Cleaning Procedures and Recommendations
Care and Maintenance from Natural Stone Restoration and Products New Zealand
Keeping the stone free of dust and dry sandy soil will minimize the scratches and wear-patterns that can develop from everyday use of some natural stone, such as marble, limestone and sandstone. Sweep or dust all natural stone surfaces regularly.
Clean natural stone on a regular basis with warm water and a clean, non-abrasive cloth, sponge or micro-fibre mop. In addition, using a neutral cleanser especially formulated for natural stone will help remove soils that normal dusting or damp mopping leave behind. Do not use general purpose cleansers or you may damage the stone or the sealer that has been applied.
Do not use products that contain lemon, vinegar or other acids as these may etch the stone surface. Do not use scouring powders or creams; these products contain abrasives that may scratch the surface also.
Sweeping Stone Floors:
The broom and micro-fibre mops are still a valuable part of everyday maintenance of any floor surface – including stone. It is very important to remove soils from flooring surfaces before they get ground into the floor. Soils are abrasive. The more often soils are removed the longer the floor will retain the original appearance. Use a broom with a bristle that matches your surface. A soft broom or micro-fibre mop is recommended for smooth surfaces. A medium-soft bristle is ideal for textured surfaces.
A good vacuum cleaner with a brush head works better on textured surfaces than a broom and is very efficient. Use a vacuum when large areas are involved as it can be faster than sweeping.
A damp mop or micro-fibre mop is capable of picking up microscopic abrasive soils and potential staining agents. Damp mopping is recommended on a regular basis. This is best to be done after sweeping, dry-mopping or vacuuming.
Washing Stone Floors and Tiles:
It is necessary to wash a stone or tile floor regularly. The job conditions will dictate frequency. The most frequent problems encountered with stone floors are related to the floor simply not getting effectively washed often enough.
Rinsing is one of the most critical steps in regular floor maintenance. Dirty mop water residue is common and a cause for much complaint. A two bucket rinse method is highly effective in keeping floors from greying out due to soil residues.
