Aluminium: remove oil, grease or soap film with neutral detergent or emulsion cleaner. Blast lightly with fine abrasive.

Galvanized Surfaces: remove any oil soap film using a neutral detergent. Treat the surface in accordance with a lightly blast with fine abrasive. If galvanizing has been exposed to exterior weathering for 6 months or more, remove zinc corrosion products by mechanical means, like power sander. Remove oil grease with the cleaner.
