Just wanted to post the link to the Product Care and Cleaning info on dooney.com. I know many have been wondering how to care for your Dooneys and the answer is simple: you don't need to.

Dooney specifies that their products do not require creams, polishes or leather conditioning products to maintain its beauty.
This includes the florentine leather.
For the light, 'naked' vachetta trim leather:
'Vacchetta Leather
The pale tan Vacchetta Leather used in Dooney & Bourke merchandise is untreated. This "naked" leather will naturally darken over time with use and exposure to light. Vacchetta Leather requires no creams, polishes or cleansers to maintain its beauty.'
From personal experience, I have never used any treatment products on my Dooneys.
The info on their site is great and you can view the care information by collection so you know exactly how to care for each type of leather. They even have care info posted for discontinued collections.
