Go to the supermarket and buy a box of bounce, stuff a couple of sheets under your front seats, they will last for about 3 weeks, after that just change them

On your recommendation Mr Skippy41, I tried this bounce stuff in the way you described.
It worked well,
BUT .....
I found the faster I drove, the harder it was to control the vehicle ..... I just could not stay in one place in my seat.
Despite the lovely smell, I quickly concluded it was too dangerous to continue using bounce & so threw it out from under my seat.
