How To Get Urine Smell Out Of Clothes?

I know this is a tough problem....and your extremely aware of the smell.
The only thing you can do is keep cleaning with deodorizers and Lysol.  Bleach is the best but you can't put it on every thing.  One thing I do is put the soiled linens out side till I'm ready to wash them.  You can put them in a large garbage can with a lid out back.

We used this  spray called Totally Toddler Nursery Stain & Odor Remover.  You can get it at Wal-Mart in the Baby department. 

I have to give my wife credit on this on, I'm just an old construction guy.  She said to try peroxide.  Good luck.

I would use javex. If your clothes are colour you can buy bleach for the unbleachables.
Hot water with vinegar will also do the trick.
