Urine stains on carpet can be frustrating to remove, especially if the stains are old. As the urine soaks down into the fibers of the carpet, removal is more challenging than with fresh stains. Whether from a dog, cat or person, old urine stains on carpet will not only leave an unsightly mark but also an unappealing odor. Removing old urine stains will freshen the look and smell of the carpet.
1. Fill a clean spray bottle with equal parts white vinegar and lukewarm water. Shake the bottle to combine the ingredients.
2. Spray a generous amount of the solution directly onto the urine-stained area of the carpet. Apply enough solution so that the carpet is saturated, allowing it to reach the fibers deep into the carpet.
3. Use a scrub brush to work the mixture into the carpet. Apply force when scrubbing to ensure that it gets far down into the carpet.
4. Allow the mixture to set on the carpet for about 30 minutes. Blot the solution from the carpet using old rags. Allow the carpet to air dry.
5. Sprinkle a liberal amount of baking soda over the affected area of the carpet once it has dried from the vinegar solution.
