- You can use a cotton dust mop, static duster or feather duster to dust the ceiling, as often as needed, but typically once every 1 to 2 months. If the metal ceiling is located in a room or building where residues may build up, such as in a restaurant or tavern, do not try to dust the areas where residue is heaviest. Dust dry areas of the ceiling and proceed with other cleaning methods for the areas where residue exists.
- A solution of warm water and a mild, nonabrasive dish detergent work well to wash metal ceilings. Use a soft sponge, wiping each portion of the ceiling gently to avoid scratching the surface. Once the surface is washed, use a soft, lint-free towel to dry each area thoroughly.
- Metal ceilings that are constantly exposed to grease, grime, smoke or excessive moisture will need to be cleaned more often to maintain their durability and appearance. Use a grease-cutting dish detergent and warm water to remove built-up grease and nicotine. Gently wash the surface until all residue is gone, then dry with a lint-free towel.
