How to Clean Outdoor Cushions (Mildew and Stains)

Outdoor cushions face rain, sun, pollen, bird droppings and mildew. Cleaning them a few times a season keeps them looking good and lasting longer.

Check the Care Label

Many cushion covers are removable and machine-washable. Follow the label if it has one.

What You'll Need

A vacuum or soft brush
Dish soap
Oxygen bleach (for mildew)
A soft-bristle brush
A garden hose
A bucket

Step 1: Brush Off Debris

Brush off leaves, dirt and pollen, or vacuum the cushions.

Step 2: Make a Cleaning Solution

Mix 1 tablespoon of dish soap in a bucket of warm water. For mildew, add oxygen bleach according to the package directions.

Step 3: Scrub

Dip the brush in the solution and scrub the cushions, including seams and corners. Let the solution sit for 15 minutes on mildew spots.

Step 4: Rinse Thoroughly

Rinse with a hose until no suds remain. Leftover soap attracts dirt.

Step 5: Dry Completely

Stand cushions on their sides in the sun so water drains out. Flip them during drying. Make sure they're completely dry inside before storing to prevent mildew.

Protect Your Cushions

Use a fabric protector spray made for outdoor fabric.
Store cushions in a deck box or bring them inside during rain.
Shake off debris regularly.
