What solvent is typically used for degreasing engine parts during overhaul?

Mineral spirits solvent is commonly used for degreasing engine parts during overhaul due to its effectiveness in dissolving oils, grease, and other contaminants that accumulate on engine components. It is a petroleum-derived solvent that works well for cleaning metal surfaces without leaving a residue, making it ideal for preparing parts for inspection and reassembly.

The use of mineral spirits helps ensure that all engine surfaces are clean and free from oils or contaminants that could interfere with the fitting and sealing of components necessary for maintaining engine performance and longevity. Additionally, it evaporates relatively quickly, reducing the risk of moisture being trapped on the engine parts after cleaning.

Other solvent types, such as water-mixed and oil-based degreasers, might not provide the same level of cleaning efficiency or could leave residues that may not be suitable for engine maintenance. Chemical-based degreasers, while effective, can sometimes be more aggressive and could risk damaging certain materials or finishes. Therefore, mineral spirits is preferred for its balance of effectiveness, safety, and minimal impact on metal components.
