Marble is a metamorphic rock that’s prized for its beauty. A metamorphic rock is one that’s been changed over eons from one type of rock to another, and marble is a form of limestone. Marble can come in many colors from pure white to pure black and the stone is often full of beautiful veins and clouds of different colors. It seems to gather light into itself and doesn’t conduct heat, so homeowners often use it in the area of the kitchen where pastry is made. Marble is often used as statuary and building material and in the home its used as flooring, wall tile and on countertops in the kitchen and the bathroom.
Marble is a relatively soft and porous stone. It’s much softer and more porous than granite and can’t tolerate acids like orange juice or wine being spilled on it without discoloring. Usually, after marble is installed in a building, it also needs to be polished. Marble can be polished by the homeowner or by a professional.
Special equipment isn't needed to polish marble, but first the polisher needs to determine what kind of marble they have. The marble can be natural or cultured. It’s important to know this because this will determine how the marble is polished. Often, a person will be able to tell the difference simply by touching the marble. Natural marble is cool, but cultured marble is room temperature. If the person can’t tell the difference, the marble should be polished as if it’s natural.
First, stains need to be removed from the marble. Often, the stains can be removed with a damp cloth and dishwashing detergent. Tougher stains may need to be removed with a poultice. This can take a few days.
After this, all dirt and dust has to be removed and the marble needs to be dried.
The best polishing solution for marble is simply baking soda and water. It’s applied, allowed to dry for a few hours, then rinsed. After the polishing solution is rinsed, the marble can be dried and buffed with a chamois or microfiber cloth in circular motions. After this, the marble can be sealed to protect it against stains. The sealant might need to be refreshed every one to two years. It’s time to reseal when water no longer beads up on the surface of the stone.
