Get to Know Your Stone

The first step in proper stone care and maintenance is to understand your stone’s geological classification and composition. Marble and other natural stone products are often quite different from each other. Sure, they all come from “rocks”, but not all rocks are created equal! Marble, granite, quartz, and other stones are products of millions of years of evolution. It is easier to care for your stone if you learn about its source and history.

Natural stone is categorized into three basic geological classifications by their respective formation processes: Sedimentary, Metamorphic and igneous. Additionally, stones in each category can be either Calcareous or Siliceous.

Calcareous stone
Composed mainly of calcium carbonate, a chemical compound commonly found in natural stone, shells and pearls. Calcium carbonate is sensitive to acidic solutions so mild, non-acidic cleaners are recommended.

Siliceous stone
Composed primarily of silicates, such as quartz, feldspar, mica, etc. as such, a siliceous stone is generally resistant to most acids found in kitchen settings, although acidic cleaners are still not recommended, as these stones may contain trace levels of minerals that are acid sensitive.

How to Remove a Marble Stain

Sometimes despite out best efforts to do everything right, and give our marble surfaces the care they deserve, something goes wrong. We gaze lovingly at our beautiful marble counter top—and—horror of horrors! A stain spot!

Do not panic. All is not yet lost.

It is possible to remove spot stains all by yourself. Here’s how.

  • Spread some poultice paste onto the stain.
  • Cover the paste with plastic wrap
  • Seal the plastic to the marble with painters tape
  • After the paste dries, usually overnight or about 24 hours, gently scrape the paste off
  • Repeat once more if the stain is still visible

If the stain is still there, or it’s too big or unwieldy to deal with on your own, we are here to help. Get in touch.

Take Good Care of Your Marble

Marble is a wonderful material. It looks great, and it is functional too. But like all good things, marble needs to be properly cared for to be at its best.

There are four important steps to keeping your marble surfaces in their best condition.

  1. Seal
    Well sealed marble helps to prevent staining, and keeps liquids from soaking into the stone. Spill a bit of clean, clear, water onto your marble counter top or floor. If it doesn’t bead, it’s time to seal it.
  2. Protect
    Care for marble just as you would care for a fine wood finish. Be sure to use place mats, coasters, and trivets, and avoid placing food or drink containers directly on the marble surface. Marble is especially sensitive to anything acidic. Vinegar, tomato juice, orange, and other citrus fruits and juices will actually etch marble.
  3. Keep it Clean
    Use a damp cloth or sponge, or use a product specifically designed to clean marble. Never use acidic cleaners or abrasive cleaners. Vinegar might work fine on your windows, but can ruin your nice marble finish!
  4. Remove Stains Immediately
    You can do it carefully yourself using poultice paste, but we recommend calling in an expert to do it for you.
