Combine one cup of white vinegar and three cups of water in a mixing bowl (1:3). Allow the urine-stained object to soak in this solution for a few minutes. If desired, cover the affected area with baking soda. Baking soda, in conjunction with vinegar, will absorb and neutralize smells. Let sit for at least 30 minutes before washing as normal.
If you have several items that need cleaning, divide the mixture between them. This way you won't need to clean out the whole bowl after each use.

Urine stains that are new:
Soak up as much pee from the upholstery as you can. Sprinkle baking soda liberally over the stain and leave it for 5 minutes. The baking soda will aid in the deodorization of the stain. Combine equal parts water and distilled white vinegar in a spray bottle or other container. Spray the mixture on the spot regularly until it is completely removed.
The best cleaning method for old cat urine is a combination of blotting and washing. Use a clean, soft cloth to gently blot away any excess liquid before washing the area thoroughly with a gentle cleaner. If possible, choose an acid-based product since ammonia and other substances found in cat urine are alkaline.
If you don't remove the smell entirely, then consider replacing the furniture or carpeting. These products are made to hide unpleasant smells, so if they can't disguise them then perhaps your choice of seating isn't right for your home environment.
Create a solution of baking soda, peroxide, and any dish detergent of your choice. The mixture of the three is frequently strong enough to take away even the worst pee odors. Combine 8 fluid ounces peroxide, 3 tablespoons baking soda, and a few drops dish detergent in a mixing bowl. Stir well and allow to sit for at least 30 minutes but no more than 2 hours.
After 30 minutes have passed, stir the mixture again. Put a small amount of it on a piece of paper towel and let it dry in the sun if you can. If it still smells like pee after half an hour, repeat the process with another portion of the mix.
You should only need to do this step once. From then on, simply spray some more peroxide on the toilet brush and wash it under hot water until it's clean.
This method has two advantages over using disinfectant sprays or tablets: firstly, it doesn't contain any chemicals that could harm children or pets; secondly, it works quickly - usually within an hour or so of putting out the peed upon.
If you want to make sure there are no remaining bacteria after using this method, pour a little bit of the mixture into a bowl of water and see what happens. If it gets cloudy with the baking soda, there's still poopie behind.
Vinegar is an acid that reacts with the alkaline ions that accumulate in dried urine stains to neutralize them. Apply a solution of one part water to one part vinegar to walls and hard flooring. You may also add a pinch of baking soda to increase the solution's effectiveness to eradicate smells. Let it sit for a few minutes, then wash with a gentle cleaner.
If you have carpet, mix 1/4 cup vinegar with 2 cups hot water. Submerge the stained area for about 10 minutes, then rinse well with fresh water. Repeat as needed.
You can also use club soda instead of water. Just make sure to get the unscented kind because they tend to be more effective at removing odor-causing chemicals from your carpet.
Finally, you can use lemons or lime juice as a natural deodorizer. This works best on older stains that no longer smell like lemon or lime since the acidity level has changed.
These are just some of the many ways you can keep your home smelling nice without using chemicals.
