The use of marble as a flooring material has increased significantly in recent decades, surprisingly due to the durability of the stones. When marble tile is initially unsightly, it’s treated with an approved stain-resistant sealer, which helps protect the floor for about a decade, after which experts recommend it be resealed.
Marble floors are known to resist most spills, as long as they are cleaned immediately, although strong acidic liquids can cause stains, which can however be removed by professional cleaners. In addition to keeping them constantly shiny, these types of floors are basically maintenance-free.
Basic maintenance tips for marble floors
Daily maintenance of marble floors is as simple as wiping them with hot water and letting them dry afterwards. A suitable manufacturer-approved cleaning fluid may be added to the water, but should be mild, non-bleach, non-caustic and pH neutral. Most hardware and home supply stores carry several brands of cleaning fluids, but when in doubt, look only for those that are clearly marked “suitable for marble floors.”
Liquid or food materials that stain marble tiles
There are some types of foods or liquids that are high in acid and, when spilled on them, can etch or leave a dull mark on the surface. These include lemon juice, orange juice, cranberry juice, tomato, wine, and carbonated beverages.
The dark, cloudy spot can be as small as a quarter or it could be spread over several tiles. One of the main contributors to stains and etch marks are some detergents and cleaning agents that contain acid, and examples of these are tile cleaners, vinegar, Ajax and others. Special care should be taken when transporting foods or liquids with a high acid content. In addition to chemicals and liquids that contain acid, there are also other solutions that contain high levels of bleach or alkalinity, and can also damage marble floors.
Tap water could also have a negative effect on these tiles, as it can contain high levels of chlorine, salt, magnesium, and potassium. When water is used regularly to clean these types of floors, it can cause pitting and yellowing of the tiles. It is important for homeowners to protect the floor by using a top quality sealer.
When cleaning is complete, reseal the floor surface or use a liquid or powder polish, available at a marble dealer, hardware store, or lapidary store. Liquid sealants apply easily, right from the can. Or wet the top with water and sprinkle with powder; rub with a soft, damp cloth or a polishing pad on an electric drill at low speed. This should erase any etching marks left by cleaning the surface with a poultice and restore its shine.
Some marble dealers suggest using a penetrating sealer after cleaning, as the sealer seeps into the pores and prevents stains from penetrating. A caulking is particularly useful in high traffic areas. To maintain marble floors in these areas, reseal the tiles at least two to three times a year.
