Stain Removal
How to remove soy sauce stains
Soy sauce stains combine dark color, salt, and liquid that can spread quickly through fabric. Dilute from the back and treat pigment before heat dries it in.
Quick answer
Blot soy sauce, flush with cool water from the back, pretreat with liquid detergent, wash by the care label, and air dry before checking for a brown shadow.
Never mix bleach with ammonia, vinegar, rust remover, or other cleaners. Test a hidden seam first. Use professional cleaning for valuable, delicate, wool, silk, leather, or dry-clean-only items.
Stain-specific decision points
First action: Blot without rubbing, especially on light fabric.
Heat warning: Do not use heat before the brown shadow is gone.
Fabric limit: White cotton may show a faint ring after the first wash; repeat gentle treatment before drying.

Fabric notes
FAQ
Can soy sauce stain permanently?
It can if heat sets the pigment or if the fabric dye limits treatment options.
Should I use detergent or bleach first?
Use detergent first. Bleach is only for label-approved items and should never be mixed with other cleaners.
Why rinse from the back?
Back-rinsing helps push the dark liquid out of the fabric instead of driving it farther through.
