Coach leather care product are good for Soho and Hamptons leather series. NOT RECOMMEND for cowhide.
The best way is under the light and rotating for 2 to 3 weeks. Cowhide will become darker from itself and easier to take care.
Leather Preserver will keep cowhide shinny only. Best product is Leather spray but BREE store did not carry in US. You can check from their website and find out if Honkong and Japan will carry.
