Available in a range of colours, shapes and sizes, paving stones are used any number of ways including as flooring, sidewalks, retaining walls and as decoration around pools and hot tubs. Like other items that stay outside, paving stones are susceptible to dirt and grime. You don't need special chemicals or tools to maintain paving stones, but you do need to clean the stones to keep dust, dirt and grime from building up on them. If properly maintained, paving stones will last for years.
Sweep any dust, dirt, leaves or debris from your paving stones onto a dust pan or shovel. Place the debris in a trash can. Wear work gloves to keep your hands clean.
Cover any grass, plants or shrubbery near the paving stones with drop cloths or plastic to keep the cleaning solution off the greenery.
Spray the paving stones with water from a water hose to break up any caked-on debris.
Mix ½ gallon household bleach and ½ gallon warm water in a bucket. Stir the mixture with a long-handled brush.
Scrub the paving stones with the bleach-mixture-soaked long-handled brush. Scrub any areas that are stained with extra force.
Spray the paving stones with water from a water hose. Repeat Step 4 and Step 5 if needed.
Uncover any grass, plants or or shrubbery covered with drop cloths or plastic after the cleaning process is complete.
Sealing your paving stones with a sealer is not required but will help in keeping the stones clean and free of efflorescents(salt and water settling on the surface of the stones and other concrete objects). Use a sealer, found in hardware and home improvement stores, that is designed for paving stones and apply the chemical according to the directions and recommendations on the product's container.
