Final answer:
Corrosion on magnesium parts is best removed with acidic solutions, which contain strong mineral acids and often include additional substances such as surfactants and corrosion inhibitors to protect the metal.
Step-by-step explanation:
Corrosion should be removed from magnesium parts using acidic solutions. Corrosion, a form of oxidation, can be slowed down by various means such as protective coatings, but when it occurs, especially on metals like magnesium, which is used in aircraft and is a reducing agent in the production of other active metals, acidic cleaning agents are the recommended approach for removal. These cleaning agents usually contain strong mineral acids and often include surfactants and corrosion inhibitors to safeguard the metal from further degradation.
Using abrasive materials could potentially damage the magnesium part, water alone is insufficient to remove corrosion effectively, and alkaline solutions are not typically used for this purpose. Hence, for the maintenance and longevity of magnesium components, especially those exposed to harsh conditions like sea water that accelerates corrosion, the correct approach is crucial.
