The best care is non-neglect! Keep using it - the oils from your hands or body will constantly nourish the leather, keeping it from moulding or drying out.
Keep away from extremely wet or hot places. If you do get your product soaked, remove all items from it and dry it in a well ventilated area, away from direct sun to prevent sun-tanning or drying out the natural oils within the leather. In front of a fan, by a window, overnight is fine.
This product is also really good for nourishing your veg-tan leather goods. Every 2-3 months is great, 6 months if you're busy, yearly at minimum if you want it to last.
