You can remove stubborn stains from upholstery and carpeting by making a spot-cleaner with oxygen bleach powder (such as OxiClean).
It’s easy! Just mix one tablespoon of oxygen bleach with one cup of hot water. Stir well until the oxygen bleach powder is completed dissolved.
Next, dip a toothbrush into the spot cleaner mixture and scrub the stain.
Repeat these steps, keeping the area wet for at least five minutes.
Finally, blot the stained area with paper towels and let dry.
