When a dog urinates on the carpet, the best way to remove it is to act while the stain is still wet. Unfortunately, this is not always possible, especially if you are out of the house when the accident occurs. Dried dog urine stains are much more difficult to get out of carpet, especially if the stain is older or if the dog repeatedly urinates in the same spot. Urine-saturated carpet often leads to costly repairs and replacements. Before throwing out your urine-stained carpet, try cleaning it using a natural method.
Pour enough clean water onto the dried dog urine to saturate and dilute the stain. Extract the liquid using a wet-vac or old towels.
Sprinkle a handful of baking soda directly onto the stain.
Mix together 1/2 cup 3 percent hydrogen peroxide and 1 teaspoon clear dish soap. Pour the mixture on top of the baking soda and work it into the carpet using a soft scrubbing brush or your fingers. Wear rubber gloves to protect your hands from the hydrogen peroxide.
Leave the mixture to dry overnight, and vacuum over the stain once dry to remove. Repeat the process if the stain or odor remains.
