I saw these too when I was last on cleanyourcar.
I was/still am very sceptical to whether these things actually work but having read a opinion from someone on here to say they actually work is good to know.
I'm always cleaning my car and I only allow coffee to be drunk in it no food ect (I would live on coffee if my wife let me...
) so my car (currently MK6) has still got that new smell...or so I'm told.
I might buy one for my wifes neglected Aygo though...so thanks for your thoughts.
