How to remove Soy Sauce from Outdoor Cushion Fabric
First 60 seconds
Do not reach for a rag and start scrubbing yet. Blot — do not wipe the soy sauce from the outdoor cushion fabric, working from the outside edge of the stain inward so it cannot spread any further. Fermented soy contains both salt and dark caramel-like pigment that stains fast, and woven to resist water and mildew, so it tolerates a more thorough rinse than indoor upholstery.
What you'll need
- Cold water
- Dish soap
- White vinegar
- Hydrogen peroxide (3%)
Step by step
- Gather your materials before you start — set out everything so you are not searching mid-treatment.
- Cold water: flush or blot with cold water — never warm.
- Dish soap: mix a few drops with cold water into a light suds.
- White vinegar: mix one part vinegar with two parts water.
- Hydrogen peroxide (3%): dab on 3% hydrogen peroxide after a patch test.
- Rinse and blot dry with a clean cloth, then press with dry towels and change them until no more transfers onto the towel.
Do not do this
- Hot or warm water. Heat cooks the stain into the fibers, making it permanent.
- Rubbing the spot. It pushes the stain deeper and spreads it outward.
Common questions
Can I use hot water to remove soy sauce from outdoor cushion fabric?
No. Heat sets this type of stain permanently, so always start with cold water and check the surface stays cool throughout treatment.
Is it safe to scrub the stain out?
Scrubbing usually makes things worse. Blot or lift instead of rubbing, working from the outer edge inward so the stain does not spread.
What if the soy sauce stain has already dried?
A dried stain takes longer and may need repeated treatments, but the same agents still work — just re-wet the area gently first to reactivate the stain before treating it.
