Leather bags are easily absorb grease and oil. Be careful where you place your bag and make sure your hands are clean.
Do a quick cleaning every few uses with a soft, dry, or slightly damp cloth. (Do not use too much water; leather takes time to dry.)
Once or twice a year, do a more thorough cleaning to remove dirt buildup. Wipe down your leather bag with a leather cleaner. Apply in a circular motion, and wipe off with a slightly damp cloth to avoid clogging the pores of the leather.
Leather needs conditioner once or twice a year to stop it from drying out.
To prevent flaking and wrinkling, apply conditioner to a soft cloth and gently rub over entire bag.
Depending on the dryness or humidity in your climate, apply conditioner at least twice a year, up to once a month or so, to keep your leather bag soft and supple.
Air your leather bag once every two weeks to prevent mold growth. Do not store in an airtight container.
If your handbag t gets very wet, wipe off excess moisture as soon as possible. Do not dry the leather with a hairdryer; let it air dry, and then apply a leather conditioner.
Do not use cleaning products that contain alcohol, as these will dry out and possibly discolor your leather purse or bag.
