The Safe and Sensible Guide to Cleaning Natural Stone

Natural stone is a popular choice for countertops, flooring, and other decorative elements in homes and buildings due to its durability, aesthetic appeal, and unique characteristics. However, cleaning natural stone requires care and attention to maintain its beauty and longevity. Using the wrong cleaning products can damage the stone, leading to etching, dulling, or even discoloration. In this article, we will explore what cleaners are safe for natural stone and provide valuable insights on how to clean and maintain your natural stone surfaces.

Understanding Natural Stone

Before diving into the world of cleaners, it’s essential to understand the characteristics of natural stone. Natural stone is a broad term that encompasses various types of stone, including granite, marble, limestone, travertine, slate, and soapstone, among others. Each type of stone has its unique composition, porosity, and sensitivity to chemicals.

Types of Natural Stone

Natural stone can be broadly categorized into two main groups:

  • Calcareous stones: These stones are primarily composed of calcium carbonate, making them vulnerable to acid-based cleaning products. Examples include marble, limestone, travertine, and onyx.
  • Siliceous stones: These stones are primarily composed of silica, making them more resistant to acidic substances. Examples include granite, slate, and quartzite.

What to Avoid When Cleaning Natural Stone

When it comes to cleaning natural stone, it’s crucial to avoid using harsh chemicals, abrasive cleaners, and acidic substances that can damage the stone. Here are some common cleaning products to steer clear of:

Avoid Acidic Substances

Acidic substances, such as:

  • Citrus-based cleaners
  • Vinegar-based cleaners
  • Wine, citrus juice, or other acidic liquids

can etch or dull calcareous stones, leaving behind unsightly marks or discoloration.

Avoid Abrasive Cleaners

Abrasive cleaners, such as:

  • Bleach-based cleaners
  • Scouring powders
  • High-alkaline cleaners

can scratch or wear down the stone surface, leading to a dull, rough finish.

Avoid Harsh Chemicals

Harsh chemicals, such as:

  • Ammonia-based cleaners
  • Quaternary ammonium compounds (quats)
  • Phosphoric acid-based cleaners

can leave behind residues that can damage the stone or affect its sealant.

What Cleaners Are Safe for Natural Stone?

Now that we’ve covered what to avoid, let’s explore the safe and effective cleaning options for natural stone.

Mild Soap-Based Cleaners

Mild soap-based cleaners, specifically designed for natural stone, are a great option. These cleaners are usually pH-neutral, biodegradable, and free of harsh chemicals. Look for cleaners that are:

  • Labeled as “stone-safe” or “natural stone-friendly”
  • Formulated with gentle, non-ionic surfactants
  • Free of ammonia, bleach, and other harsh chemicals

Some popular brands of mild soap-based cleaners for natural stone include:

  • Stone Tech Professional’s Revitalizer Cleaner
  • Laticrete’s Stone & Grout Cleaner
  • Miracle Sealants’ Stone Cleaner

Neutral pH Cleaners

Neutral pH cleaners, with a pH level close to that of water (pH 7), are suitable for most types of natural stone. These cleaners won’t react with the stone or affect its sealant. Look for cleaners with a pH level between 6 and 8.

Stone-Specific Cleaners

If you’re unsure about the type of cleaner to use or the specific needs of your natural stone, consider using a stone-specific cleaner. These cleaners are designed for particular types of stone, such as granite, marble, or limestone, and are formulated to address their unique characteristics.

Additional Tips for Cleaning Natural Stone

In addition to using the right cleaner, here are some additional tips to keep in mind when cleaning natural stone:

Dilute the Cleaner

Always dilute the cleaner according to the manufacturer’s instructions to avoid applying too much chemical to the stone surface.

Use a Microfiber Cloth

Microfiber cloths are gentle on the stone surface and can help prevent scratching or abrasion.

Avoid Using Too Much Water

Use a cleaning solution that is not too wet, as excessive water can seep into the stone’s pores and cause damage.

Dry the Stone

After cleaning, dry the stone thoroughly to prevent water spots.

Seal Your Natural Stone

Sealing your natural stone regularly can help protect it from stains, spills, and damage. Choose a sealant specifically designed for your type of stone and follow the manufacturer’s instructions.

Conclusion

Cleaning natural stone requires care, attention, and the right cleaning products. By understanding the unique characteristics of your natural stone, avoiding harsh chemicals, and using mild soap-based cleaners or neutral pH cleaners, you can maintain the beauty and longevity of your natural stone surfaces. Remember to always follow the manufacturer’s instructions, dilute the cleaner, use a microfiber cloth, avoid using too much water, dry the stone, and seal your natural stone regularly to ensure its long-term health and appearance.

What types of natural stone require special cleaning care?

Some types of natural stone, such as limestone, travertine, and marble, are more porous and sensitive to cleaning products than others. These stones require special care and attention to avoid damaging their surface. It’s essential to identify the type of natural stone you have and research the recommended cleaning methods to ensure you’re using the right techniques and products.

For example, limestone is a highly porous stone that can be damaged by acidic cleaning products, such as those containing citrus or vinegar. Using these products can etch the stone, creating dull marks and discoloration. Instead, opt for a mild, pH-neutral cleaner specifically designed for limestone. Similarly, marble is prone to etching and requires a gentle, non-abrasive cleaner to maintain its shine and protect its surface.

Can I use household cleaners on my natural stone surfaces?

It’s generally not recommended to use household cleaners on natural stone surfaces. Many household cleaners contain harsh chemicals, such as ammonia or bleach, that can damage or discolor the stone. These chemicals can also strip the stone of its protective sealant, leaving it vulnerable to stains and spills.

Instead, opt for a gentle, stone-specific cleaner that’s designed for the type of natural stone you have. These cleaners are formulated to safely and effectively clean the stone without damaging its surface or compromising its appearance. Always read the label and follow the instructions carefully to ensure you’re using the cleaner correctly.

How do I remove stubborn stains from natural stone?

Removing stubborn stains from natural stone requires patience, persistence, and the right cleaning products. First, identify the type of stain you’re dealing with, as this will help you determine the best course of action. For example, oil-based stains may require a different cleaning approach than organic stains.

To remove a stain, start by blotting the area with a clean, absorbent cloth to remove any excess dirt or debris. Then, apply a stain-removing product specifically designed for natural stone, following the manufacturer’s instructions. Be gentle and avoid scrubbing or rubbing too hard, as this can damage the stone. If the stain persists, consider consulting a professional stone restorer for guidance.

Can I use abrasive cleaners or scrubbers on natural stone?

No, it’s not recommended to use abrasive cleaners or scrubbers on natural stone surfaces. These products can scratch or wear down the stone, dulling its appearance and compromising its integrity. Natural stone is a delicate material that requires gentle care and attention to maintain its beauty and longevity.

Instead, opt for soft, non-abrasive cleaning materials, such as microfiber cloths or soft-bristled brushes. These tools are designed to clean the stone without scratching or damaging its surface. Always read the label and follow the manufacturer’s instructions when using any cleaning products or tools to ensure you’re using them correctly.

How often should I clean my natural stone surfaces?

The frequency of cleaning natural stone surfaces depends on the location and usage of the stone. For example, stone floors in high-traffic areas may require more frequent cleaning than stone countertops in a low-traffic kitchen. As a general rule, clean your natural stone surfaces regularly to prevent dirt and grime from building up and causing damage.

A good rule of thumb is to clean your natural stone surfaces at least once a week, using a gentle, stone-specific cleaner. For more frequent cleaning, consider using a cleaner specifically designed for daily or weekly use. Additionally, consider sealing your natural stone surfaces to protect them from stains and spills and make cleaning easier.
