How to Clean Patio Cushions with Mildew?
Most mildew on patio cushions is a common issue, particularly in humid or rainy climates. If not addressed, it can lead to foul odors, lingering stains, and even weaken the upholstery. The good news is that the best methods make cleaning mildew off patio cushions a cinch. In this guide, we will walk you through step-by-step instructions on how to remove mildew and keep your cushions fresh and clean.
Why Do Patio Cushions Mildew?
Milder thrives in warm, moist environments. Outdoor cushions are especially prone to this condition due to moisture, humidity, and lack of airflow. Factors that contribute to mildew growth include:
- Rain or drinks accidentally soaking into the fabric
- High humidity levels
- Lack of sunlight exposure
- Poor air circulation
- Dirt, stigma, and organic debris are collecting on the cushions
Learn what causes mildew so you can prevent it from growing in the first place and keep your outdoor furniture looking fabulous.
What You’ll Need to Remove Mildew From Patio Cushions
Before you begin, prepare the following supplies:
✔️ Brush with soft bristles or a sponge
✔️ Liquid soap, like mild dish soap or laundry detergent
✔️ White vinegar (for all-natural cleaning)
✔️ Baking soda (for added scrubbing power)
✔️ Borax (for tough mildew stains)
✔️ Hydrogen peroxide (for very deep stains)
✔️ Bucket of warm water
✔️ Spray bottle
✔️ Garden hose
✔️ Microfiber cloth or towel
✔️ Sunlight for drying
How to Clean Mildew from Patio Cushions in 7 Steps
Step 1: Shake Off Loose Dirt and Debris
Before you even start applying any cleaning solution, use a dry brush or vacuum cleaner to remove dust, dirt, and loose mildew spores. This helps prevent it from spreading mildew during cleaning.
Step 2: Make a cleaning solution
Select one of these solutions based on the severity of mildew:
- Light Cleaning: Combine 1 teaspoon of dish soap and 1 quart of warm water in a spray bottle.
- Natural Cleaning: Mix one part white vinegar with one part warm water.
- For Heavy-Duty Cleaners: Combine 1 tablespoon of borax, 1 teaspoon of dish soap, and 1 quart of warm water.
Step 3: Apply the Solution
Generously spray the cleaning solution onto the mildew-affected areas. Allow it to soak for 10–15 minutes to penetrate the mildew and stains.
Step 4: Scrub the Cushions
Take a soft-bristle brush or sponge and scrub the fabric lightly in circular motions. Only use a small amount of force, as this could damage the fabric. If stains remain, dust the area with baking soda and keep scrubbing.
Step 5: Rinse Thoroughly
Wash the cleaning solution completely off with a garden hose. Ensure no trace of soap remains, as it can trap dirt and lead to more mildew growth.
Step 6: Dry in Sunlight
Let the cushions dry thoroughly in the direct sunlight. Sunlight kills mildew and inhibits regrowth. Let both sides of the cushion dry thoroughly before putting them back on the furniture.
