How To Clean Plastic Outdoor Furniture Covers

Plastic outdoor furniture covers are essential for protecting investments in patio furniture. These covers shield furniture from the elements, including rain, sun, snow, and wind, extending the lifespan of chairs, tables, sofas, and other outdoor seating arrangements. However, exposure to these same elements also means that plastic furniture covers themselves become dirty, stained, and susceptible to mold and mildew growth. Regular cleaning is crucial to maintaining the effectiveness and appearance of these protective coverings. This article provides a detailed guide on how to effectively clean plastic outdoor furniture covers, ensuring they continue to provide optimal protection for valuable outdoor furniture.

The frequency with which plastic outdoor furniture covers require cleaning depends on several factors, including the local climate, the amount of pollution in the area, and the presence of trees and plants nearby. In areas with high rainfall or humidity, mold and mildew growth can be a significant concern, necessitating more frequent cleaning. Similarly, regions with high levels of air pollution or pollen may require more regular maintenance to prevent the buildup of dirt and grime. As a general guideline, it is recommended to clean plastic outdoor furniture covers at least two to three times per year, typically at the beginning and end of the outdoor season, as well as midway through if significant dirt or staining is observed.

Prior to beginning any cleaning process, it is necessary to gather the appropriate supplies and tools. These will vary depending on the severity of the dirt and staining, but generally include the following: a soft-bristled brush or sponge, a bucket, mild dish soap or a specialized outdoor cleaner, a garden hose with a spray nozzle, a dry cloth or towel, and optionally, a mold and mildew remover. For stubborn stains or mold growth, a diluted bleach solution may be necessary, but it should be used with caution to avoid damaging the plastic material. It is also advisable to wear gloves to protect hands from cleaning solutions and potential irritants.

Key Point 1: Preparation and Initial Cleaning Steps

The first step in cleaning plastic outdoor furniture covers is to prepare the area and the covers themselves. Choose a location that allows for ample space to work and that is suitable for getting wet, such as a driveway, patio, or lawn. Remove the covers from the furniture and lay them out flat, preferably on a clean surface, to facilitate thorough cleaning. Inspect the covers for any tears or damage, as these may require repair before proceeding with the cleaning process.

Begin by removing any loose debris from the covers, such as leaves, twigs, or dirt. A simple sweeping motion with a broom or brush can effectively remove this surface debris. Next, use a garden hose with a spray nozzle to rinse the covers thoroughly. This initial rinsing will help to loosen any remaining dirt and grime, making it easier to remove with soap and water. Ensure that all areas of the cover are thoroughly wetted, paying particular attention to areas that are heavily soiled or stained.

After rinsing, prepare a cleaning solution by mixing mild dish soap or a specialized outdoor cleaner with water in a bucket. Follow the manufacturer's instructions for the appropriate dilution ratio. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic material and shorten the lifespan of the covers. Once the cleaning solution is prepared, use a soft-bristled brush or sponge to apply it to the covers. Gently scrub the entire surface of the covers, paying particular attention to areas that are stained or heavily soiled. Use a circular motion to lift dirt and grime from the surface. For areas with stubborn stains, allow the cleaning solution to sit for a few minutes before scrubbing again.

After scrubbing, thoroughly rinse the covers with a garden hose to remove all traces of the cleaning solution. Ensure that no soap residue remains, as this can attract dirt and promote mold growth. Inspect the covers carefully to ensure that all areas have been thoroughly cleaned and rinsed. If necessary, repeat the scrubbing and rinsing process for particularly stubborn stains or areas of heavy soiling.

Key Point 2: Addressing Mold and Mildew

Mold and mildew growth is a common problem with plastic outdoor furniture covers, especially in humid climates. Mold and mildew not only detract from the appearance of the covers but can also damage the plastic material and pose health risks. Therefore, addressing mold and mildew is a crucial aspect of cleaning plastic outdoor furniture covers.

If mold or mildew is present, a diluted bleach solution can be used to effectively kill and remove these organisms. However, it is essential to use bleach with caution and to follow proper safety precautions. Wear gloves and eye protection to prevent skin and eye irritation. Mix one part bleach with ten parts water in a bucket. Apply the bleach solution to the affected areas using a sponge or brush. Allow the solution to sit for approximately 10-15 minutes to kill the mold and mildew.

After allowing the bleach solution to sit, thoroughly rinse the covers with a garden hose to remove all traces of the bleach. Ensure that no bleach residue remains, as this can weaken the plastic material and cause discoloration. If the mold or mildew is particularly stubborn, it may be necessary to repeat the bleach treatment. Alternatively, specialized mold and mildew removers are available that are specifically designed for use on plastic surfaces. These products are often less harsh than bleach and may be a safer alternative for delicate or colored plastic covers. Follow the manufacturer's instructions carefully when using any mold and mildew remover.

After removing the mold and mildew, it is important to take steps to prevent future growth. Ensure that the covers are thoroughly dried before storing them. Consider using a dehumidifier in the storage area to reduce humidity levels. Regularly inspect the covers for signs of mold or mildew growth and address any issues promptly. In addition, consider using a mold and mildew resistant treatment on the covers to provide ongoing protection.

Key Point 3: Drying and Storage

Proper drying and storage are essential for maintaining the condition of plastic outdoor furniture covers and preventing mold and mildew growth. After cleaning and rinsing, allow the covers to air dry completely before storing them. This can be done by hanging the covers on a clothesline or laying them flat on a clean surface in a well-ventilated area. Avoid placing the covers in direct sunlight, as this can cause the plastic material to fade or become brittle. Turn the covers periodically to ensure that all areas are evenly exposed to air.

To expedite the drying process, use a clean, dry cloth or towel to wipe down the covers. This will help to remove excess water and speed up the drying time. Ensure that all areas of the cover are thoroughly dried, including seams and folds. Once the covers are completely dry, inspect them for any remaining dirt or stains. If necessary, repeat the cleaning process to address any lingering issues.

When storing plastic outdoor furniture covers, choose a cool, dry, and well-ventilated location. Avoid storing the covers in damp or humid areas, as this can promote mold and mildew growth. Fold the covers neatly and store them in a plastic container or bag to protect them from dust and pests. Consider adding a desiccant pack to the container to absorb any excess moisture. Label the container clearly so that the covers can be easily identified when needed. Store the container in a location that is easily accessible but protected from direct sunlight and extreme temperatures.

Regular cleaning, proper drying, and careful storage are essential for maintaining the condition of plastic outdoor furniture covers and ensuring that they continue to provide optimal protection for valuable outdoor furniture. By following the steps outlined in this article, individuals can effectively clean and care for their plastic furniture covers, extending their lifespan and preserving their appearance.

In addition to the methods described above, there are a few other tips that can help to keep plastic outdoor furniture covers clean and in good condition. Avoid placing sharp objects on or near the covers, as these can cause tears or punctures. Avoid dragging the covers across rough surfaces, as this can damage the plastic material. Regularly inspect the covers for any signs of wear and tear and repair any damage promptly. By following these simple tips, individuals can maximize the lifespan and effectiveness of their plastic outdoor furniture covers.

Ultimately, the investment in time and effort required to properly clean and care for plastic outdoor furniture covers is well worth it, as it helps to protect valuable outdoor furniture from the elements and ensures that the covers remain in good condition for years to come. Proper maintenance not only extends the lifespan of the covers but also enhances the overall appearance of the outdoor living space.
