I've got a B17 with only about 900 miles on it. Not too long ago (300 miles or so) I was caught in a serious downpour. The entire saddle dried out fine, with no problems in performance since, but there is a pretty large water stain on one side of the saddle. This no way affects the performance of the saddle - it's a purely aesthetic concern, but does anyone know of a safe way to remove, or reduce, the discoloration caused by the water?
