First impressions matter. When walking past or visiting your office, the first thing people will see is your commercial building’s exterior.
Cleaning the exterior walls of a commercial building is essential to maintain its appearance and structural integrity. However, not all cleaning methods are suitable for every wall material. Selecting the wrong cleaning technique can damage the surface, reduce its lifespan, and lead to costly repairs.
Here’s a guide to choosing the appropriate cleaning approach for various common exterior wall materials.
1. Brick
Brick walls are durable and have a timeless appeal, but they can accumulate dirt, moss, and mildew over time. When cleaning brick, it’s important to avoid abrasive methods that could erode the surface or dislodge the mortar between bricks.
Low-Pressure Washing
Brick is porous, and high-pressure washing can damage its surface. A low-pressure washer, combined with a mild detergent, can remove dirt without harming the brick or mortar.
Hand Scrubbing
For older or more fragile brickwork, hand scrubbing with a stiff brush and a gentle, non-acidic cleaner is ideal. This approach prevents surface wear while effectively cleaning the material.
2. Stucco
Stucco is a plaster-like material often used on exterior walls for its aesthetic appeal and durability. However, it can develop cracks over time, and improper cleaning can exacerbate these issues.
Gentle Pressure Washing
Use a low-pressure setting to avoid damaging the stucco. Pairing this with a mild detergent can help remove grime without harming the surface.
Soft-Bristled Brush
Hand scrubbing with a soft brush is recommended for more delicate or intricately designed stucco finishes. This ensures you can clean cracks and crevices without causing further damage.
3. Vinyl Siding
Vinyl siding is a popular, low-maintenance material, but it is prone to staining from dirt, mildew, and algae. While it’s durable, vinyl can crack if too much pressure is applied during cleaning.
Pressure Washing
Vinyl siding can handle moderate pressure washing, but care must be taken not to apply too much force. Set the washer at low to medium pressure and use a mild cleaning solution to eliminate stains and mildew.
Soft Cloth or Sponge
For more detailed or delicate cleaning, especially around windows and trim, using a soft cloth or sponge with soap and water can effectively clean without scratching the surface.
4. Wood
Wooden exteriors have a warm, natural appeal. However, they require specific care to maintain their beauty and prevent damage from the elements.
Gentle Pressure Washing or Hand Cleaning
Use a low-pressure washer to avoid damaging the wood fibers. Alternatively, hand washing with a soft brush and a wood-safe detergent is ideal for protecting the surface.
Oxygenated Bleach for Mildew
For removing mold or mildew, oxygenated bleach is an effective solution that doesn’t harm the wood like harsher chemicals would. It’s safer for the environment and the wood’s integrity.
Clean Your Exterior Wall Materials Appropriately
Just because your commercial building’s exterior is built to withstand the elements, doesn’t mean that it can be treated as you please. Use the cleaning methods mentioned above to clean your exterior wall materials, and increase their longevity.
