I think that putting a lime on urine will only make the smell worse. Use pinesol or a good cleaner that will disinfect also so that you do not get sick.
Lime may help cover the odor of dog urine, however, if you need a product for inside you home I don't know if lime would be my first choice. There are tons of products on the market made for use in your home.
Lime is for urine odors outside. If you have indoor urine odor try vinegar. A 3:1 solution of warm water and vinegar works well. But don't forget to open a window - vinegar is strong.
