Whether it's from a puppy that is not housebroken or a toddler going through potty training, yellow urine stains can end up on your carpet. Fortunately, common household ingredients like vinegar and baking soda can take care of both the stain left on the carpet and the accompanying odor. When using a homemade stain remover, remember to always test it on a small portion of the carpet first.
Place several paper towels over the urine stain if it is still fresh. Press down on the paper towels to soak up as much urine as possible.
Pour 1/2 cup white vinegar and 1/2 cup water into a bowl, and mix them together well.
Pour the liquid over the stain.
Work the solution into the stain with a scrubbing brush.
Blot the excess moisture with paper towels.
Pour baking soda onto the stain after the carpet has dried.
Mix 1/2 cup 3 percent hydrogen peroxide and 1 tsp. liquid dishwashing detergent together in a bowl.
Pour the solution on top of the baking soda.
Scrub the solution into the stain with the scrubbing brush.
Allow the carpet to dry.
