Marble is a natural stone which needs careful maintenance.
Only clean with warm soapy water and a soft cloth.
Never use scourers or other abrasive cleaning agents as this will damage the stone and remove the sealant used to water proof the marble. This will lead to staining and the shiny/matte surface becoming dull and scratched.
Stone is porous. Honed, acid etched, flame textured or bush hammered surfaces are more porous than the polished surface. The porous nature of stone means that stone is susceptible to staining by certain substances as it absorbs moisture.
You should keep surfaces dust free and wipe away any spills immediately. Do not allow surface deposits to build up on stone surface eg. powder detergent, salts, water. Thoroughly rinse and dry the stone surface after washing.
Acids & Alkalis destroy the glossy layer of polish. The polishing process leaves a high glossy layer on the stone surface, and eliminates bigger porous holes. Unpolished surface is more porous, thus more susceptible to stain. Marble could be hand polished by a polishing pad, which could be found at local DIY stores.
Clean stone regularly by using a soft cloth or sponge with a solution of non-abrasive light neutral detergent (PH7) and warm water. Rinse. Dry with a soft cloth. It is advisable to get the professional stone cleaner from local DIY stores and follow the instructions from the cleaner manufacturer.
Do not use the following on your stone: Acidic Tub & Tile Cleaners, Acidic Toilet Bowl Cleaners, Ammonia, Powered Abrasive Cleaners, Soft Paste Cleaners, Vinegar, Alcohol, Window Cleaners, Abrasive Cleaning Pads, Lemon.
Hand Polish the stone surface when necessary. Get the surface a little water, rub the surface with a stone polishing pad to get it hot. While the moisture becomes dry, the surface will regain a glossy layer.
Stone can be scratched by grit. Grit is the main cause of scratches. Do not rub stone with abrasive cleaning materials, scouring powders, steel wool, metal brushes etc.
Stone varies in its strength make-up. Please ensure that sufficient care is taken when attempting to move or lift stone.
Stone can not be rendered impervious to all marking & staining. All Marble stone surfaces are treated with a water repellant sealant which means that a treatment has penetrated the surface of the material in order to help repel liquids. It can only help and does not protect the surface, the only real protection offered is by the polished surface itself.
Stone requires special care. Protect your stone surface with a Professional Stone Sealer regularly. It is advisable to do it at least once a year.
