How to remove Fish / Fish Oil from Corduroy
First 60 seconds
The first sixty seconds decide how this turns out. Blot — do not wipe the fish / fish oil from the corduroy, working from the outside edge of the stain inward so it cannot spread any further. The oil carries a strong odor that lingers long after the visible mark is gone unless fully rinsed, and the ridged pile crushes flat if pressed hard while wet, so blotting beats scrubbing.
What you'll need
- Cold water
- Dish soap
- White vinegar
Step by step
- Test first: dab your chosen agent on a hidden corner of the corduroy and wait 2–3 minutes to confirm no discoloration.
- 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.
- 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 fish / fish oil from corduroy?
Hot water is not usually necessary, but on corduroy it is safer to stay with cool water regardless, since the ridged pile crushes flat if pressed hard while wet, so blotting beats scrubbing.
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 fish / fish oil 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.
