What are the hazards of an engine after dry ice cleaning of carbon deposits?

[OAmy]

Dry ice cleaning of carbon deposits does not harm the engine. In fact, compared to the impact of carbon deposits on the engine, carbon deposits are more harmful. Using dry ice to clean the engine can largely remove carbon deposits from the engine. Compared to lifting the engine cylinder head to clean carbon deposits, the maintenance cost is significantly reduced, and the degree of cleanliness is comparable. Precautions when cleaning the engine with dry ice: For rust removal: Dry ice cleaning primarily uses high pressure to disperse dry ice particles widely, thereby effectively removing dirt from the surface of objects and reducing surface wear. Particularly, the high-pressure impact can dislodge stubborn stains in crevices from the surface, achieving excellent cleaning results. However, due to these advantages, dry ice cleaning also has certain limitations when it comes to removing thick layers of rust. Worker safety concerns: The extreme cold of dry ice can easily cause frostbite, especially during dry ice cleaning when particles are ejected at a speed of 900ft/s, making it impossible for the human body to resist. Therefore, to better protect the safety of cleaning personnel, all protective equipment must be worn before operation. For example, durable gloves and full-face masks should be used to avoid exposing the skin, thereby preventing harm.
