Pet urine can emit a strong odor that can overpower a large area, making the home smell unclean. There are a few products on the market that will mask or remove the odor, but these are mostly chemically-based items that come with a high price tag. Instead, find a home remedy that works for you.
Baking soda works as a natural deodorizing agent that costs only a few dollars per box, and is highly effective in eliminating pet odor. If you know where the smell is coming from, cover the area with a thick layer of baking soda and let sit overnight. If the odor has taken over a room and you cannot figure out where the odor has come from, cover the room's floor with a sprinkling of baking soda, including furniture and other areas that may have come into contact with pet urine. Let sit for a few hours, then vacuum to collect all of the baking soda. This will eliminate the odor, leaving the room smelling fresh and clean.
Vinegar is a natural disinfectant and deodorizer that will break apart the ammonia found in pet urine, and also destroy the odor caused by the urine. If you know where the pet urine stain is, drench with distilled white vinegar, let sit for a few minutes, then scrub into the area with a brush or cloth. If you are unsure where the pet urine stain is located, mix a sprayable solution of 1 cup white vinegar and 2 cups water in a spray bottle. Spray around the home, covering floors, upholstery, and other fabrics.
You can even make a cleaning solution for most floors by mixing 1 gallon of water and one cup of white vinegar in a bucket. Dip a mop in the solution, wring out excess water, and mop over hardwood, laminate, linoleum, or vinyl floors to remove any odor. The vinegar will kill any bacteria and remove the odor caused by the pet urine.
For a citrus-scented deodorizer, mix 2 cups of water in a spray bottle with 1/2 cup lemon juice and 1/2 cup baking soda. Spray onto carpets, upholstery, and other fabrics that may have come into contact with the pet urine, and you will have a citrus-fresh scent that has a slight acidic quality, perfect for eliminating the pet urine smell.
