Technician A says that any cleaning chemical can be used to clean aluminum parts or components. Technician B says that most chemical cleaners are strong soaps called caustic materials. Which technician is correct?

Technician B is correct

Explanation:

Most of the cleaning agents are usually caustic materials and they're mostly basic in pH (higher than 7) to avoid any form of reaction with the surface/object being cleaned.

Not any cleaning agent can be used to clean aluminum part because some cleaning agent might have reaction or adverse effect when used on aluminum part.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
