You are right on keeping them clean. Unfortunately over the years the hide and hair will loose the oil it has in it from the tanning process. And I know that more oil attracts dust, BUT if the tanneries use oil in some form, in the first place, it can't be all that bad and has never damaged any of our mounts. Though I don't have anything that I've done thats over 25 years old yet.

FWIW Windex has ammonia, I believe, and that'll even help rid the oil that you need to keep in the first place.
