I am, at the moment, cleaning a number of leather items out of a saddlery display. What I have been using is raw, unbleached sheep’s wool. I clean the article with a damp cloth to remove any surface dirt, then rub down the leather with the sheep’s wool. Many of these items have been left out in the elements for 20-30 years, and this method seems to be working. I usually let the artifact sit and ‘dry’ before adding a coat of Cellugel, to help repel redrot. I too would look forward to the webinar on leather care. If interested I can forward some before/after photos.
