What is the recommended method for cleaning magnesium engine parts?

Washing magnesium engine parts with a commercial solvent is recommended because these solvents are designed to gently remove contaminants without reacting with the magnesium or causing surface damage. Commercial solvents effectively dissolve oils, greases, and other residues commonly found on engine components, ensuring that the parts are cleaned thoroughly while maintaining their structural integrity. This method minimizes the risk of corrosion and is safe for the material properties of magnesium.

Other methods, such as using hydrochloric acid, can be aggressive and may lead to corrosion or damage to the magnesium surface, making it an inappropriate choice. Sandblasting with aluminum oxide could also change the surface finish of the magnesium components, potentially leading to stress concentrations or weakening the part. Soaking in water is not effective for cleaning grease and oil, and it may risk corrosion if the parts are not dried appropriately afterward. Therefore, using a commercial solvent strikes the right balance of effectiveness while preserving the magnesium parts.
