I mainly work with aluminum and hard plastic parts, which means I would need plastic triangles (in fine-cut and maybe medium-cut grades) for light deburring and surface preparation of aluminum, and maybe ceramic media for use on plastic.
Rinse the aluminum with water. Use the Prep Pad and diluted Aluma Prep solution to scrub gently with the grain to remove chalk, oxidation, dirt and any mold etc. Rinse with fresh water until the water sheets off of the metal. Do NOT let the cleaner dry on the surface, it will be more difficult to remove.
