Bluestone is a popular choice for outdoor paving and landscaping due to its durability, slip-resistance, and aesthetic appeal. However, like all natural stones, bluestone can be prone to staining and discoloration, particularly when exposed to the elements. One common cleaning solution that people often turn to is CLR, a popular cleaning product designed to tackle tough stains and mineral deposits. But can you use CLR on bluestone? In this article, we’ll delve into the world of bluestone cleaning and explore the effectiveness and safety of using CLR on this popular paving material.
The Basics of Bluestone
Before we dive into the world of CLR and bluestone, it’s essential to understand the basics of this popular natural stone. Bluestone is a type of sandstone, composed primarily of quartz and feldspar, with a speckled, blue-gray appearance. It’s a metamorphic rock, formed under high pressure and temperature, resulting in a dense and compact stone.
Bluestone is prized for its durability, resistance to weathering, and ability to withstand heavy foot traffic. It’s often used for outdoor paving, walkways, patios, and even indoor flooring. However, like all natural stones, bluestone can be prone to staining, etching, and discoloration, particularly when exposed to acidic substances, oil, or grease.
What is CLR?
CLR is a popular cleaning product designed to tackle tough stains, mineral deposits, and rust on a variety of surfaces. CLR stands for Calcium, Lime, and Rust, and its principal ingredients are sodium hypochlorite, sodium hydroxide, and water.
CLR is commonly used to clean:
- Rust and corrosion on metal surfaces
- Lime scale and mineral deposits on shower doors, tiles, and bathroom fixtures
- Grease and oil stains on concrete and asphalt
- Soap scum and hard water stains on sinks and toilets
CLR is a strong cleaning agent, and its effectiveness lies in its ability to break down and dissolve mineral deposits and stains. However, its strength can also be a double-edged sword, as it can potentially damage certain surfaces.
Using CLR on Bluestone: The Pros and Cons
So, can you use CLR on bluestone? The short answer is: it’s not recommended. While CLR can be effective in removing tough stains and deposits, its strong formula can potentially damage bluestone, particularly if used excessively or without proper preparation.

Alternative Cleaning Methods for Bluestone
So, if CLR is not recommended for cleaning bluestone, what are the alternatives? Here are some effective and safe cleaning methods for bluestone:
Method 1: Mild Soap and Water
A mild soap, such as dish soap or a specialized stone soap, can be used to clean bluestone. Mix the soap with warm water, and use a soft-bristled brush or broom to gently scrub the surface. Rinse thoroughly with clean water to remove any soap residue.
Method 2: Vinegar and Water
A solution of equal parts white vinegar and water can be used to clean bluestone. The acidity in the vinegar helps break down dirt and stains, while the water helps to rinse the surface clean. Apply the solution to the stained area, let it sit for 15-20 minutes, and then rinse with clean water.
Method 3: Baking Soda and Water
For tougher stains, a paste made from baking soda and water can be used. Apply the paste to the stained area, let it sit for 30 minutes to an hour, and then rinse with clean water. The abrasive nature of baking soda helps to scrub away tough stains and dirt.
Best Practices for Cleaning Bluestone
Regardless of the cleaning method you choose, here are some best practices to keep in mind:
- Always test a small, inconspicuous area first to ensure the cleaning solution or product won’t damage the bluestone.
- Use clean water to rinse the surface, as dirty water can redeposit dirt and stains onto the stone.
- Avoid using acidic substances, such as citrus or vinegar, in high concentrations, as they can etch or damage the bluestone.
- Use a soft-bristled brush or broom to gently scrub the surface, avoiding harsh scrubbers or abrasive materials that can scratch the stone.
- Dry the surface thoroughly after cleaning to prevent water spots and stains.
Conclusion
While CLR may seem like a convenient solution for cleaning bluestone, its strong formula can potentially damage this popular natural stone. Instead, opt for mild cleaning methods, such as soap and water, vinegar and water, or baking soda and water. Remember to always test a small area first, use clean water, and avoid acidic substances in high concentrations. By following these best practices, you can keep your bluestone surfaces clean, safe, and looking their best.
In conclusion, while CLR may be effective on other surfaces, it’s not the best choice for cleaning bluestone. Take the time to choose a gentle, effective cleaning method that won’t compromise the integrity of this beautiful natural stone.
Can I use CLR to clean bluestone pavers?
CLR is not recommended for cleaning bluestone pavers. While CLR is a popular cleaning product for removing mineral deposits and rust stains, it’s not suitable for bluestone due to its acidic nature. Bluestone is a type of natural stone that can be damaged by acidic substances, which can cause etching or discoloration.
