At PGC, we often field questions from customers, in regards to maintenance & care for both granite and marble countertops. While marble is a relatively hard material, it is not as hard as granite. It is also made up of a different mineral composition and therefore, care & maintenance is somewhat different. Like granite, marble is relatively easy to maintain. The best cleaning solution for both granite and marble is soap and water. Both materials require only that they be cleaned with a soft white cloth, some hot water, and dish soap. Since marble is a calcite-based stone, it has a delicate chemical composition that may interact in a damaging way to some cleaning products, or agents. Spills should be cleaned up promptly on both surfaces, but especially marble, as some acid based foods, or products such as lemons, wine, vinegar, liquors, tomato sauce, perfume, lotions, etc. may actually etch the stone, leaving it dull and possibly rough to the touch. (Please note that this can be even more prominent if the stone is honed.) Water should also be wiped up promptly on marble tops, as it can it can also etch the stone over time. At PGC, we seal all of our marble and granite countertops before leaving our facility, which helps prevent staining.
