Cleaning, protecting and restoring aluminium or anodised aluminium

Aluminium rapidly forms an oxide coating when exposed to air. Unlike rusting iron, the oxide prevents further reaction and protects the metal below. Abrasive cleaning removes the coating, which then reforms due to reaction with oxygen in the air. Repeated removal of the oxide reduces the thickness and strength of the component.

Avoid wire wool, abrasive cleaners and products like ordinary metal polish or car polish as these are abrasive. Avoid acid or alkaline cleaners.


Use clean fresh water or BoatSheen Wash and Wax.
If there is a grain in the finish, clean with the grain, not against it.


BoatSheen Performance Boat Wax or Best Brazilian Boat Wax help to throw off water and reduce salt marks or hard water marks.


Clean and degrease with BoatSheen Tough Boat Cleaner. Remove stains and corrosion with Boatsheen Propeller Cleaner, testing on a small area first.

Avoid abrasives if possible as these will alter the appearance.
