Marble and Granite

Natural stone surfaces like marble and granite are important features in many homes, including those serviced by Shrewsbury Marble and Granite. Staining is a common concern for owners, as it can feel like a serious problem on such valued surfaces. The fear of a permanent blemish from a simple spill, like wine or oil, is understandable. However, most stains are treatable if you understand the material and the methods to address them. This is about managing, not just preventing, the results of everyday use.

Why Does Granite Stain?

Granite is a really hard and durable stone, which is why it's so popular. Yet being a natural material, on a microscopic level it contains tiny pores and open spaces. The density of these spaces varies from one granite slab to another. Fabricators apply a sealant to the stone, which is a liquid that soaks in and fills these spaces to act as a barrier. This sealant is what gives you time to wipe up a spill.  

A stain happens when a liquid sits on the surface long enough to get past the sealant and soak into the stone itself. The blemish you see is the staining substance trapped below the surface. This is also why you cannot simply wipe a true stain away; it must be drawn out. The process to remove stains on granite is focused on pulling that trapped substance back out.  

Identifying the Stain Before You Act

Before you can fix a stain, you must know what caused it. Different types of stains respond to different treatments. Applying the wrong one could be useless or even make the problem worse.

  • Oil-Based Stains: These are very common in kitchens. Stains from cooking oil, grease, butter, or even some cosmetics will darken the stone. The spot will look like a permanent wet patch.  
  • Organic Stains:   This group includes most food and drink. Coffee, tea, red wine, fruit juice, or even a wet tea bag left on the counter can leave a pinkish or brownish spot.
  • Metal Stains: Rust is the main culprit here. It is an orange or deep-brown mark, usually caused by a metal object (like the bottom of a shaving cream can or a cast-iron pan) being left on a wet counter.
  • Mineral Stains: In areas with hard water, you may see water rings or cloudy spots. These are typically mineral deposits (calcium and magnesium) left on the surface as the water evaporated. These are a surface issue, not an absorbed stain.

The Poultice: The Best Method for How to Get Stains Out of Granite

For the most common absorbed stains (oil and organic), the most effective solution is a poultice. A poultice is simply a thick, absorbent paste that is applied to the stain. As the paste dries, it pulls the stain out of the stone's pores, a process known as capillary action.

The key to how to get stains out of granite is using the right poultice ingredients. You need an absorbent powder (like baking soda, plain white flour, or kaolin clay) and a liquid reactant.

  1. For Oil Stains: The process to remove stains on granite that is oil-based is often simple. Make a thick paste of baking soda and a small amount of water, just enough to make it the consistency of peanut butter.
  2. For Organic Stains: For coffee, tea, or wine, the liquid reactant is usually a 12% hydrogen peroxide. Mix this with your absorbent powder.  

Applying the Poultice: 

  1. Generously apply the thick paste directly onto the stain. Overlap the edges of the stain by about an inch. Do not rub it in; just lay it on top, about a quarter-inch thick.
  2. Cover the paste-covered area with plastic wrap. Tape down the edges of the plastic wrap to the counter using masking tape. This step is very important. It seals in the poultice, forcing the liquid to work its way down into the stone instead of evaporating into the air.  
  3. Let it sit. This requires patience. The poultice needs to be left undisturbed for at least 24 to 48 hours.  
  4. After these two days, remove the tape and plastic wrap. Let the poultice paste air-dry completely. It will become hard and dry.  
  5. Once it is fully dry, use a non-metal scraper (like a plastic putty knife or an old credit card) to scrape the dried paste off the surface.  
  6. Clean the area with a pH-neutral stone cleaner and water.  

For very old or dark stains, you may need to repeat this process two or three times. This is the most reliable answer to the question of how to get stains out of granite.

Considerations for Local Homeowners  

For homeowners with marble and granite Massachusetts properties, the local climate and water quality can play a role. Hard water, as mentioned, can cause surface mineral deposits that are often mistaken for stains. Using a squeegee to wipe down counters around the sink after use can help prevent these deposits from forming on marble and granite Massachusetts counters. When you remove stains on granite, always follow up by cleaning the area to remove any poultice residue.

Prevention Is the Best Policy  

The most effective way to deal with stains is to prevent them. The primary defense for all marble & granite surfaces is the sealant. You can test your seal by dripping a small puddle of water on the counter. If the water beads up tightly, the seal is strong. If the water spreads out or darkens the stone, it is time to have the stone resealed.

Beyond sealing, simple habits go a long way.

  • Wipe up spills immediately.  
  • Use coasters for glasses, especially with wine or juice.
  • Use trivets for hot pans.
  • Avoid letting acidic foods (like lemons or vinegar) sit on marble & granite surfaces for long periods.

Knowing how to get stains out of granite removes the fear of using your kitchen. A spill is not a catastrophe; it is just a signal for a straightforward cleaning process. The durability and beauty of marble & granite are meant to be a part of a functioning home, and proper care is just a small part of that.

Conclusion:

Natural stones like Marble and granite are a durable and long-lasting choice. Understanding that it is a natural product with specific properties is the key to its long-term care. A stain is a solvable problem, not a permanent flaw. With the right knowledge, particularly of the poultice method, homeowners can manage their surfaces with confidence. Having this understanding means fully appreciating the investment in their countertops, such as those provided by Shrewsbury Marble and Granite, for many years.
