How to remove urine stains after a long time?

In life, many people do not pay attention to private hygiene, especially women. After going to the toilet, they don’t think about wiping their private parts with paper towels or wet wipes. As a result, a large amount of urine soaks into the underwear, and over time, many urine stains will appear. In addition, some women are lazy and notice urine stains on their underwear early on, but they don't like to clean them, resulting in more and more urine stains. So, how to remove urine stains after a long time?

1. Acetate, carpet synthetic fiber or wool fiberglass, rayon, silk, triacetate, wool

To remove urine stains, sponge with cold water by moistening a sponge pad and gently wiping from the center of the stain to the outside, or immediately dilute the stain with club soda. Apply some water-based stain remover and a few drops of ammonia to the urine stain. Silk and wool should not be treated with ammonia. Cover the urine stain with an absorbent pad soaked in water-based stain remover. Cover long enough to remove all of the stain.

Once the pad has absorbed the urine stain, it should be replaced. Keep both the absorbent pad and the urine stain moist with a water-based stain remover and ammonia. Then rinse with clean water, that is, through the stain remover, to clean away some of the dye and stain remover residues from the urine stain, and then apply some water-based stain remover and a few drops of white vinegar. Rinse the fabric clean with water and repeat the process as necessary. Finally let dry. When treating carpets, follow all procedures with Stain-X Carpet Stain Remover, Up & Out (not for wool) or Afta Carpet Stain Remover.

2. Acrylic, cotton, linen, modacrylic, nylon, polyolefin fiber, polyester, spandex

Rinse the urine stain immediately with water or club soda. Add 1/2 teaspoon of liquid dishwashing detergent or fabric stain remover and 1 tablespoon of ammonia to about 1 liter of warm water and soak the stained fabric in the mixture for 30 minutes. Next, rinse with water. If the urine stain remains, soak it in a mixture of about 1 liter of warm water and 1 tablespoon of white vinegar for 1 hour.

Be extra cautious when using white vinegar on cotton and linen fabrics. Rinse well with water and let dry. If the urine stain is still there, try applying rubbing alcohol on it and then lightly brushing it. That is, use a brush to lightly brush the surface urine stain on the contaminated wear-resistant fabric or other material. Don't apply pure rubbing alcohol to acrylic or modacrylic—dilute the alcohol to one part with two parts water first. When the urine stain begins to loosen, use an absorbent pad to absorb the liquid and the urine stain. Keep both the absorbent pad and the urine stain moist with alcohol, and replace the pad after it has absorbed the urine stain. Finally, let the fabric dry.
