1. Start by turning off your air conditioning system and locating the evaporator at the back of the dashboard. 2. Remove any dust or debris from the evaporator using a vacuum cleaner or compressed air. 3. Create a mixture of warm water and detergent to clean the evaporator, then dampen a soft cloth with it and wipe down all surfaces of the unit to remove any dirt or grime buildup.

4. Rinse away all traces of soap residue with another dampened cloth soaked in plain water, then dry thoroughly using another soft cloth until no moisture remains on either side of the unit’s fins. 5 .

  • Begin by turning off the car’s AC system, and disconnecting the battery to ensure safety
  • Locate the evaporator core under the dashboard and remove any visible debris or dirt surrounding it with a vacuum cleaner or cloth
  • Create a mixture of one part vinegar and four parts water in an empty spray bottle then spray this mixture on all accessible areas of the evaporator core while wearing protective gloves and goggles for your safety
  • Wait 15 minutes before wiping away all residue using a clean rag or towel so that no traces of vinegar are left behind inside the AC system components
  • 5 Use compressed air to clean out any remaining dirt from hard-to-reach places within the evaporator core such as crevices, cracks, etcetera which may have been missed earlier in step 3
  • 6 Reconnect the car’s battery and turn on its AC system to test if cleaning was successful; you should notice fresh air coming through now instead of stale odors!
