Cleaning outdoor brick involves assessing the type of dirt or stain and choosing the appropriate method, ranging from simple washing to using specialized cleaners or mixtures like bleach for biological growth.
Outdoor brick surfaces, such as walls, patios, or walkways, can accumulate dirt, grime, mold, mildew, moss, and other stains over time. Regular cleaning helps maintain their appearance and integrity.
Essential Steps for Cleaning Outdoor Brick
Before starting any cleaning process, it's crucial to prepare the area:
- Clear the Area: Remove furniture, plants, and other items near the brick surface.
- Sweep: Sweep the brick to remove loose dirt, leaves, and debris.
- Protect Surroundings: Cover nearby plants or surfaces that might be sensitive to cleaning solutions.
Cleaning Methods for Different Issues
The best cleaning method depends on the type of stain or dirt present on the brick.
Simple Dirt and Grime
For general dirt and grime, a simple wash with water and mild detergent is often effective.
- Wet the brick thoroughly with a hose.
- Mix a small amount of mild dish soap or general-purpose cleaner with water in a bucket.
- Apply the soapy water to the brick using a brush or sponge.
- Scrub the surface gently to loosen dirt.
- Rinse the brick completely with clean water from a hose.
Stubborn Stains
For more stubborn dirt that doesn't come off with simple washing, you might need a bit more pressure or a stronger cleaner.
- Pressure Washing: Using a pressure washer on a low setting (check the brick and mortar's condition first, as high pressure can cause damage) can effectively remove ingrained dirt. Always test a small, inconspicuous area first.
- Brick Cleaner: Commercial brick cleaners are available for tough stains. Always follow the product instructions carefully and wear appropriate protective gear.
Mold, Mildew, and Moss
Biological growth like mold, mildew, and moss thrives in damp, shaded areas and can cause discoloration and potential surface damage if left untreated.
According to the reference, a bleach mixture is ideal for removing mold, mildew, and moss from exterior brick walls.
Here's how to use a bleach solution for these issues:
- Prepare the Mixture: Combine a tablespoon of bleach with a gallon of warm water in a bucket.
- Apply: Apply the bleach mixture with a sponge to the brick.
- Scrub: Use a scrub brush to tackle hard-to-reach areas or difficult stains where the mold, mildew, or moss is deeply embedded.
- Rinse: Thoroughly rinse the treated area with clean water after scrubbing to remove all traces of the bleach mixture.
Caution: Always handle bleach with care, ensure adequate ventilation, and wear gloves and eye protection. Avoid letting the bleach mixture come into contact with plants or other surfaces that could be damaged.
