Cleaning and Detailing

Does anyone have any ideas on the best to clean a grease stain from a velour covered driver's arm rest. I have some of this stain and want to remove it but SAFELY ??

Much appreciated

Have you tried Velvet soap (or pure soap) and water with a small brush (like a nail brush)?
I was amazed to see this method remove a large ball point pen ink stain.
Sometimes the simplest things work best.

I would try a damp Mr Clean Magic Eraser. Try it in an inconspicuous spot first.
