White stitching

[Silverwing]

I'm trying to clean all the white stitching on my black leather. Car is still relatively new but the stitching on my center console and steering wheel has gotten noticeably darker than the rest of the stitching. Does anyone have any recommendation on cleaning the stitching to get it a brighter white without damaging the leather? 
Thanks.

A little leather cleaner and a boats hair brush should get you where you want to be. Be gentle. And no stiff bristles.

A tooth brush might be good. I use that to clean the stitching on my steering wheel, strong enough to get gunk out and soft enough not to rip out the stitching. It also is small enough that you can focus on a small area

Tooth brush for sure.  Whatever you use to clean it, be sure to follow up with leather conditioner around it.

Thanks guys, figures that leather cleaner is the one chemical I don't have. Gonna order it now.
