Patio Stain Removal

Whether your terrace is made up of brick, pavers or concrete, the appearance of a blot, from spills to mud and regardless of what the trigger, can permanently mar the appearance of the surface. There are a variety of methods to take when cleaning these stains from the walls, and different methods will work for different sorts of stains. If unsure, start with mildest strategy and work your way slowly into the harsher areas until the stain is still gone.


Eliminating residue from a spilled soda or a lost hot dog frequently requires little more than a good scrubbing with a gentle remedy like dish water and soap. For these stains, soak a tough-bristle scrub brush in the cleaning solution and scrub directly at the stain, working the suds and water deep to the surface of the terrace. As soon as you’ve scrubbed the entire area thoroughly, rinse it off with clean water from the hose to remove residual soap along with any remaining pieces of blot. If needed, wash again before the stain is completely eliminated.

Mold Stains

Because of constant exposure to the outdoors, patios frequently develop mold and mildew stains. Normally green or black, these substances won’t pose any serious dangers to your family, like mold inside can, but will continue to propagate across the moist surface of the terrace if not washed away. Mix a 10 percent solution of chlorine bleach to water to tackle these stubborn stains. Scrub directly onto the blot with a stiff-bristle scrub brush and rinse thoroughly when completed. When working with powerful chemicals like bleach, wear safety goggles and gloves to protect your skin from the potentially-harmful effects of the chemical.

Mineral Stains

In some terrace surfaces, especially those composed of unsealed bricks or stone, you might start to detect stains that look like rust. These are a result of the mineral deposits in the terrace surface leeching out thanks to water exposure. If those stains mar the surface of the terrace, mix up a solution of one part white vinegar to 3 parts water. This slightly acidic solution will dissolve most mineral residue, as before, scrub directly onto the stain and wash thoroughly when completed. Use a detail abrasive brush attachment on a rotary tool to lift rust from awkward areas where distance limits the capability to scrub.

Power Washing

Running a power washer against your terrace surface will remove nearly any blot thanks to the sheer force of those machines. Nonetheless, these tools can also result in serious damage if used incorrectly, and as a general rule just those with experience working with the tools should make an effort to clean a terrace with them. If you decide to use a pressure washer, then never turn the power up to 3,000 pounds per square inch or more, since this will certainly gouge the surface. Use a fan tip to make certain the spraying power is dispersed evenly across the surface, and maintain the wand at least 6 to 10 inches from the surface to avoid damage.
