I had recently purchased a used Billy Cook saddle. I had taken it in to have it "professionally" oiled. My saddle was a chestnut color when I took it in and when I got my saddle back it was black! The place that oiled my saddle said that it would take several months for the oil to dry before it would go back to the origional color. Right now the saddle if blotchy in color all over. It has three colors right now....chestnut, reddish brown, and black. I believe the over oiled my saddle. Is there any way I can remove most of the excess oil on the skirting and fenders? Someone told me to wash my saddle with Dawn Dish soap and scrub it. Then after dry condition the saddle. Would Dawn dish soap be ok for the leather or would it harm my leather?
