If the black seats are faded, then I would suggest masking off the red stitching and carefully use the Black Leather Reviver to restore the faded colour, however, if the seats aren’t faded, it isn’t really worth the risk of using the Black Leather Reviver, and you may as well clean and protect the seat with the neutral Leather Ultra Proofer!
Both the Black Leather Reviver and the Leather Ultra Proofer will clean your seats, and also protect them with a three in one protection:
2.) A UV Inhibitor.
3.) An advanced anti-bacterial guard, effective against super-bugs!
You may also notice that each product is leather scented – which is a nice little bonus!
Anyway, it sounds to me like it would be wiser to go with the Leather Ultra Proofer, to completely remove the risk of accidentally colouring the red stitches!
Don’t forget to use the product sparingly, gently massaging into the leather in small circular motions with a clean, lint free cloth.
