Plug the drain of your bath tub and turn on the hot water tap. Fill about one-third of the tub with hot water and close the bathroom door to fill the room with steam. It you have no bath tub in your bathroom, fill a large bucket with hot water.
Place a citrus freshener in the hot water to release the scent throughout the room.
Place the leather item in the bathroom with the citrus scent or about 30 minutes.
Mix 3 1/3 cups of olive oil, 1/3 cup castile soap, eight to 12 drops of grapefruit seed extract and 1/2 gallon of water in a gallon jug. Add 40 to 60 drops of an essential oil with a scent that you like.
Pour the mixture into a spray bottle. Spray it onto the leather material, then rub the leather with a clean cloth. The scent of the essential oil will remain in the leather.
