White mold on vinyl outdoor furniture is a common problem caused by moisture, humidity, and lack of sunlight. It appears as a fuzzy or powdery white substance and can be unsightly and potentially harmful if left untreated. Fortunately, you can remove it effectively with simple, non-toxic methods. Here’s a step-by-step guide.
First, prepare a cleaning solution. A mixture of equal parts white vinegar and water is highly effective for killing mold. Alternatively, you can use a solution of one part bleach to four parts water for more stubborn cases, but test it on a small, hidden area first to ensure it doesn't discolor the vinyl. For a gentler approach, create a paste using baking soda and water.
Next, apply the solution. Put on gloves for protection. Spray the vinegar solution or bleach mixture generously over the affected areas, ensuring complete coverage. If using the baking soda paste, spread it directly onto the mold spots. Let the solution sit for 10-15 minutes to penetrate and break down the mold.
Then, scrub the surface. Use a soft-bristled brush, like a nylon scrub brush, to gently scrub the vinyl. Avoid abrasive tools like steel wool or hard brushes, as they can scratch and damage the furniture. Scrub in a circular motion to lift the mold away.
After scrubbing, rinse thoroughly. Use a garden hose with a spray nozzle to wash away all the cleaning solution and mold residue. Ensure no cleaner is left behind, as it could attract more dirt.
Finally, allow the furniture to dry completely in the sun. To prevent mold from returning, keep your furniture clean by wiping it down regularly. Store cushions in a dry place and consider using a vinyl protectant spray. If possible, cover your furniture with breathable, waterproof covers when not in use for long periods.
