How to Clean Sandstone Like A Pro: A Guide From Professionals

Sandstone, a sedimentary rock composed of sand-sized grains of minerals and rock fragments, is prized for its aesthetic appeal in residential and commercial settings, such as flooring, walls, and outdoor paving. Its porous nature, however, makes it susceptible to stains and damage from improper cleaning. This guide will provide a step-by-step approach to cleaning and maintaining sandstone, ensuring it retains its natural beauty and durability.

The need for proper cleaning methods was highlighted in various sources, including Stone Cleaning Methods Best Practices, which discusses the historical lack of specification in cleaning techniques leading to over-treatment. This article aims to address these issues by offering detailed, safe, and effective methods suitable for both interior and exterior sandstone surfaces.

Understanding Sandstone Properties

Sandstone's porosity is a key factor in its cleaning requirements, as it can absorb liquids and become stained, as mentioned in How to Clean Sandstone Properly. This porosity also makes it vulnerable to biological growth like moss and algae, especially outdoors. Different types, such as Indian sandstone and Yorkshire stone, may have varying durability and cleaning needs, with Indian stone being softer and potentially weathering faster, according to Best Practices for Cleaning Sandstone.

To choose appropriate cleaning methods, it's essential to understand the stone's composition and susceptibility to damage from harsh chemicals or high-pressure cleaning. This article will focus on methods that preserve the stone's texture and color, avoiding acids and abrasive tools.

Preparing for Cleaning

Preparation is crucial for effective cleaning. Gather the following supplies:

Soft-bristle brush or broom, to avoid scratching the surface.
pH-neutral cleaner, to prevent damage from acidic or alkaline solutions.
Bucket of warm water for diluting the cleaner and rinsing.
Microfiber cloth or sponge for applying the cleaner, ensuring gentle application.
Protective gear like gloves and goggles, especially when using chemicals.

Always test cleaning products on a small, inconspicuous area to ensure they don't discolor or damage the sandstone, a precaution echoed in multiple sources.

General Cleaning Methods

Cleaning sandstone involves both dry and wet methods, tailored to the level of dirt and staining.

Dry Cleaning

Dry cleaning is ideal for routine maintenance to remove loose dirt and dust:

Use a soft-bristle brush or vacuum cleaner with a soft attachment, as suggested in How to Clean Sandstone, to gently sweep away debris without scratching the surface.

Wet Cleaning

For deeper cleaning, wet methods are necessary:

Mix a small amount of pH-neutral cleaner with warm water, following the manufacturer's instructions, as seen in Professional Sandstone Maintenance.
Dip a microfiber cloth or sponge into the solution, wring out excess water to avoid over-saturation, and gently scrub the surface in a circular motion.
Rinse the surface with clean water to remove any residue, ensuring no cleaning agent remains, as residue can attract dirt.
Dry the surface with a clean cloth or allow it to air dry to prevent water spots.

Removing Stubborn Stains

Stubborn stains require specific treatments, and this guide provides methods for common types:

Oil Stains: Sprinkle baking soda on the stain, add a few drops of water to make a paste, let it sit for 15-20 minutes, then scrub with a soft brush and rinse.

Rust Stains: Mix equal parts water and lemon juice, apply to the stain, let it sit for 10-15 minutes, scrub with a soft brush, and rinse thoroughly.

Food and Drink Stains: Blot up spills immediately with a clean cloth, and if the stain persists, use a mixture of hydrogen peroxide and water (1:1 ratio), apply, let sit for a few minutes, then rinse.

These methods are safe for most sandstones, but always test on a small area first, especially for colored stones, to avoid discoloration.

Cleaning Interior vs. Exterior of Sandstone Surfaces

The approach differs based on location due to exposure to elements:

Interior Sandstone: Regular sweeping or vacuuming removes dirt, and spot cleaning with a damp cloth and mild cleaner is sufficient. Avoid excessive water to prevent damage to floors or walls.
Exterior Sandstone: Use a soft-bristle brush to remove dirt and debris, and for stubborn stains, use a pH-neutral cleaner or soapy water. Rinse thoroughly and allow to dry, considering outdoor exposure to weather.

Exterior surfaces may require more frequent cleaning due to environmental factors like moss and algae.

Rinsing and Drying

Post-cleaning, thorough rinsing is essential to remove all cleaning agents, which could otherwise leave residues or attract dirt:

Use clean water and a sponge or cloth to wipe down the surface.
For large areas, a garden hose can be used, but avoid high pressure to prevent damage.
Dry the surface with a clean cloth or let it air dry to prevent water spots, ensuring no moisture remains.

Sealing the Sandstone

Sealing is crucial for protecting sandstone from stains and simplifying future cleaning:

Choose a sealer appropriate for your sandstone type, such as penetrating or topical, with options like those from Stain-Proof mentioned in the same source.
Follow the manufacturer's instructions for application, typically using a brush or roller for even coverage.
Allow the sealer to dry completely before use, and re-seal every 1-2 years or as needed, depending on traffic and exposure.

Sealing reduces water absorption, limiting algae and moss growth.

Maintenance Tips

To ensure long-term beauty and durability:

Sweep or vacuum regularly to remove loose dirt.
Wipe up spills immediately to prevent staining.
Use coasters and mats to protect surfaces from acidic substances or hot items, preventing damage.
Avoid harsh chemicals or abrasive cleaners, which can etch the surface.
Re-seal as needed, typically every 1-2 years, to maintain protection..

FAQs for Airbnb Hosts

Can I use bleach to clean sandstone?

Bleach can be used for certain stains, but it's generally not recommended for regular cleaning as it can damage the stone's color or surface. Always test a small area first and use sparingly.

How often should I clean my sandstone?

Regular sweeping or vacuuming should be done weekly, with deep cleaning every few months or as needed based on usage and location.

Can I use a pressure washer on sandstone?

Pressure washers can be used on exterior surfaces, but set to low pressure to avoid damage. Avoid on interior surfaces or delicate types

What's the best way to remove moss from outdoor sandstone?

Mix equal parts water and white vinegar, spray on the moss, let sit for 15-20 minutes, scrub with a soft brush, and rinse.
