When cleaning a car air conditioner, the following precautions should be taken: 1. Avoid using it under direct sunlight or on high-temperature painted surfaces; 2. Use it in a well-ventilated area; 3. Keep away from high temperatures and open flames during operation; 4. Prevent children from touching or playing with it. The method for cleaning a car air conditioner is as follows: 1. Start the engine and open all windows; 2. Set the air conditioner to external circulation and adjust the fan speed to level 3; 3. Open the hood, use your hand or a newspaper to test the air intake and locate the suction point; 4. Remove the car air filter and shake the air conditioner cleaner well; 5. Press the cleaner button and spray the cleaner into the evaporator from the suction point of the air intake; 6. Turn off the air conditioner and let it sit for 5 to 10 minutes; 7. Turn on the air conditioner, set it to external circulation, adjust the fan speed to level 3, and spray the remaining cleaner into the evaporator; 8. Wait for 5 minutes, then switch the air conditioner to internal circulation; 9. After another 5 minutes, set the air conditioner to external circulation and adjust the fan speed to level 4.
I always clean my car's air conditioning system myself to save some money, but it's quite a meticulous process. The car must be parked with the engine completely shut off and cooled down before removing the glove compartment or locating the air intake vent. Never skimp on quality by using cheap cleaning agents, especially those containing acidic components, as they can corrode plastic parts. I wear disposable gloves and a mask for protection because dust and debris can fly around during spraying, and inhaling them can cause coughing and discomfort. Spray evenly and avoid pouring too much liquid onto electronic components to prevent short circuits, which can be costly to repair. After cleaning, turn on the fan at low speed for fifteen minutes to ensure the air ducts are completely dry, otherwise residual moisture can breed mold and cause unpleasant odors. I also take the opportunity to replace the air filter, which generally needs cleaning every six months. It's best to do this on a dry day, avoiding rainy or humid weather. After all this, the air blowing out feels fresh and cool, making the driving experience much more pleasant.
As a parent with children at home, my top priority when cleaning the car air conditioner is health. It's essential to wear an N95 mask to avoid inhaling cleaning agent fumes or released bacteria and mold. Wait at least half an hour after the engine is turned off before starting. Choose environmentally friendly and non-toxic cleaning agents, and only use them after verifying the non-toxic label on the ingredient list. Control the amount of spray liquid to ensure even coverage of the evaporator without overflowing to surrounding areas. Then, turn on the external circulation fan at the highest speed for a few minutes to thoroughly dry it, as incomplete drying can activate allergens. I clean it once before each spring and summer season change to prevent asthma and coughing. A friendly reminder: wait until the smell dissipates before letting children back in the car, ensuring clean and safe air inside. This step is crucial for vulnerable groups like the elderly and children.
