For a light conditioning, as in the bag is in decent shape, I have used Lexol conditioner first as a go to and have graduated to Cadillac Supreme. My guess would be the
Coach moisturizer would be good. I have heard people says good things about it on other threads. For curiosity sake, I plan on picking up a bottle next time I go to an outlet. I would be hesitant to use a weatherproof creme or mink oil product as there is a possibility they have silicone or sealant products, which would be overkill for my bags. And sealants affect future conditioning. Great for boots and shoes though, who are subject to more abuse.
I am doing a light condition every few uses, it seems these days.
I use Lexol leather cleaner to dunk, as I heard of it early on in another blog, but have used Dawn (hey if it cleans up oily ducks!), my go to in the kitchen and my Castile soap facial cleanser. All work for me. YMMV! For light cleaning, I like to put water and a little Lexol cleaner in a bucket. Wipe down the bag with a damp cloth, then wipe down with the Lexol solution. Saddle soap always struck me as too heavy, waxy for my bags. Great for shoes and saddles though.
As cheap/frugal as I can be, esp with bag purchases, I am willing to spend $ to experiment and try different leather products. Since this is a hobby for me, as well as means of purchasing bags that I use and enjoy, if I spend a little on something that is a hit or miss, it pays off in knowledge for what does and doesn’t work.
