How to sanitize interior after long-term rodent intrusion?

I picked up an old barracuda, but had to store it at a friend's house for several months until I could make room for it. In that time some mice got in there and did some damage. They chewed a hole in the headliner on one side, and a matching hole on the other side, too. Probably the worst was the smell, especially pungent on a hot day. A friend recommended and gave me a little jar of this stuff called "Pet Mute"(I think). It was a powder which you mixed like 100:1 w/ water. I just spritzed it on the carpet, let it dry, and vacuumed it and it took out probably 90% of the smell. I reapplied it one more time and it was great. That was like 30yrs ago, so I don't know if it is still sold anymore .
