Rode my Brooks, shower-capped, in the rain for many ours this weekend. Didn't get soaked, just a little sprinkled at quick stops when cap wasn't on earlier in the day, but spent most of the time under a shower cap. Took off shower cap for the car bike rack ride home.
Next day, I noticed some dirty patches on the leather. Not sure if it is mold or just dirt.
Stuck on good. Cannot rub off with a regular dry towel, and didn't want to wet the saddle.
Anyway, how to clean it off without wetting the saddle?
Any tricks?
Or just proofhide it and forget it?
