More interior cleaning

Last week or so I brought my daughter to her work. Something I never do but I wanted to make a testdrive :-)
So reluctantly she stepped in but regretted it as the car was smelling a bit. She was right though, it's having a bad odor despite I had already cleaned the carpet and used cockpit spray. The velour seats do look OK though but likely are the cause of the bad smell. So I had ordered this foam cleaner by Turtle Wax which comes with a nice intergrated brush. So I soaked it with foam and used the brush. What can I say, it smells so much nicer now :-)  Curious what she will say next time.
