How to Clean the Car Air Conditioner Evaporator Box?

Steps to clean the car air conditioner evaporator box: 1. Remove the air filter and blower of the vehicle to be cleaned. Place a clean water basin under the air conditioner drain outlet at the bottom of the car to collect wastewater. Adjust the endoscope camera bend at the specified position on the cleaning machine to an appropriate angle to clearly understand the location and contamination of the car evaporator box. 2. Load the cleaning agent onto the cleaning gun, position the spray nozzle near the upper part of the evaporator box, and evenly spray the cleaning agent onto the evaporator box. Replace the cleaning agent in the spray gun, and use the high-pressure spray force to form a fan-shaped spray, repeatedly flushing the evaporator box from top to bottom. 3. Pour two 500ml bottles of water into the empty cleaning agent bottle, and repeatedly rinse the evaporator box to remove residual cleaning agent. Finally, evenly spray a long-lasting antibacterial agent for car evaporator boxes onto the evaporator box until it is completely used up. 4. After cleaning, first install the blower and start the car to dry the evaporator box. Then, use an atomizing antibacterial machine to perform atomized sterilization of the air conditioning ducts. With the car running, turn on the air conditioner's internal circulation mode, set the fan speed to maximum, turn off the AC mode, and start the atomized sterilization. Close the car doors; after about 4-5 minutes of duct atomized sterilization, remove the machine and open all four doors for ventilation for about 15 minutes.
I have hands-on experience with cleaning a car's AC evaporator box. Last summer, there was a musty smell in my car, so I decided to do it myself. First, locate the AC air intake, usually behind the glove compartment or near the engine bay, and spray a specialized cleaner inside. After spraying, wait about ten minutes for the foam to dissolve the dirt. Then, turn on the AC fan to dry it out, and the dirt will drain out through the discharge pipe. Finally, clean the drain pipe to prevent clogging. It's crucial to use an anti-mold cleaner—avoid regular sprays to prevent component corrosion. Cleaning it every quarter helps prevent bacterial growth, which can cause odors or allergies. The whole process takes about 20 minutes—saving money and improving health—and the AC feels fresh immediately. Remember to wear gloves for safety.
