What is the best way to clean spark plugs?
1 Answers
Methods for cleaning spark plugs are as follows: 1. White vinegar cleaning: Place the spark plugs in a glass container, pour white vinegar until they are fully submerged. For mild carbon deposits, soak for 2-3 hours; for severe cases, soak for 4-5 hours. After soaking, gently scrub with a hard toothbrush to restore their original condition. Shake off the vinegar and let them air dry naturally. 2. Carburetor cleaner: Place the spark plugs head-down in a glass bottle, spray carburetor cleaner into the bottle (be careful with the angle to avoid splashing), ensuring the spark plugs are submerged, then cover the bottle. Since the cleaner is flammable, fire safety precautions are necessary. Wait for about half an hour, then remove the spark plugs from the bottle, spray carburetor cleaner while scrubbing with a toothbrush, and let them air dry or use a hair dryer. 3. Blue toilet cleaner: Soak the spark plug electrodes directly in pure toilet cleaner. You will see a lot of bubbles forming, which is a chemical reaction between the carbon deposits and the cleaner. Leave them in a ventilated area for 10 minutes until the bubbles diminish. If black carbon deposits remain, soak them again, then rinse with white vinegar (avoid water), and let them air dry. 4. Cleaning at a 4S shop or repair shop: This method is the simplest, but usually, they opt to replace rather than clean the spark plugs.
