Cedar shake siding is a popular choice for many homeowners due to its natural beauty and durability. However, like any other type of siding, it requires regular maintenance to keep it looking its best. One common method of cleaning cedar shake siding is power washing. While power washing can be an effective way to remove dirt, grime, and mold, it is important to proceed with caution as it can potentially harm the cedar shake siding if not done correctly. In this article, we will explore the potential risks of power washing cedar shake siding and discuss how to minimize damage.
Understanding the Risks
Power washing involves the use of pressurized water to clean surfaces. While it can be very effective in removing built-up dirt, it can also be quite abrasive. Cedar shake siding, although durable, can be easily damaged if the pressure is too high or if the water stream is directed at an incorrect angle. Some potential risks include:
- Damage to the surface: The high pressure from power washing can cause the cedar shakes to splinter, crack, or break. This not only compromises the aesthetic appeal but also weakens the overall integrity of the siding.
- Water penetration: Cedar shake siding relies on its natural oils and tannins to repel water. Excessive power washing can strip away these natural properties, leading to increased water penetration and potential water damage in the long run.
- Loose or missing shakes: Power washing can dislodge loose or deteriorated cedar shakes. This can create gaps in the siding, allowing water to seep behind it, potentially causing rot and decay.
Minimizing Damage
While power washing can be risky, it can still be safely performed on cedar shake siding with proper precautions and techniques. Here are some tips to minimize the potential harm:
- Pressure adjustment: Ensure that the pressure setting on the power washer is appropriate for cedar shake siding. Low to medium pressure is generally recommended, typically between 500 to 1200 psi (pounds per square inch).
- Angle of attack: Direct the water stream at a downward angle, following the natural slope of the cedar shakes. This helps prevent water from getting trapped behind the siding.
- Distance matters: Maintain a safe distance between the power washer and the siding. Generally, a distance of 6 to 12 inches is recommended. Starting at a greater distance and gradually moving closer can help determine the appropriate distance.
- Pre-soak and detergent: Prior to power washing, pre-soak the siding with water and a mild detergent. This helps soften dirt, algae, and mold, making it easier to remove with lower pressure.
- Test an inconspicuous area: Before power washing the entire siding, test the equipment on a small, inconspicuous area to ensure that no damage occurs. This allows you to evaluate the pressure and technique before committing to the entire process.
Alternative Methods of Cleaning
If you remain concerned about the potential risks of power washing, there are alternative methods of cleaning cedar shake siding that can be less abrasive yet effective. These methods include:
- Hand scrubbing: Using a soft bristle brush, gently scrub the siding with a mild detergent or specialized cleaning solution. Rinse with a garden hose afterward.
- Oxygen bleach mix: Mix oxygen bleach with water according to the manufacturer’s instructions. Apply the solution to the siding and let it sit for a specified period. Rinse thoroughly with a garden hose.
- Professional cleaning: If you are unsure or uncomfortable handling the cleaning yourself, consider hiring a professional who specializes in cleaning cedar shake siding. They have the expertise and equipment necessary to safely clean your siding without causing damage.
Power washing can be an effective method for cleaning cedar shake siding if done correctly. By following the recommended pressure settings, angles, distances, and pre-soaking techniques, the risks can be minimized. However, if you have concerns or are unsure about power washing, alternative methods such as hand scrubbing or professional cleaning can also be considered. Ultimately, the key is to maintain the natural beauty and integrity of cedar shake siding through regular and proper cleaning methods.
