For Anodized Finishes:
- Clean once a year or as needed with a non acidic or alkaline cleaning product.
- Light scratches may be removed with a light abrasive, such as a Comet or ground pumice.
For Painted Finishes:
- Remove common surface dirt by washing with a normal solution of water and household detergent, followed by a clear water rinse. Use a soft bristle brush. Avoid abrasive cleaners and do not use abrasive materials such as sandpaper, emery paper, steel wool etc. Moderate water pressure with physical rubbing with soft sponges is recommended. Cleaning should be done on the shaded side of the building, or ideally on a mildly cloudy day.
- Remove caulking compound, tars or similar asphaltic products with mild solvents such as mineral spirits, naphta or turpentine followed by a clear water rinse. Avoid stronger solvents. Test a small area first. Do not use excessive or abrasive rubbing.
- Remove mildew with a basic solution of the following: 1/3 cup detergent (Tide, for example) 2/3 cup trisodium phosphate (Soilex, for example) 1 quart sodium hypochloride 5% solution (Clorox, for example) Rinse with clear water immediately
- Remove any alkali stain left from mortar with a 10% muriatic acid solution. Rinse with clear water.
- Mono-Kote Fireproofing Compound should not adhere to the finish and should easily brush off.
- Precautions should be taken to prevent sealants from getting on the painted surface as these may be difficult to remove. If any does get on the surface, it should be removed promptly with a solvent such as alcohol or a naphtha type. Caution: It may be possible for solvents to extract materials from sealants which could stain the painted surface or could prove harmful to sealants. Therefore, test a small area first.
