Does anyone know how to properly clean the yellow stitching on my steerng wheel?

My GT2 is an 03, and the stitching is getting less yellow than before from my sweaty hands...

Thanks.

 

Thats funny i just cleaned my stitching on my wheel last night. i just used warm soap and water with a wash cloth.

 

Maybe one of those oxygenating cleaners. Can't harm it I suppose.

 

I use zaino leather cleaner on my whole interior, for the hard to reach areas, or areas with a lot of texture, I use a toothbrush, I have yellow stitching on my daily driver, and it takes the grey to yellow everytime. I imagine any leather/interior cleaner would work.

 

Do you at least use soft bristles? Couldn't resist, it's the dentist in me.
