It is not recommended to use essential oils, parsley juice, coffee and other popular means: they only interrupt the smell for a while, but it becomes much more difficult to get rid of it later. It is better to apply a solution of potassium permanganate to the stain, and when the sofa is dry, check if the smell remains, and repeat the procedure if necessary. Potassium permanganate will not only clean the fabric, but also disinfect it.
Another effective option is to use lemon juice. Soak a sponge in it and wipe the stain thoroughly. Removing the smell will take about 7-10 minutes and 1-2 lemons, but as a result, a pleasant aroma will appear, and the smell of urine will disappear. In addition to this method, there is a wonderful bonus: many cats do not tolerate the smell of citrus fruits very badly, therefore, most likely, at first, your pet will bypass the sofa and try to relieve a small need in another place.
Additional ways to remove unpleasant odor
If the previous options did not work for you for one reason or another, try using laundry soap to clean the sofa. It will help remove the smell, although after that, its own special scent will appear for a while. Other options are vodka, rubbing alcohol, and mouthwash. All of these products, including soap, will disinfect the fabric and remove odors. In addition, many of them dry out rather quickly.
If home remedies have failed, two options remain. Firstly, you can purchase a special product to eliminate unpleasant odors from the sofa, taking into account the peculiarities of the upholstery fabric. Secondly, it makes sense to buy a liquid from the pet store that is designed to get rid of the smell of cat urine.
