Stone is a popular and timeless choice for exterior siding because of its durability, versatility, and natural beauty. But over time, even the toughest stones can accumulate dirt, grime, and stains that can dull the appearance of your home. That’s why we’ve put together a set of cleaning tips to help you get your stone siding looking like new again. These tips are easy to follow and require minimal effort, but can make a big difference in the appearance and value of your house. 

1. Identify the type of stone: Before you start cleaning your stone siding, it’s important to identify the type of stone you have. Some types of stone are more susceptible to damage from certain cleaning solutions or methods. You can usually find out what type of stone you have by checking with the manufacturer or installer, or by examining the stone for distinct features such as texture, color, and pattern. Once you know the type of stone, you can choose the right cleaning product or method that won’t harm it.

2. Pre-treat problem areas: If you notice any areas of your stone siding that have stubborn stains, mold, or mildew, it’s a good idea to pre-treat those areas before you clean the rest of the surface. This can help loosen the dirt and make it easier to remove later. You can use a commercial pre-treatment solution or make your own solution by mixing equal parts of water and vinegar or hydrogen peroxide. Apply the solution to the problem areas and let it sit for 15-20 minutes.

3. Use a pressure washer: A pressure washer is a powerful tool that can blast away dirt, grime, and stains from your stone siding quickly and effectively. It’s important to use the right attachment and pressure setting for your particular type of stone to avoid damage. Generally, a pressure setting of 1200-1500 PSI is suitable for most types of stone. Be sure to keep the pressure washer nozzle at least 12 inches away from the surface to avoid damage.

4. Scrub with a soft brush: If you have areas of your stone siding that are particularly dirty or stained, you may need to do some manual scrubbing. However, it’s important to use a soft-bristled brush that won’t scratch or damage the stone. You can use a regular dish brush, a toothbrush, or a specialized stone cleaning brush. Dip the brush in a cleaning solution that’s safe for your stone and gently scrub the problem areas in a circular motion.

5. Rinse thoroughly: After you’ve cleaned your stone siding with a pressure washer and/or a brush, it’s important to rinse it thoroughly with a hose or another source of water. This will remove any remaining dirt, soap, or cleaning solution that could leave a residue or damage your stone. Be sure to rinse from top to bottom, and avoid letting the water pool in any areas that could cause water damage.

Cleaning your stone siding can be an easy and rewarding task if you follow these tips. By identifying the type of stone, pre-treating problem areas, using a pressure washer, scrubbing with a soft brush, and rinsing thoroughly, you can get your stone siding looking like new and protect it from further damage. Regular maintenance and cleaning can also extend the lifespan of your stone siding and enhance the curb appeal of your home.
