So my barn find that was sitting for 6 years smells of mice urine.
I've opened the car up, removed all seats and cleaned out all the nests in and under the seats and the vents. I've green machined the carpet twice, cleaned every bit of the interior. Removed the underlayment from under the rear bench (which is where the major nests were) and cleaned the floor board under it. Used Odoban all over. Still smells.

Thinking about using an ozone generator and maybe urine b gone.
Thoughts and advice needed!

 

I bought a Vista that reeked w/ urine. I took out seats and actually power washed them outside and inside. Then left seats on a small wagon and brought out on sunny days- in overnight until dry. Still some odor, then bought a type of smell eliminator spray from hardware store and soaked down with that. Then was acceptable but still if car left closed up in hot sun could notice a bit. Later we didn't notice a plastic milk jug was cracked and leaked about a pint in carpet- underlayment on daily driver- That was awful- spoiled milk is the worst. Neighbor let me borrow a ozone machine and it worked but in that case I took out the soaked underlayment- Good luck...

 

you are looking at a new interior .Also repaint floors and seat springs that is the best way to get rid of the smell.

Try Clorox wipes on surfaces that can be wiped.

 

Liberally apply baking soda to the affected areas. Let it sit for a couple of days in open area. Then wash the carpet/interior pieces. Baking soda will absorb the odor and can be purchased in bulk for cheap (check Sam’s).

 

"Natures Miracle" works great on dog and cat urine odor and stains. Soak area, cover with a damp towel for a day.

 

X2..good stuff

 

Have you checked headliner?

 

Don't know that I'd be taking advice on odor remediation from a guy called "Funkwagon"!

X3 on the Nature's Miracle. As a longtime dog owner, I've found this stuff to be invaluable around the house, although I have yet to use it in a car.

 

The bottom section of your rear seat has a molded foam main layer along with burlap and maybe some cotton batting.....all likely holding the odors. Rear seat BACK (upright section) is likely ALL layers of cotton batting....again, probably a huge odor sponge.

Those layers should probably be replaced but it'll cost if you have to pay someone else to do it and your seat covers might be ruined in the process of removing and/or trying to re-install them.

The vinyl seat covers also have foam and fabric on the backside of the covers....presenting yet again another "sponge" for odors.

Virtually all the stuff inside the car will be an odor sponge....less so on the harder plastic pieces like a console or dash assembly.

droldsmorland mentioned the headliner....again, the underside of the metal roof skin may be covered with a sort of thin jute insulating material...yep...another "sponge". If the headliner is removed probably a good idea to scrape all the thin jute layer off. NOTE: If you do remove the headliner and scrape this stuff off the roof underside....wear a respirator (or a tight fitting mask at a minumum) when doing so as the stuff turns into a nasty dust when you start scraping away at it.

Yeah, “Jacksock2000” was already taken!!🙄😅

 

The worst funk I ever smelled was these two middleschoolers at my boarding school who had done no laundry since school started and, once the heat kicked on and stayed on, like December, their room had to be stripped. They lived in a tent in the lobby for a while.

 

May be worth a shot or two.

 

You have to find the nest, remove and then neutralize the smell with some rugged cleaners. You have gotten the usual spots, but there might be more nests. Invest in a cheapo borescope and start looking in all the nooks and crannies. Those little ****** move in everywhere!
