An aluminium cleaner is a chemical formulation designed to remove oil, grease, dirt, oxidation, stains, and light corrosion from aluminium surfaces without causing excessive attack on the base metal. It is commonly used before anodizing, powder coating, painting, welding, or assembly.
* Purpose of Aluminium Cleaner
- Removes machining oil and grease.
- Eliminates oxidation (aluminium oxide).
- Cleans fingerprints and dirt.
- Improves paint and powder coating adhesion.
- Produces a clean, uniform metal surface.
* Typical Cleaning Process
- Remove loose dust and debris.
- Apply or immerse the aluminium part in the cleaner.
- Allow the cleaner to act for the recommended time (typically 2–10 minutes).
- Brush lightly if necessary.
- Rinse thoroughly with clean water.
- Dry the surface completely.
- Proceed with phosphating, chromate conversion, anodizing, or painting if required.
