Cat urine, carpet and a very rusty floor

Thanks All.

The interior of the car is completely stripped as in no dash, headliner, door panels seats, carpet nothing.

I towed the car back to my house so the problem with the cats pissing in it are over, just the rust and smell.

I power wire brushed the real bad spot yesterday and used baking soda for now, just need to work on the area again and pretty much all the inside because the stench was so corrosive. I did a little grinding on it to get the heavy rust gone, it now has two pin head size pin holes in the floor in the real bad area. SUCKS!
