per
Eliminate mold on HVAC and Air Ducts
EPA Registration Number: 82972-1
DIRECTIONS FOR USE: FOR ANTIMICRIOBIAL CONTROL IN HVAC SYSTEMS AND AIR DUCTS (INCLUDING ODOR CAUSING BACTERIA, MOLD FUNGUS AND ODOR-CAUSING FUNGI)
I have not used Chlorine Dioxide before so I cannot wait to see how this ends.
Before I started spraying I noticed this mess from the area between the air intake and filter. Not sure why there is running stuff there unless it is from manufacturing. Here is a picture from the scope camera. The scope camera has a built in light ring.
Here is a picture of the evaporator. Looks fine to me.
