How to Clean Stone Paving

Updated February 21, 2017

Stone paving is a common installation choice for owners of homes and business. The different shapes, sizes and colours of pavers offer countless options that lend charm and style to outdoor patios, courtyards and driveways. Just like other outdoor applications, stone paving is subject to the accumulation of dirt and grime which can dull its appearance. Yet, it can be restored.

Wet the stone paving surface with a water hose and saturate the joints. Allow the surface to dry completely before applying cleaner. This will make it easier to rinse the cleaner away.

Pour 2 gallons of water into a hose-end sprayer and add 1/2 cup of tri-sodium phosphate (TSP) to the water. Stir the powder into the water with a stir stick or long-handled metal spoon.

Spray a 2-by-2 foot section of the stone pavers with a generous layer of TSP solution. Allow the cleaner to soak into the surface for approximately 3 minutes.

Spray the surface again with a light layer of TSP mixture. Scrub the surface with a long-handled scrub brush to remove dirt and grime.

Rinse the section with water from a hose sprayer until no suds are visible. Move to the next section and repeat Steps 3 to 5 until the entire surface has been cleaned.

Tip

If the paving is stained with rust or tar, use rust or tar remover after cleaning the stone paving with TSP. Follow the product's instructions for the specific type of remover you use.

Warning

Do not apply TSP to the paving in direct sunlight during the summer. Do not allow the cleaner to dry on the surface. Keep it wet at all times while cleaning and rinse completely.
