How to Deep Clean Outdoor Patio Pavers

Patios are the workhorses of the backyard, enduring everything from harsh sun and rain to spills and falling leaves. Over time, that accumulation of organic matter and dirt turns vibrant stone into a dull, stained landscape. A proper deep clean isn't just about aesthetics; it clears away the moss and grime that can make your outdoor space slippery and unsafe. Done well, a deep clean resets your hardscape to a blank canvas. You aren't just washing away surface dust; you are digging into the pores of the stone and the joints where weeds and algae hide. By following a structured approach, you ensure the integrity of the sand joints while revealing the true color and texture of your pavers.

1. Sweep Before You Wet. Remove all furniture, planters, and decorative items from the patio surface. Sweep the entire area with a stiff outdoor broom to eliminate loose dirt, leaves, and twigs.
2. Target Problem Spots First. Inspect the surface for specific trouble spots like oil spills or rust marks. Treat these isolated areas with a specialized cleaner before tackling the entire surface.
3. Coat in Even Sections. Mix your paver cleaner with water in a bucket according to the manufacturer's dilution ratio. Pour or spray the solution evenly over the pavers, working in manageable 10-foot by 10-foot sections.
4. Scrub Joints Aggressively. Use a stiff-bristle push broom to scrub the cleaner into the pavers using a circular motion. Focus extra effort on the joints where organic matter accumulates.
5. Blast Away All Residue. Use a garden hose with a spray nozzle to wash away all suds and dirt. Direct the spray toward the edges of the patio to ensure runoff does not pool in the center.
6. Seal Joints With Sand. Once the patio is completely dry, inspect the joints for gaps. Sweep new polymeric sand into the crevices, clear off the excess, and lightly mist with water to activate the binder.
