What are the precautions for cleaning up car carbon deposits?

This method can only go to the repair shop or 4S shop, and the cost is relatively high, but the effect is much better than that of fuel additives. The liquid medicine for cleaning bubbles is to remove the spark plug of each cylinder, pour the liquid medicine into the cylinder to clean the bubbles for about 20 minutes, and then draw it out with professional tools after the carbon deposit in the cylinder is almost dissolved.

2. Clean the inside of the engine

Open the oil cover, pour the whole tank of cleaning agent (mixed with old oil), cover the oil cover, ignite the engine at idle speed 10 minutes, and then turn off the engine. There is no need to warm up the car for a long time.

In fact, long-term hot car is similar to idling and short-distance driving, and it is also easy to produce carbon deposition.

4. Clean the throttle

5. Use three-way catalytic cleaner

If you want to thoroughly clean up the carbon deposits in the car, you can use a safe and effective carbon deposit cleaner, which is also the method that many old drivers are using now.
