Natural preventive maintenance guide
Cleaning methods
Sweeping: The old fashioned broom is still a valuable part of everyday maintenance of any floor surface – stone included. 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 brush is recommended for smooth surfaces. A medium-soft bristle is ideal for textured surfaces.
Vacuum: A good vacuum cleaner works better on textured surfaces than a broom and is very efficient. Use a vacuum on any horizontal surface when large areas are involved as it is faster than sweeping in most cases.
Damp Poming: A damp mop is capable of picking up microscopic abrasive soils and potential staining agents. Damp mopping is recommended for most smooth surfaces on a regular basis. Best done after sweeping or vacuum.
Washing: It is necessary to wash a 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: 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 graying out due to soil residues.
Cleaning chemicals
Soaps: Natural soaps are low-tech, inexpensive and user friendly. They are also capable of providing a sealing and/or dressing function for stone floors. Vegetable based soaps are best. Specialty soaps formulated for use on stone are highly recommended and desirable on most natural stone floors and other stone surfaces.
Detergents: These are synthetic surface-active agents (surfactants) that are very good at picking up soils and emulsifying grease and oil. They make water “wetter” and more effective for cleaning purposes. The detergent used for stone cleaning should be carefully evaluated for compatibility with the stone. Detergents are typically used with water and may determine the pH of the cleaning solution. Detergents tend to leave the stone very “raw” or absorbent and residues will make water penetration into the stone more effective.
Acids: These are used for removing grout haze, removing mineral dposits and for rust removal. Acidic products attack lime and cement. Use caution with acids and acidic pH products as they attack the polish on marnbles and limestone. Phosphoric acid, citric acid and sulfamoc acid is preferred to muriatic, sulphuric and hydrocloric acids in almost all situations due to safety and control issues.
Abrasives: Abrasives are sometimes useful as a cleaning agent but should be limited to non-polished surfaces. Abrasives may be combined with detergents or soaps for scouring a surface and removing thin layers from the surface. There are many different types of materials used as abrasives – soft abrasives may be composed of nut shells or feldspars, hard abrasives can be silica quartz, carbide or even diamond.
Bleaches: Bleaches are typically oxidizing agents (generate oxygen) and are useful in stain removal. Enzyme types are available which are non-hazardous.
