Removing urine from carpets and mattresses is not very difficult. Urine contains salts and when they are on the mattress they smell. The smell of the urine won’t go away quickly. It will stay in the air for some days or weeks. Even if you put the mattress in sunlight for drying, the smell won’t go away.
Urine contains bacteria and if urine is left on the mattress for many hours or days molds or fungus could form and spoil the mattress completely. You need to take care of your mattress and try to remove the urine stains as quickly as possible.
During the rainy season the urine in the mattress along with the humidity in the air makes the smell worse. Spraying deodorants won’t make the smell go away from the mattress. You need to clean the urine from inside the mattress so that they don’t smell, and not only from the upper part of the mattress.
There are many ways for people to remove the urine from the mattress. Some people pour vinegar on the mattress and suction it with a vacuum machine. Putting alcohol on the urinated area is another idea. Some people put shampoo on the mattress and clean it and dry the mattresses in the sun.
