Initial Cleaning and Maintenance:

The single most important step for future daily maintenance involves the complete removal of any remaining grout haze and construction dirt from the detailed pattern.

When applying dense, low porosity tiles the joints should be treated with penetrating type sealers, not coatings. Follow the sealer manufacturer’s recommendations and instructions. For grout joints, it is recommended that the joints be initially sealed after 7 to 10 days curing. The primary purpose of a sealer is to render joints less porous and thereby more stain resistant.

The Pewter itself is completely impervious, but the patinas or finishes need to be carefully considered. Abrasive materials and harsh chemicals should not be employed when cleaning pewter decoration as they may cause staining or pitting.

Once initial cleaning has been thoroughly completed, our daily maintenance procedures can be followed for continuous long-lasting beauty.

Daily Maintenance:

Wall surfaces usually require only a simple wiping with room temperature water and a weak dilution of close-to-neutral pH detergent additive.

For floors, general cleaning should be performed first by sweeping or vacuuming, to remove loose soil or other surface contaminants.  Apply a solution of close-to-neutral detergent cleaner, agitating with a soft to medium bristle deck-brush, then remove all residues, mopping with clean water.

Pewter tiles have a dense, low absorptive body that will resist the penetration of contaminants; however, the surface face and grout joints may be adversely affected by harsh cleaners and aggressive scrubbing.

Keeping an area primarily clean, with a regular cleaning regimen, will eliminate all need for more dynamic or aggressive cleaning activities. 

There are several steps that are critical and should always be remembered for the successful maintenance of pewter tiles:

1)	All spills should be cleaned as quickly as possible. Pewter should be washed with a mild (close to neutral pH) detergent and dried as soon as practical after use, to avoid possible staining caused by splashing certain acid liquids or residues such as: tomato, mustard, milk, juices, or other acidic foods or liquids. Do not use ammonia based cleaning products and never use steel wool or scouring pad.
2)	For floors, sweep or vacuum all loose dirt and other foreign materials.
3)	Use only the manufacturer’s recommended dilution of detergents. More is not always better; higher concentrations of detergent in the cleaning solution will only make it more difficult to rinse and potentially leave a residue, which may react with the pewter finish. Rinsing is a critical step in the maintenance procedure. Dry immediately after rinsing to eliminate spotting and use a soft cotton cloth to dry.
4)	For aggressive cleaning of patterns with deeper design elements, use a soft toothbrush or Terry towel and gentle action.  Often the depth of design and color is resulting from an oxidation or lacquers that need to be treated with care.
5)	All surface cleaning and maintenance materials should be selected carefully to ensure they are not coatings and that they will only alter or blacken the surface appearance or adversely affect cleaning.
