I recently ran over a dead deer and had fur, meat and guts all over my underside.

The worst smell came from the flesh that was cooking on the exhaust.

I put the car on rhino ramps, sprayed the underside down with orange degreaser spray and risnsed it off with my husky power washer. Not only did I wash off all the deer guts but decided to clean the entire underside and now it looks brand new!
