Cedar siding adds a beautiful rustic charm to your home, but like all exterior surfaces, it requires regular maintenance to keep it looking its best. Cleaning cedar siding isn’t just about aesthetics; it also extends the life of the wood by preventing decay and damage. This comprehensive guide will walk you through the steps for deep cleaning cedar siding, offer general cleaning tips for different types of cedar, and provide useful insights into choosing the right cleaning materials. Keep your cedar siding looking fresh and vibrant by following these proven strategies.
Deep Cleaning Cedar Siding Instructions – In 4 Easy Steps
Step 1 – Remove Loose Surface Dirt from Wood Siding
Begin by preparing the siding area for cleaning. Use a brush with soft bristles to gently sweep away any loose dirt, dust, and debris. This prevents the dirt from scratching the surface of the wood when the cleaning solutions are applied. Work from the top down to avoid spreading dirt onto cleaned areas.
For areas that are harder to reach, a broom or an extension pole fitted with a soft brush can be handy. Be thorough but gentle to ensure the cedar’s finish isn’t damaged. Cleaning on a mild, overcast day is ideal because it prevents cleaning solutions from drying too quickly under intense sunlight.
Step 2 – Apply Oxygen Bleach
Oxygen bleach is a safe and effective alternative to chlorine bleach. Mix a solution following the manufacturer’s instructions, generally around 1 cup of oxygen bleach to 1 gallon of water. Apply the solution using a spray bottle or garden sprayer, making sure to cover the siding thoroughly.
Allow the solution to sit for about 15 to 30 minutes so it can penetrate and lift the stains and dirt. This method is especially useful for removing mildew and organic stains without causing damage to the wood or causing harmful runoff into the environment.
Step 3 – Apply Oxalic Acid
Oxalic acid is a fantastic solution for removing deeper, more stubborn stains such as rust or tannin bleed from cedar siding. Mix the oxalic acid per the instructions, usually around 1/3 cup to 1 gallon of water. Apply it to the stained areas using a soft brush or sponge.
Let it sit for about 20 minutes before rinsing it off with water. Always wear gloves and eye protection when handling oxalic acid as it can be corrosive. This step restores the cedar’s natural color and prepares it for sealing or staining.
Step 4 – Finish by re-staining the cedar siding
After the cedar siding has dried completely, it’s time to re-stain. Choose a high-quality stain that offers UV protection to enhance the wood’s natural beauty and protect it from the elements. Apply the stain evenly using a brush or sprayer, making sure to follow the wood grain.
Providing another layer of protection, this stain helps resist future dirt and mildew build-up, making maintenance easier. Allow sufficient time for the stain to dry according to the manufacturer’s recommendations, which is typically 24-48 hours.
General Cleaning Instructions
Painted Cedar Siding
Cleaning painted cedar siding requires a delicate approach to avoid damaging the paint. A mixture of mild detergent and water is often sufficient. Apply it with a soft-bristled brush or cloth, working in small sections to prevent the soap from drying and leaving streaks. Rinse gently with water.
Avoid high-pressure washing as it can strip the paint and harm the wood underneath. If dealing with mold or mildew, a specialized cleaner safe for painted surfaces can be used. Always test a small area first to ensure there’s no discoloration or damage.
Naturally Weathered Cedar Siding
Naturally weathered cedar siding demands a more tailored cleaning approach. Mild detergents usually do the trick, but it’s essential to maintain the rustic finish while removing any accumulated grime. Mixing water with a small amount of vegetable oil-based soap can gently cleanse the surface without stripping its natural patina.
Rinse thoroughly to ensure no soap residue remains, which could attract more dirt. Regular maintenance prevents significant dirt build-up, making this task easier over time.
Power Washer
While power washers can be used on cedar siding, caution must be exercised. Too much pressure can damage the wood fibers and remove the surface layer, leading to rough and uneven texture. If using a power washer, select a lower pressure setting and use a fan tip nozzle to distribute the water evenly.
Always keep the nozzle at least 18 inches away from the surface and move it in a consistent sweeping motion to avoid concentrated pressure on a single spot. Test on a small and inconspicuous area first to gauge the impact.
Chlorine Bleach
Chlorine bleach is sometimes used to combat severe mold or mildew issues; however, it can be harsh on cedar siding. It can strip the wood’s natural oils, leaving it dry and brittle, and potentially cause damage to surrounding vegetation. If you must use chlorine bleach, dilute it significantly (a few tablespoons per gallon of water).
Apply carefully with a soft brush, working in small sections. Protect your skin and eyes, and thoroughly rinse the area to remove any residue. Always consider oxygen bleach as a safer, more environmentally friendly alternative.
Detergents
For regular maintenance, mild detergents are your best friend. A simple mix of water and dish soap is usually effective for light cleaning jobs. Apply the solution with a sponge or soft brush, scrubbing gently along the wood grain. Rinse thoroughly with clean water to ensure all detergent is removed.
For tougher stains, a mixture of water, vinegar, and a small amount of dish soap can address mold and mildew without the harshness of bleach. Regular cleaning with these gentle solutions maintains your cedar siding’s appearance and longevity.
To recap how to clean cedar siding:
Cleaning cedar siding is a multi-step process requiring the right knowledge and techniques. From deep cleaning with oxygen and oxalic acids to routine maintenance with mild detergents, each step plays a crucial role in preserving the wood’s integrity and appearance. Whether dealing with painted, weathered, or natural finishes, understanding the right methods and materials ensures that your cedar siding stays beautiful and durable for years to come.
Key Tips For Cleaning & Enhancing Cedar Siding:
Regular maintenance is key. Aim to clean your cedar siding at least once a year to prevent the build-up of dirt, mildew, and other nuisances. Use an eco-friendly cleaner whenever possible to protect your home’s environment and the health of any surrounding plant life.
The right protection is another critical aspect. Ensure that your cedar siding is properly sealed or stained to withstand various elements. This proactive maintenance will not only preserve its aesthetic beauty but also extend its lifespan, saving you costly repairs and replacements down the line.
