My interior is black with white contrasting stitching on seats front and rear, door panels, dash, etc.

I want to put leather conditioner on my seats but I'm afraid it will discolor my stitching.

Any advice?

Thanks

Too late to tell you that order was an error. Perhaps you can be very conservative, but ultimately the thread will discolor from embedded dirt.

Porsche stitching these days is nylon thread and will not change color.

IMO, Our leather isn't the fussy expensive type of leather that needs lots of extra care and maintenance. It doesn't need as much conditioning as one may think. If you must, just apply it once and it'll be fine for a long time. Use damp towel followed by a dry towel to clean on a routine basis. Maybe use one of those wipe on wipe off leather cleaning/waxing sheets now and then too. But a massive slathering of cleaner and conditioner probably isn't something that's necessary except maybe three times for the life of the car. just my 2 cents
