Sanitizing Your Air Conditioner


Once your air conditioner has been cleaned, it’s time to sanitize it to get rid of any lingering bacteria or mold growth. There are several methods you can use depending on the resources you have available:

  • Bleach – Dilute 1 part bleach in 4 parts water and spray onto surfaces that aren’t painted or metallic until they’re saturated; leave for 10 minutes then rinse off with cool or lukewarm water; allow the area to dry completely before switching back on the power supply.
  • White vinegar – Fill a spray bottle with undiluted white vinegar and spritz onto areas where there may be signs of mildew; leave for 10 minutes then rinse off thoroughly with cool water; allow the area to dry fully before turning back on the electrical power supply.
  • Hydrogen peroxide – This is an ideal solution if there are no metal parts present since hydrogen peroxide can corrode them; just dilute 1 part hydrogen peroxide in 5 parts water and spray onto affected areas; leave for 15 minutes then rinse off with lukewarm water; allow the area to dry thoroughly before re-energizing electric supply.
  • Sterilizing solution – Any type of common sterilizing solution will do here e.g., Lysol toilet cleaner; apply liberally onto affected areas using a cloth either directly or diluted according to instructions on the product label (1 part cleaner + 6 parts water); leave 10 minutes then wipe off/rinse away; leave the area to dry fully prior to powering up again electric supply source.
