Go to the pet store and buy a product called "urine-be-gone". It's made to get rid of cat piss. It is amazing. My neighbor bought a used freezer that smelled like it use to house a dead body. He was gonna toss the freezer. He had bleached it, scrubbed it, cleaned it every way possible and it still reak'd. I told him about this product and he called a few days later to thank me. He spayed the "urine-be-gone" on it and it was all better.
Apparently the spray has an enzyme that kills bad smells. Give it a try.
