Organic stains are tough to remove from fabrics. Success often depends upon getting to work lifting the stain as soon as possible. When egg, an organic substance full of protein, has dried on a carpet or any thick fibrous mat that must stay in place, it is important to remove as much of the substance as possible before again hydrating the stain. Patience and a few extra steps can help lift a dried egg stain from a carpet.
Scrape as much dried egg out of the carpet as possible with a plain-edged table knife or metal spatula. Vacuum frequently to keep small bits of egg yolk from working into the carpet. Vacuum carefully before wetting the carpet.
Add 2 tbsp. of household, non-sudsing ammonia to two to four cups of water in a spray bottle. Saturate the rug with the ammonia. Blot the area with a white cloth, turning it and changing cloths, if necessary, until the stain is gone.
Use a dish soap solution on the stain if the ammonia does not work. Dilute a few drops of dishwashing soap in a quart of water and spray it onto the stain. Blot with clean white cloth or paper towels to work the soap into the carpet and pick up stain. Repeat if the stain is not gone.
Rinse the rug with clear water, spraying and blotting with a thick towel. Wet the area again and dry, covering it with a folded towel or pad made with paper towels weighed down with bricks or some other heavy object.
Check the area after 12 to 24 hours. If the stain persists, spray just the tufts that still hold stain with three percent hydrogen peroxide and allow to stand for one hour before blotting. Repeat until the stain disappears.
