How To Clean Mold Off Plastic Outdoor Furniture

Mold growth on plastic outdoor furniture is a common problem, particularly in humid climates. Effective cleaning methods can restore the furniture's appearance and prevent further damage. This article outlines various techniques for removing mold and mildew from plastic outdoor furniture.

Essential Cleaning Supplies

Gathering the necessary supplies beforehand streamlines the cleaning process. Commonly used items include:

Garden hose with spray nozzle
Bucket
Soft-bristled brush (e.g., scrub brush, dish brush)
Cleaning solution (options detailed below)
Protective gloves
Safety glasses (optional but recommended)
Old towels or rags

Preparing the Furniture for Cleaning

Proper preparation ensures efficient mold removal and minimizes the spread of spores. These steps include:

Moving the furniture to a well-ventilated area, preferably outdoors.
Rinsing the furniture with a garden hose to remove loose dirt and debris.
Protecting surrounding plants or surfaces by covering them with a tarp or plastic sheet.

Cleaning Solutions for Mold Removal

Several effective cleaning solutions can tackle mold on plastic furniture. Choosing the right one depends on the severity of the mold growth and available resources.

Dish Soap and Water: A mild solution suitable for light mold growth. Mix a few squirts of dish soap with warm water in a bucket.
Vinegar Solution: A natural and effective mold remover. Mix equal parts white vinegar and water in a spray bottle or bucket.
Bleach Solution: A stronger solution for heavy mold infestations. Mix one part bleach with ten parts water in a bucket. Always test this solution on an inconspicuous area first to ensure it doesn't discolor the plastic.
Commercial Mold Cleaners: Various commercial products are specifically formulated for mold removal. Follow the manufacturer's instructions carefully.

Applying the Cleaning Solution

Proper application techniques maximize the effectiveness of the chosen cleaning solution.

Apply the cleaning solution liberally to the affected areas, ensuring complete coverage.
Allow the solution to dwell on the surface for 10-15 minutes to penetrate the mold.
Avoid letting the solution dry completely, particularly in direct sunlight.

Scrubbing the Mold

Scrubbing helps dislodge the mold from the plastic surface. The appropriate scrubbing method depends on the furniture's texture and the severity of the mold.

Use a soft-bristled brush to scrub the moldy areas, applying gentle pressure.
For stubborn mold, use a slightly stiffer brush or a scrubbing pad.
Avoid using abrasive cleaners or tools, which can scratch the plastic surface.

Rinsing and Drying

Thorough rinsing and drying are crucial for preventing mold regrowth.

Rinse the furniture thoroughly with a garden hose, ensuring all traces of the cleaning solution are removed.
Dry the furniture completely with old towels or rags or allow it to air dry in direct sunlight.
Ensure the furniture is completely dry before storing it.

Preventing Future Mold Growth

Taking preventative measures can significantly reduce the likelihood of future mold infestations.

Store furniture in a dry, covered area when not in use.
Regularly clean the furniture with soap and water to remove dirt and debris that can promote mold growth.
Improve air circulation around the furniture by ensuring adequate spacing.
Consider applying a mold-inhibiting spray or sealant to the furniture after cleaning.

Addressing Stubborn Mold Stains

Occasionally, mold can leave behind stains even after thorough cleaning. Several methods can address these residual stains:

Applying a paste of baking soda and water to the stained areas and letting it sit for several hours before scrubbing and rinsing.
Using a specialized plastic cleaner and restorer, following the manufacturer's instructions.
For white plastic furniture, consider using a diluted bleach solution (test in an inconspicuous area first).
