How to clean stitching on leather wrapped steering wheel?

[FL335i]

I woud just use a quality leather cleaner and protectant in one. I use meguiars. You can use whatever you want. Wipe the wheel down well and then get a soft toothbrush and hit the stitching gently with liberal amounts of spray. Then do one last final wipe down. 24k on mine, stitching is stark white. I'm on a job site everyday.
