I tried this mixture today. I didn't realize I was using 4x Peroxide purchased from home Depot. I just sprayed it into the cowl area and kept it wet, letting it soak for at least an hour while I did some other things on the car. I just hosed it out and it made a huge difference. The solution with 4x Peroxide was a little harsh and irritated my skin so be careful when ou choose the Peroxide.

Very effective!

 

I picked up my 73 back in September. I knew it had been infested at one point, but was not sure of the totality of the situation. The car had a major restoration in the early 90s, then sat in a one car a garage because the owner developed a disability of some sort and was no longer mobile. This was an L82 (now ZZ4), 4-speed with all the options car. Painted in late 80s as part of the restor, but still looked new after it was rubbed out. It sat, and sat, and sat in that garage. When the folks I got it from found it, it was literally covered in (full) garbage bags and had been so for quite along time. The maggot-induced garbage variety. It was a gagging experience they said. Snake skins were found in a few areas outside the car. The car was filled about 3-4 inches deep with acorns and other nuts that had been eaten. Every single square inch. The guys I bought it from replaced the tank, fuel lines, carb, battery, etc to get it running. They vacuumed out the nuts as best they could. Then I bought it. The mouse and urine was so old, it really no longer smelled like mice. It was just a funky old smell, or so I thought.

The gauge cluster had some strange damage like acid was dripped on it. Should have been my first real big clue. After messing around replacing the entire brake system and going through the mechanicals to ensure everything was good, I looked into the dash. Horrifying. I ended up removing and trashing the entire AC/Heat system (ducts, controls, vents, etc) as they were beyond sensible repair. The damage to the gauges was due to the nest behind the passenger side of the dash and the 20 years worth of mouse urine dripping down the front gauges. The gauge cluster was trash. Lower console was trash. I started pulling every bit of carpet and interior I could get my hands on, bagging it all up and trashing it. They had gotten into every square inch of that car. Even the rear body mount cavities were completely filled with feces and urine sludge. (I found a loaded pistol in the rear drivers side mount cavity all the way in the back. Interesting). UI used the peroxide, baking soda and Dawn mixture as found here and that helped a bunch. Ended up using enzyme cleaner and an ozone machine for the rest of the smell after cleaning. Everything was then encapsulated with Dynamat, aluminum duct tape, and now new carpeting with the rubberized backing (ACC) and jute. Going back together now, and still no side of having gotten the hantavirus. In the end, it is worth it. But oh what a chore. I was lucky to get the nasty part done before it got hot out this summer. Still have to install a few panels, and seats, and waiting on a new lower console from Al Knoch. Found a pristine gauge cluster off Ebay and modified that a little for the electric oil gauge and Voltmeter. Everything else scrubbed, painted and ready to go.

Ironically they never touched the seats. Brand new leather in the 90s, along with new foam. Perfect. I would post some pics of the carnage, but I am typing this from work right now.
