Urine stains, whether from a pet or child, penetrate the carpet and get into the pad. Acting quickly prevents the stains from soaking in too deeply and makes removal more effective. Pets are sometimes drawn back to an area to urinate again if any odor remains, so a thorough cleaning requires both stain and odor removal. You can usually remove fresh stains completely, but traces of old stains might remain if they have set too long.
Blot up fresh urine stains with paper towels immediately. Press on the stain to absorb the urine, replacing the towels when necessary. Avoid rubbing because this only spreads the stain.
Fold an old towel in half and set it on top the stain. Stand on the towel or place a heavy weight on top to soak up the remaining moisture in the stain.
Mix three or four drops of liquid dish detergent with 1 cup of warm water. Pour the mixture onto the stain to saturate it and let it soak for one hour.
Blot up the cleaning solution with a clean towel. Wet a sponge with clear water and blot up the remaining detergent residue, wetting the sponge as needed.
Cover the stain with a clean towel. Set a heavy object on top and leave it overnight to soak up the remaining moisture.
Combine equal parts vinegar and water if the odor persists. Blot the stain with the vinegar solution and allow it to air dry to eliminate the odor. For cat urine, use an enzyme cleaner. Follow the cleaner application instructions because these vary by brand.
