When it comes to cleaning and maintaining granite surfaces, many homeowners and cleaning professionals reach for baking soda as a natural, non-toxic, and eco-friendly solution. But what exactly does baking soda do to granite? In this article, we’ll dive into the science behind baking soda’s properties and explore its effects on granite surfaces, both positive and negative.
The Properties of Baking Soda
Baking soda, also known as sodium bicarbonate, is a naturally occurring mineral composed of sodium, hydrogen, carbon, and oxygen. It has a unique set of properties that make it an effective cleaning agent:
- pH Level: Baking soda has a pH level of around 8.3, making it a mild base. This means it can neutralize acidic substances and help balance the pH level of a surface.
- Absorbency: Baking soda is highly absorbent, allowing it to soak up liquids and oils effectively.
- Abrasive Properties: Baking soda is a mild abrasive, which helps it lift dirt and grime from surfaces without scratching them.
- Antibacterial and Antifungal Properties: Baking soda has been shown to inhibit the growth of bacteria, fungi, and yeast, making it a popular natural disinfectant.
The Effects of Baking Soda on Granite
So, how do these properties of baking soda affect granite surfaces?
Cleaning and Degreasing
One of the most significant benefits of using baking soda on granite is its ability to effectively clean and degrease the surface. The absorbent properties of baking soda allow it to soak up oils and dirt, making it an excellent natural cleaner. When combined with water, baking soda forms a paste that can be applied to the granite surface, allowing it to lift dirt and grime without scratching the stone.
However, it’s essential to note that baking soda can be too abrasive for some types of granite, particularly those with a honed or matte finish. In these cases, it’s recommended to use a gentler cleaning solution or consult with a professional stone cleaner.
Removing Stains and Etching
Baking soda can also be used to remove stains and etching from granite surfaces. Etching occurs when acidic substances, such as citrus or vinegar, react with the calcium carbonate in the stone, leaving behind a dull, matte finish. Baking soda’s mild abrasive properties can help lift these stains and etch marks, restoring the granite’s natural shine.
In some cases, baking soda may not be enough to completely remove deep stains or etching. In these situations, it’s recommended to consult with a professional stone cleaner or restorer.
Sealing and Protecting
Some people claim that baking soda can help seal and protect granite surfaces. However, this is a common myth. Baking soda does not have the necessary properties to form a protective barrier on the surface of the granite. In fact, using baking soda as a sealant can actually do more harm than good, as it can leave behind a residue that can attract dirt and dust.
If you need to seal your granite surface, it’s recommended to use a high-quality, stone-specific sealant.
Potential Drawbacks of Using Baking Soda on Granite
While baking soda can be an effective cleaning agent for granite, there are some potential drawbacks to consider:
Abrasive Damage
As mentioned earlier, baking soda can be too abrasive for some types of granite, particularly those with a honed or matte finish. Over time, repeated use of baking soda can cause scratches and wear down the stone.
Residue Buildup
If not properly rinsed, baking soda can leave behind a residue on the granite surface. This residue can attract dirt and dust, making the surface appear dull and streaked.
Alkalinity
Baking soda’s high pH level can potentially react with the acidic substances present in some cleaning products or spills, causing an alkaline reaction that can damage the granite.
Best Practices for Using Baking Soda on Granite
If you do decide to use baking soda on your granite surface, here are some best practices to keep in mind:
Always Dilute with Water
To avoid scratching the granite, it’s essential to dilute the baking soda with water to form a paste. This will help reduce the abrasive properties of the baking soda.
Rinse Thoroughly
After cleaning with baking soda, make sure to rinse the surface thoroughly with warm water to remove any residue.
Test a Small Area First
Before using baking soda on your entire granite surface, test it on a small, inconspicuous area to ensure it won’t cause any damage or discoloration.
Use a Soft Cloth or Sponge
When applying the baking soda paste, use a soft cloth or sponge to avoid scratching the granite.
Conclusion
In conclusion, baking soda can be a effective and natural cleaning agent for granite surfaces, but it’s essential to understand its properties and potential drawbacks. By following best practices and using baking soda in moderation, you can keep your granite surfaces clean, shiny, and well-maintained. However, if you’re unsure about using baking soda on your specific type of granite or have deep stains or etching, it’s recommended to consult with a professional stone cleaner or restorer.
