An aluminium cleaner is a chemical formulation used to remove oxidation, dirt, grease, stains, and surface contaminants from aluminium before painting, anodizing, conversion coating, or general maintenance.
- Why Aluminium Needs Special Cleaning
- Aluminium quickly forms a thin layer of Aluminium Oxide when exposed to air. This oxide layer protects the metal but can:
Trap dirt and oils
Cause poor paint adhesion
Affect coating quality
Create a dull or stained appearance.
