Overview
Outdoor cushions collect dirt, pollen, mildew, and stains quickly—especially during warm weather. The good news is that you can clean them easily using simple household products. This guide shows you how to deep clean, deodorize, and protect outdoor cushions so they look fresh all season long.
What You’ll Need
- Mild dish soap
- Warm water
- White vinegar
- Baking soda
- Soft scrub brush
- Garden hose
Step 1 — Brush Off Loose Dirt
Use a soft brush to remove dirt, pollen, and debris. If you’re also cleaning nearby patio furniture, see our guide on how to clean outdoor furniture.
Step 2 — Mix a Cleaning Solution
Combine warm water with a few drops of dish soap. For mildew or strong odors, add 1 cup of white vinegar. If you’re dealing with mildew on clothing, see our guide on how to remove mildew smell from clothes.
Step 3 — Scrub the Cushions
Dip the brush into the cleaning solution and scrub the cushions in circular motions. Pay extra attention to stained or heavily soiled areas.
Step 4 — Rinse Thoroughly
Use a garden hose to rinse away soap and residue. Avoid using a pressure washer—it can damage the fabric.
Step 5 — Remove Odors With Baking Soda
Sprinkle baking soda over damp cushions and let it sit for 15–20 minutes. This helps neutralize odors and brighten the fabric. For clothing odors, see our guide on how to remove sour smells from clothes.
Step 6 — Air‑Dry Completely
Stand cushions upright or place them in direct sunlight to dry. Make sure they dry fully to prevent mildew from returning.
Step 7 — Protect the Fabric
Once dry, apply a fabric‑safe outdoor protectant spray to help repel water, dirt, and UV damage.
