How to Get Cat Urine Smell Out of Clothes
If you want to get the smell of cat urine out of your clothes, start by blotting any excess liquid with a paper towel, then rinse the garment for a few minutes under cool, running water. Next, fill your sink with warm water and add a scoop of oxygen bleach to pre-treat the stain. Leave colored clothing to soak in the sink for at least 1 hour, and let white clothing soak for up to 4 hours. After your clothes have soaked, throw them into your washing machine and coat them in a solution that is 1 part white vinegar and 3 parts water. Finally, run your washing machine on a cool or cold setting and hang up your clothes to air dry once the wash cycle ends.
Sop up excess liquid with a cloth or paper towels. Just blot. If you rub the stain, you could lock it into the clothing. Do this if your cat has just urinated on the clothes. You'll have a better chance of removing the smell on the first wash if you can do it while the stain is fresh. Rinse the spot. Take the affected garment to the sink. Run a stream of cool water over the stain for a few minutes. Blot the stained area dry. Pre-treat the stain with oxygen bleach. Fill a sink with warm water. Add a scoop of oxygen bleach. Place the clothing in the sink. If the clothing is colored, allow it to sit for at least one hour. If it's white, soak it for up to four hours. This product may be sold as Oxiclean, Vanish, or simply oxygen bleach. Avoid using chlorine bleach. When it combines with the ammonia in urine, it can create harmful gases. Mix one part vinegar and three parts water. Vinegar is an acidic product that neutralizes the alkalinity of the urine. Either white vinegar or cider vinegar will work on colored clothing. Use only white vinegar on white garments to avoid staining. Prepare the wash. Throw the garment in the washing machine. Coat it with the vinegar solution. It's safe to add the rest of the laundry to the cycle, if you like. Just avoid a full load so that the soiled garment can get as clean as possible. Use a cool or cold setting. Warm or hot water could set in the urine odor. Add baking soda, if desired. One cup (236.6 g) will do the trick. Thoroughly cover the affected garment before you start the wash. Baking soda will work with the vinegar to neutralize and absorb the urine odor. Air dry the garment. This process could take three hours if you're air drying outside. In an indoor setting, it could take 24 to 36 hours. When the garment is completely dry, do a sniff test to check if the urine odor is gone. If it is, you can wear it as you normally would. If not, re-wash it with an enzymatic detergent. Never use a clothes dryer. The heat could lock in the urine stain and odor for good and ruin your garment. Purchase an enzyme-based detergent. Most detergents labeled as cold-water detergents contain enzymes. However, you should read the ingredients just to be sure. Enzymes allow detergents to fight stains at a much lower temperature than traditional detergents. If possible, choose a detergent that lists protease as an active enzyme ingredient. It's the best at removing urine stains. Make sure to choose a color-safe detergent to avoid bleaching your colored clothing. Run the garment through the laundry. Set the washing machine to a cool or cold water cycle. You may add similar-colored clothing according to package directions. Make the load a little lighter so that there is enough space for the washing machine to clean the clothing thoroughly. Air-dry the clothing. Avoid using a clothes dryer, as the heat might lock in the urine smell. Drying time won't take as long in an outdoor setting. When the garment is completely dry, check it for a lingering odor. If the odor is gone, you can wear your garment as usual. If not, repeat the washing process one more time.
