                                                          Depends what it's in. If its fabric, I swear by Febreze, however if it is really embedded, a professional steam cleaning is really your only recourse. Urine is hard to get out if it has really taken root. If this is deep into a mattress, even a pro steam cleaning may not do it,it can stink bad in humid weather.
