This will do the deed, no maybe's or just-about's.
Hydrated Lime. Just dump the lime on the offense and let it set. The lime will pull the funk and hold it, after a week or more clean up. If there is still a problem drop the lime again.
Now, my possum story. When I was a kid we moved into a huge old house. (6500 sq ft) My Dad was a handy man type so he did all the painting and such. We were painting the "parlor" around the fireplace and my Mom said "Doug, there's something dead under the house." He says, "Woman, you're just smelling things again, leave me alone." Second night same story.... leave me alone.
Third night Daddy tells me, "My damn paint smells like Hell.... It must be going bad." We then decided to investigate under the house. We found a dead, turned-to-soup possum with three little poss-i thrashing around in the liquid she-possum.
After considerable gagging we managed to spoon the affair into a double bag to put out for the city to pick up on the next debris pick up day. The next day, after sitting in the sun, that bag had swollen until it was no longer black, but almost see-thru.
Daddy comes in from work and says we can't wait for the city, we have to take it up-town and put in a dumpster that will be emptied in the morning. So he backs the 71 VW Super Beetle next to the bag, tells me to grab the bag and "Whatever you do, don't drop that bag and let that **** spatter on my car!"
We ALMOST made it to the dumpster. I told him I couldn't hold on any longer and he pulled into a huge pile of brush a neighbor had on the street for city pick-up He says, " Set that bag down eeeeeaassssy." I do and we circle the block and head home. Then he says, "Don't tell you mama what we did."
O.K., everything is good, responsibility shifted, we are moving on. Mama is on her way to work and sees the people doing pick-up. She hears a loud scream and sees the guys running away from the brush pile like they were running from a bag full of possum soup.
After school that day she asks me what did "You and your Daddy do with that bag of possum???"
When pinned down you can't lie to Mamma..........
