FINISH CARE MAINTENANCE AND CLEANING
3.a. ANODIZED ALUMINUM CARE AND CLEANING
SOME IMPORTAMTS DO’S & DON’TS:
 DON’T use aggressive alkaline or acid cleaners on aluminum finishes. **
 DON’T use cleaners containing trisodium phosphate, phosphoric acid, hydrochloric acid, hydrofluoric
acid, fluorides, chlorine based cleaners or similar compounds on anodized aluminum surfaces. **
 DON’T mix different types of cleaners.
 DON’T attempt to clean hot, sun-heated surfaces since possible chemical reactions on hot metal
surfaces will be highly accelerated, and cleaning no uniformity can occur. Surfaces cleaned under the-
se adverse conditions can become streaked or stained so that they cannot be restored to their original
appearance.
 DON’T use strong cleaners on other building accessories where it is possible for the cleaner to come
in contact with the painted surface. If an aggressive cleaner is required for some other component of
the building, extreme care must be taken to prevent the cleaner from contacting the aluminum finish.
 DON’T allow muriatic acid (hydrochloric) used for cleaning brick to drip on the aluminum. If this should
occur, the acid should be immediately washed off with clean water.
 DON’T allow cleaning products to dry on the anodized surface or the surrounding surfaces.
 DO follow the manufacturers recommendations for proper mixing and diluting of cleaners.
 DO test clean a small area first.
 DO protect the aluminum from building fallout such as wet plaster, mortar, dust, paint, welding splatter
and the like, during installation.
 DO remove alkaline building materials such as wet plaster and wet mortar immediately and washed
the soiled area with clean water. If these materials are allowed to remain in contact with the anodized
surface for an extended period of time, staining will occur.
 DO rinse off all cleaning products with a high volume of clean water.
