They make special pet urine cleaners that's suppose to have enzymes that dissolve the urine smells.

We'll plan to treat the floor with some type of enzyme that kills bacteria, but I'm also planning to run an ozone machine.Do you have any recommendations of machines you've used and for how long to run them?

After several rounds of the enzyme scrub with a deck brush, letting it sit, and rinsing thoroughly, the smell went away and the floor was good for the LVP. 

Has anyone had success using enzymes products to open drain field lines on a septic.

Fluids should dissipate into the leech field and solids should be in tank where enzymes can eat them .

We tried: 3 different types of enzyme cleaners that had good reviews, water and vinegar, soap, essential oils, lots of scrubbing, cleaned our air ducts, and most recently an odor sealer on the floor that dries clear.

UV flashlights to spot bio materials.use enzyme based products to kill the residue.  

@Csilla VeressShort of converting to PVC, you can try some drain clearing products at Homedepot and Lowes that uses enzymes to remove the build up.

Yes, cat pee is awful, but enzyme treatment, Kilz and an ozone generator will do the trick to eliminate it. 

In a food service setting, the pest control company will often set up an automatic pump to dispense grease-eating enzymes into the trap every day.
