Dust and clean off your leather furniture with a soft cloth. This removes dust, pet hair and dirt that might stain or scratch your furniture when you try to polish it. Discard the used cloth.
Pour a nickel-sized amount of leather conditioner onto a clean cloth and smear it over the cloth with your fingers. Start at one side of your leather piece, near the bottom and rub the cloth in even, firm, circular strokes over the leather.
Continue rubbing until your cloth no longer leaves a shiny trail behind it. Apply some more leather conditioner to the cloth and pick up where you left off, making sure to overlap the last layer of conditioner you applied. This ensures that the entire piece is treated.
Apply leather conditioner in the evening and do not sit on it again until the next day. This allows the conditioner to sink into the leather and dry properly and prevents stains on your clothing.
