Blot the stain
Protect your hands with rubber gloves, dampen a cloth with sodium thiosulfate and blot the stain with the damp cloth. Blot from the edges toward the center to avoid spreading the stain. Rub the stain for up to five minutes depending on how long the stain has been on the fabric, and rinse the spot with cold water.
Apply distilled white vinegar
Blot the stain with a clean white cloth soaked with distilled white vinegar until the stain is entirely saturated, and rinse the stain with cold water. If needed, repeat the process until the stain is completely gone. Take caution not to apply excessive vinegar to avoid damaging the fabric. Finally, air-dry the fabric for about six hours to eliminate the stain remnants from the fabric.
Apply a permanent marker if needed
For stubborn yellow bleach stains, cover the stain with a matching permanent marker. Alternatively, remove the color from the whole fabric with sodium hydrosulfite, and dye the fabric with a new color.
