For your clothes, wash them in about 1/4 cup of apple cider vinegar along with your regular detergent. It takes out the urine odor. It works best if the urine is still wet.
We've got a cat who apparently decided that the laundry basket looked like a litter box :shock: and we had to do something QUICKLY a few days ago when an accident happened. The apple cider vinegar worked like a charm. Whew. :)
