Tips for cleaning an oxygen sensor: 1. Remove the oxygen sensor from the car; 2. Prepare a cleaning solution, typically by dissolving ferric chloride in water and then adding hydrochloric acid to mix; 3. Soak the oxygen sensor in the prepared solution for about 10 to 15 minutes; 4. After soaking, wipe it clean with a clean cloth. When the oxygen sensor turns white, it indicates the cleaning is complete. The oxygen sensor is a sensing component installed on the exhaust pipe of a car engine. It detects the gas ratio in the exhaust and feeds the information back to the car's onboard computer, allowing the vehicle to assess its condition and achieve an optimal driving state.
I have my own method for cleaning the oxygen sensor: find a wind-free and clean spot, first let the engine cool down completely, then remove the oxygen sensor, which is usually located in the exhaust system. Use medical alcohol or a lint-free cloth to gently wipe the sensor head to remove carbon deposits and oil stains—never use a hard brush or chemicals to avoid scratching the internal components. Let it air-dry for about half an hour before reinstalling and securing it properly. This little trick saves money and is eco-friendly, as a dirty sensor can lead to increased fuel consumption and excessive exhaust emissions. Regular cleaning can extend its lifespan by two to three years. However, be cautious—the sensor is very fragile, and improper cleaning may damage the heating element or sensitive parts. It's best to check it every few months and use fuel cleaners to prevent contamination for better results.
