Getting rid of rain marks on saddle?

i was riding in my crosby saddle (it's a few months old) and it started raining, i got off to go into the indoor arena and it rained a little bit on the saddle. it's been a few weeks and i've cleaned the saddle multiple times and oiled it once, but the marks are still there. the leather scuffs easily when i ride, which sucks, but isn't the end of the world because my leg covers those marks when im sitting in the saddle. however, the rain marks are all over the saddle and i don't think i could show with the saddle in its current condition. does anyone have ideas about how to get rid of the marks? i heard neet's foot (or darkening) oil might get rid of the, but im a little bit hesitant to try that
