Hi Steve,

Liking the quote 'A Morgan is for life, not just for Sundays'

Leather needs to breath and there are lots of options for cleaning it. I would use a cleaner and then something to nourish the leather again. You can also use a cleaner and then a magic sponge to clean marks off of the leather.

Its very hard to clean damaged leather........
