When cleaning magnesium components, which method is NOT recommended?

Washing magnesium components with a solvent is typically a recommended practice, as it helps in effectively removing grease, oils, and other contaminants without causing damage to the metal. In contrast, grinding is not advisable because it can generate excessive heat, potentially igniting magnesium dust and causing a fire hazard. Additionally, it can lead to the production of fine particles that may compromise the integrity of the magnesium components.

Scraping and grit blasting can also risk damaging the surface or creating additional contaminants if not done properly. However, in a controlled manner, grit blasting can be used for surface preparation. The focus on grinding being a harmful method emphasizes the importance of preserving magnesium's structural integrity during cleaning processes and avoiding actions that generate heat or particles that could introduce risks. Thus, understanding the properties of magnesium and the methods employed in its maintenance is crucial in aviation safety and component longevity.
