The only horse related leather preparation that I might consider using on the car trim is Stubben Hammonol which is great for putting the flex back into dried out leather - but I have not tried it yet. You may find the smell a little off putting. Otherwise I stick to Autoglym hide food etc - although recently I have tried a Halfrauds own label product and been pleased with the results and the lack of clothe damaging residue. Management would have strong views on any residue ......
