Staining?
No need to panic. Saphir's Reno Mat is your ally! Just dab the spot gently with a cotton pad. Leave for a maximum of 10 minutes.
As Reno Mat dries out the leather, wax and nourish your leather once the stain has been removed.
If you've made a greasy stain... you'll need to sprinkle some terre de Saumières (montmorillonite, or bentonite clay : you can find it on internet. If you can't find it, try with baby powder! )
Let it absorb the grease overnight. Then wax!
Once your bag is weathered and has acquired its beautiful patina (yes... again this patina), it will be much less vulnerable to stains!
