Cleaning an outdoor cushion with a soft brush and soapy water

Quick answer: Brush off loose dirt, clean with mild soap and lukewarm water and a soft brush, rinse well and let the cushion air dry. Sunbrella covers can also be machine washed on a gentle cycle. For stubborn mould, follow Sunbrella's own care guide for a diluted cleaning solution.

Sunbrella resists mould and stains, but in damp British weather dirt and leaves left on the fabric can still give mould a foothold. Regular light cleaning keeps cushions looking new.

Everyday care

  • Brush off leaves, pollen and dirt before they settle in.
  • Blot spills straight away with a clean cloth.
  • Stand cushions on their edge after rain so they drain and dry.

Spot cleaning

  1. Mix a little mild soap in lukewarm water.
  2. Clean with a soft brush or sponge.
  3. Rinse thoroughly to remove all the soap.
  4. Air dry, out of direct heat.

Machine washing covers

Unzip the covers and wash them on a gentle cycle with mild detergent. Air dry rather than tumble dry, and put the covers back on while still slightly damp so they ease back into shape.

Mould

Mould grows on dirt and moisture, not on the fibre itself. Clean the area, then follow Sunbrella's care guide for its recommended diluted solution for stubborn mould, rinse very thoroughly and dry fully. If the foam inside smells musty, replace the foam; our guide on replacing foam or covers explains how to tell.

Winter storage

  • Clean and dry cushions fully before storing them.
  • Store somewhere dry and ventilated, not sealed in plastic.
  • Stand them on edge rather than stacking them flat.

Frequently asked questions

Can I put Sunbrella covers in the washing machine?

Yes, on a gentle cycle with mild detergent. Air dry them.

Why do Sunbrella cushions still get mould?

Mould feeds on dirt and moisture sitting on the fabric or in the foam. Regular cleaning and quick-drain foam prevent most of it.

Can I use a pressure washer?

It is better not to; a soft brush and gentle rinse are kinder to the fabric and stitching.
