Sealing, Cleaning, and Maintaining Your Marble in Denver

Got a fancy new marble floor that you love to show off? Or how about a marble countertop in your bathroom or kitchen? There’s no doubt that marble is a beautiful natural stone addition to any home’s decor, and with the right sealing, cleaning, and maintenance techniques, you can keep yours looking like new.


Marble, like other natural stone, is porous and can stain easily. Setting a drink on a marble surface will leave a ring, and spills from acidic beverages such as fruit juices or sodas will remove the shine (or “etch” the marble) if you have a polished surface. The best way to avoid stains and etching right off the bat is to seal your marble surfaces properly. A protective sealer—while not completely foolproof--can fill in the pores and help to repel spills, so that all you have to do is wipe down the surface. If left unsealed, everyday messes can penetrate the marble surface, leaving behind unsightly stains.

Because marble is composed of limestone, which is highly sensitive to acids (hence the need for sealing), you’ll need to treat your marble with the same respect when it comes to cleaning. Wipe up any spills immediately with a clean, wet cloth, only use a cleaner with a neutral PH or one that’s specifically for use on natural stone, and never use abrasive cleaners. For floors, simply use a dry dust mop to sweep away dirt.

Polishing your new marble countertops or floors is best done with a chamois cloth on a damp surface; the chamois polishes as the surface dries. For a shinier finish, you can try a commercial-grade polish along with a chamois cloth, or even this trick: Wipe your marble with a mixture of 3 tablespoons of baking soda to 1 quart of water and let it dry before rinsing it off. Then moisten a cloth, dip it in crushed chalk, and wipe the surface again. Finally, rinse one more time and dry the surface thoroughly. Avoid using wax to polish, as it can lead to discoloring, especially on white marble. And remember that you can also hire a professional to polish your marble if you’re at all nervous about the DIY techniques. 

Abrasive sand, grit, and dirt which gets tracked in on the bottoms of shoes can scratch a marble floor, as can the metal or plastic wheels on a vacuum cleaner. To minimize the scratching, try using non-slip mats or rugs on the floor, especially around doorways and entrances to high-traffic rooms or the outdoors. It’s also a good idea to use coasters if you plan to set drinks on a marble countertop in the kitchen, or to place toiletries and other personal products on a tray in the bathroom.
