Final answer:
To clean bare-metal surfaces and remove MIL-S-8802 sealant, it is important to use cleaners that are suitable for the specific type of metal. For ferrous metals, cleaners with chelating agents, abrasives, and surfactants, including citric and phosphoric acids, are recommended. For stainless steel, nickel, and chromium, lactic, citric, or phosphoric acid cleaners are preferred.
Step-by-step explanation:
When it comes to cleaning bare-metal surfaces and areas where MIL-S-8802 sealant needs to be removed, it is important to use a cleaner that is suitable for the specific type of metal.
For ferrous metals (such as iron and steel), cleaners containing chelating agents, abrasives, and surfactants are recommended. These cleaners often contain citric and phosphoric acids as nonaggressive agents, along with modified fatty alcohols as surfactants.
For stainless steel, nickel, and chromium, lactic, citric, or phosphoric acid cleaners are more appropriate. They may also contain a solvent like mineral spirits. Nonferrous metal cleaners, on the other hand, typically consist of ammonia, ammonium soaps, and chelating agents.
