How To Clean & Disinfect Your Cars A/C & Heating System

Our modern ish little pickup has a filter that has to be hanged out too!
Agree, I would also remove any caben filter as this is done, a wet filter restricts air and contamination can happen, just be mindful the ducked work near the floor/heater box may leak a very little amount of solvent.
This is a great way to get rid of decontamination in your system :thumbsup:
