I'm not an expert by any means but I have used Weiman Leather cleaner and Polish and Leather CPR. My Chloe bags are more porous leather than Marcie I think. These products don't seem to change the color of leather and I think both products are silicone free. Others rave about Blackrocks, Appleguard but I tend to buy locally. (Canada) If you have a cobbler, they will carry the better products. I saw you posted in the other thread so I hope this helps.
