Hi there guys, new here so hopefully somebody may be able to give me a little help! I've got a fiat 500 with red/cream interior, the bottom of the seats are red cloth and have got some sort of stains on them, they've been shampooed and I've used ambersil upholstery cleaner on them, no joy! Please help? With them being red the stains stand right out! I've attached an image of the kind of seats they are, not mine but they are the same! Thank you
