How To Clean Out Mold From Your Air Duct Vents
DISCLAIMER: If you have extreme quantities of mold growth, call a professional duct cleaning contractor. It’s safer for them to take on the challenge of removing and deodorizing the air ducts.
1. Use a mold inhibitor and a mold removal cleaning agent
According to cleaning experts, there are many non-toxic, all-natural at-home cleaning methods for mold (using vinegar, lemons, hydrogen peroxide, baking soda, or essential oils).
One tablespoon of detergent, ½ cup of baking soda, and 1 cup of water. For steel and metal surfaces, like air duct vent grills and ductwork, use 1 part bleach to 16 parts water.
Pour the mixture carefully into a spray bottle for easy cleaning.
2. Wear PPE (personal protective equipment)
Mold can be deadly. Wear protection. Experts recommend you wear an N95 mask, rubber gloves, coveralls, and protective eye gear.
3. Turn OFF Your AC And Furnace
You do NOT want mold spores flying around while you’re cleaning. You’ll have safe access to all parts of your HVAC system (drip pan & evaporator coil) and duct system.
4. Choose A removal Method That Works For You
– Rent or buy a fogger machine from a hardware store. This method involves a fine mist of mold-killing solution that is applied across surfaces.
– Scrubber and vacuum. Soak the mold-ridden parts of your ducts with the sponge for five minutes.
Use a bristle brush or scrub rag to remove the mold. Soak up any excess liquid with paper towels. You can also vacuum it up as needed. Remove the mold and air filters by putting them into a thick, black trash bag and sealing it tightly.
5. Apply A Mold Inhibitor Per Package Instructions
Once cleaned, follow the instructions on your old inhibitor pack and apply it to all of your HVAC components to mitigate the chances of new spores popping up.
6. Place New Air Filters
You’ll need a fresh set of air filters. Make sure the old, contaminated ones are properly disposed of.
7. Stay Vigilant For New Mold Growth
If mold starts coming back, you’ll have to repeat the process (again). If it continuously reemerges, you haven’t addressed the root cause of mold growth. That’s where a professional duct cleaning company can help.
