What are the hazards of edible vinegar spark plugs?Tragedy after spark plug cleaning

The hazard of edible vinegar spark plugs is that the spark plug coating will be dissolved and lose the role of protecting the spark plug. The surface of the spark plug is easily corroded and rusted. There is a coating on the outside of the spark plug metal shell. This protective layer is used to prevent high temperature corrosion, prevent rust, and prevent the spark plug shell and cylinder head from being integrated under high temperature conditions.

Edible vinegar is an acidic substance. If the spark plug is immersed in it, the coating will be destroyed. After the coating falls off, the surface of the spark plug will be easily corroded and rusted, and its firmness will decrease. When the spark plug shell and the cylinder body are integrated , The risk of the spark plug being unable to be screwed out or the spark plug breaking is increased, and the maintenance cost will also be greatly increased at this time.

Tragedy after spark plug cleaning

Some car owners used 5% white vinegar to soak the spark plugs for several hours. Although the carbon deposits were washed away, the coating on the spark plugs was also washed away, and the result was that it was easy to rust. Such spark plugs are also difficult to use. On the one hand, due to the rust of the threaded port, the seal cannot be guaranteed; on the other hand, it may cause the spark plug housing to be integrated with the cylinder head and cannot be removed.

To remove the carbon deposits on the spark plug, follow the correct operation method and do not operate it lightly. If the spark plug is damaged, don't use it again to avoid more serious problems. If the spark plug is integrated with the cylinder head and cannot be removed, the cylinder head can only be replaced.
