How often should the engine cylinder be cleaned?

[WalkerFitz]

Generally, carbon deposits in the engine cylinder should be cleaned every 30,000 kilometers. Failure to clean the engine compartment can easily lead to accidents: Statistics show that 90% of car spontaneous combustion accidents are caused by the engine. Short circuits in engine wiring or oil leaks can trigger accidents. The engine operates in a high-temperature environment for extended periods, and oil sludge and dust adhering to the wiring and oil lines can easily cause aging and damage, leading to accidents. Method for cleaning the engine compartment: First, use a brush to remove surface dust, especially in the crevices. If dust cannot be brushed off, wipe it with a damp cloth. For stubborn oil stains that cannot be removed with a damp cloth, spray engine cleaner and scrub with a brush, avoiding the wiring connections as much as possible. Finally, rinse with water and wipe clean with a towel.
