How to Clean and Store Outdoor Cushions Year Round

How to Clean and Store Outdoor Cushions Year Round

Updated October 2025 | by The Cushion Guys

Outdoor cushions go through a lot during the year. From strong UV rays and rain showers to muddy shoes, food spills and everyday garden use, outdoor seating naturally collects dirt and wear much faster than indoor furniture.

Without proper care, outdoor cushion fabrics can fade, foam can lose support and trapped moisture can lead to mould or mildew problems over time. The good news is that a simple cleaning and storage routine can dramatically extend the lifespan of your cushions while keeping your outdoor seating looking fresh and comfortable throughout the seasons.

At The Cushion Guys, we manufacture made-to-measure outdoor cushions, garden sofa cushions and bench cushions designed for everyday outdoor living. This guide explains exactly how to clean, protect and store outdoor cushions correctly so they last longer and continue looking their best year after year.

Why Outdoor Cushion Care Matters

Outdoor cushions are constantly exposed to conditions that gradually break down fabrics, fillings and foam interiors.

Common causes of outdoor cushion damage include:

  • UV rays causing colour fading
  • Rain and trapped moisture leading to mildew
  • Dirt and pollen building up in fabrics
  • Food and drink spills staining cushion covers
  • Bird droppings and tree debris
  • General wear from regular use

Routine maintenance helps protect outdoor fabrics, preserve foam support and keep seating looking cleaner and more inviting throughout the year.

Daily and Weekly Outdoor Cushion Care

Small amounts of regular maintenance make a huge difference over time.

Simple weekly care helps prevent dirt becoming deeply embedded into fabrics and reduces the need for aggressive deep cleaning later.

Outdoor Cushion Cleaning Checklist

  • Shake cushions regularly to remove dust and debris
  • Brush away leaves, crumbs and pet hair using a soft brush
  • Wipe small spills immediately with a damp cloth
  • Allow cushions to air dry after rainfall
  • Vacuum outdoor cushions gently once per week

Quick maintenance routines help outdoor seating stay fresher between seasonal deep cleans.

How to Deep Clean Outdoor Cushions

Even well-maintained outdoor cushions benefit from occasional deep cleaning, particularly after winter storage or periods of heavy use during summer.

Step 1: Prepare a Cleaning Solution

Mix warm water with a mild detergent or outdoor fabric cleaner.

Avoid strong bleach-based products unless the fabric manufacturer specifically recommends them, as harsh chemicals can damage outdoor fabrics and weaken fibres over time.

Step 2: Brush Away Loose Dirt

Before applying water, remove loose dirt and debris using a soft brush or vacuum cleaner.

This prevents dirt rubbing deeper into the fabric during cleaning.

Step 3: Clean the Cushion Surface

Using a cloth or soft brush, gently clean the entire cushion surface with the cleaning solution.

Pay extra attention to:

  • Heavily used seating areas
  • Food or drink stains
  • Edges and seams
  • Areas exposed to tree sap or pollen

Step 4: Rinse Thoroughly

Rinse cushions thoroughly using clean water to remove all detergent residue.

A garden hose works well for this, but avoid pressure washers as they can damage outdoor fabrics and force water deep into the foam.

Step 5: Allow Cushions to Dry Completely

This is one of the most important stages.

Outdoor cushions must dry fully before being reused or stored. Trapped moisture is one of the main causes of mould and mildew.

For best results:

  • Stand cushions upright while drying
  • Allow airflow around all sides
  • Dry cushions outdoors in mild weather
  • Avoid storing cushions while damp

How to Remove Mould and Mildew from Outdoor Cushions

Mould and mildew are common problems for outdoor seating, especially after wet weather or incorrect storage.

If mildew appears:

  • Move cushions outdoors immediately
  • Brush away loose mould spores carefully
  • Clean using warm soapy water and mild detergent
  • Rinse thoroughly with clean water
  • Allow cushions to dry fully in fresh air

For more stubborn mildew stains, specialist outdoor fabric cleaners may be required.

The best long-term solution is prevention through proper drying and storage.

How to Care for Outdoor Cushion Covers

Outdoor cushion covers protect the inner foam and play a major role in how your seating looks and performs over time.

If your covers are removable:

  • Machine wash on a gentle cycle if the care label allows
  • Use mild detergent only
  • Wash at low temperatures
  • Allow covers to air dry naturally

For non-removable cushion covers:

  • Use a damp cloth and mild detergent
  • Clean gently using circular motions
  • Avoid soaking the cushion excessively

Keeping covers clean helps maintain appearance while reducing long-term staining and fabric wear.

Protecting Outdoor Cushions from UV Rays

Strong sunlight is one of the biggest causes of outdoor fabric fading.

Even premium outdoor fabrics gradually lose colour over time if constantly exposed to direct UV rays.

To reduce fading:

  • Rotate cushions regularly
  • Store cushions indoors when not in use
  • Use protective covers during prolonged sunny periods
  • Choose UV-resistant outdoor fabrics

High-quality outdoor fabrics such as Sunbrella are specifically designed to offer better fade resistance and long-term outdoor durability.

Best Outdoor Cushion Fabrics for Durability

The fabric you choose affects how well your outdoor cushions cope with changing weather conditions.

Water-Resistant Outdoor Fabrics

These fabrics help repel light rain and moisture while remaining breathable enough for everyday outdoor use.

UV-Resistant Performance Fabrics

Performance fabrics are designed to resist fading and maintain colour even during prolonged sun exposure.

Heavy Woven Outdoor Fabrics

Woven outdoor fabrics offer strong durability and are ideal for busy gardens and family seating areas.

Outdoor Cushion Foam and Filling Options

The foam inside your outdoor cushions affects comfort, support and how well the cushions handle regular use.

Foam Type Comfort Feel Best For Durability
High-Density Foam Firm and supportive Bench seating and dining furniture Excellent
Medium Comfort Foam Balanced comfort Outdoor sofas and lounge seating Very Good
Foam Wrapped in Fibre Soft with structure Luxury outdoor seating Very Good

Choosing the correct foam helps outdoor cushions remain supportive and comfortable throughout the year.

How to Store Outdoor Cushions During Winter

Proper winter storage dramatically increases the lifespan of outdoor cushions.

Although outdoor fabrics are designed for durability, leaving cushions outdoors throughout winter exposes them to unnecessary moisture, frost and dirt buildup.

Best Places to Store Outdoor Cushions

  • Dry garages
  • Garden storage boxes
  • Sheds
  • Utility rooms
  • Indoor cupboards or airing cupboards

Always ensure cushions are completely dry before storage.

Avoid Sealed Plastic Bags

Plastic bags can trap moisture and encourage mould growth.

Instead, use:

  • Breathable storage bags
  • Fabric storage covers
  • Ventilated storage benches

Airflow is essential for preventing damp and mildew during long-term storage.

Signs Your Outdoor Cushions Need Replacing

Even with proper care, outdoor cushions eventually wear out through years of use and exposure.

Common signs replacement cushions may be needed include:

  • Severe fading
  • Flattened or unsupportive foam
  • Persistent mildew problems
  • Torn or fraying fabric
  • Foam that remains damp internally
  • Loss of shape and comfort

Replacing tired cushions can completely refresh the look and comfort of your outdoor seating area without replacing the furniture itself.
