Dead Animal

The purpose of a pad cleaner is safe removal of dirt Odert Flecker on cushions or textiles.
My wife said dirt from the cushions in the car to remove by this means. The car was new!
When I had to go after a few days with the car I heard a penetrating absolutely disgusting smell.
Common guesswork where the smell came. No one could explain. In the car, I looked for things that were perhaps forgotten, and then slowly rotten. Nothing Found.
Next, I dug out my Wrekzeugkiste. Removed air slots in the engine compartment and controlled. With the flashlight beneath the car for dead carcasses etc. searched. Again, nothing.
Then abgeschnüffelt the entire car interior, and perceived this disgusting smell everywhere. Then I remembered, it may perhaps be of upholstery cleaner. I sniffed at the fractured box in the closet of my wife and had immediately the culprit.
Worse, it can not be. Expiration date, I have found none, maybe it was because ...
But no matter, the box went straight in the bin. Never again this cleaner!
We are now trying for several days the car flash off in good weather outside.
