Greetings!

Recently we bought a bunch of pre-owned vehicles from a car auction. We are doing complete interior and interior detailing of these vehicles. They are almost in good condition, but few of them have cat urine smell. We have washed the rugs with detergents and sprayed the vinegar, but smell is still there. Now, we also cleaned the sea thoroughly. 

However, vehicles are still smelling bad. Now, I decided to spray cat urine odour remover from here https://ourfitpets.com/care/best-cat-urine-odor-removers/. Can you please suggest a good one that works well for cars? You can also share if you have some other ideas about the removal of this kind of odours. 

Waiting for your kind suggestions.
