My cat is very well conditioned, leash trained etc but one day about four months ago he was in my sons BMW a little too long, we were out all day and he ONLY uses his litter box. I walked him outside several times but he just doesn't get that he can relieve himself wherever outside. Any while I was in a store, he took a pi$$ on the carpet in the drives footwell. Now I don't know what it is about cat urine but it's RANK
So heres what I've tried:
Shampoed and used my shop vac to suck up the soapy water, used like a quart of hot soapy (laundry detergent, also rug shampoo for 'pet stains'), done that 4X and ran as fan into the car for 2 days between each session to dry the carpet.
Soaked and resoaked using a spray on pet odor remover, fan in window for 2 weeks strait.
110 volt Ozone generator, bought it off ebay for like $89. left it plugged in overnight a couple times. Seemed to help but odor returned. Problem I've heard is that the Ozone with breakdown(disintegrate?) all the platics in the car so I don't want to overdue it.
The odor is 10% of what it was(still 9.99% too much!) but its still noticeable on hot days when car is closed up and in the sun. So now that you mentioned the absorbant nature of plastic DJD, I'm wondering if the carpet isn't the culprit but the plastics? I keep a bottle of Febreeze in the back seat floorboard and use it all the time on the carpet, I wonder if I should mist the leather seats and the plastic dash parts?
