Before spot bleaching, test the fabric in a small spot for bleach sensitivity to ensure that the bleach will not damage the fabric.
Add water to the safe bleach powder to create a thick bleach solution. Prepare a glass of cool water, a glass of hot water, two cotton swabs, household ammonia, white distilled vinegar and a clean white towel for the process.
Place the fabric on a dry, clean white towel. Wet the stain, and use the cotton swab to apply bleach solution to the entire stain. Dip the cotton swab in hot water, and apply it to the stain. Next, dip a cotton swab in ammonia, and apply it to the stained area. Repeat the application of hot water with cotton swabs to speed up the chemical reaction, then rinse the stained area with cool water.
Neutralize the bleached area with vinegar, then rinse the area with water.
If necessary, repeat the entire process until the stain is removed.
