Old pet stains are harder to remove.

Removing set-in pet stains can be challenging. It's always best to catch pet and other stains as soon as the stain occurs if possible. But if a stain is located in an out of the way place, or if you move into a home with stained carpets, you may need to treat an old, dried stain. A few simple household items will help to remove even old pet stains.


Step 1

Spray the stain with a solution of one cup of water with one tablespoon of vinegar. Blot moisture with paper towel.
