To protect a lambskin leather jacket, apply a lambskin protectant before wearing it, clean stains with a dry, soft cloth and periodically condition the leather to prevent dryness and cracking. When storing the jacket, be sure to store it in a cool, dry place.
Lambskin leather is fragile and requires special care. When applying a protectant spray to the jacket, make sure the spray is for delicate leather; spray it on evenly and do not rub it in. Do not use water when cleaning stains from the jacket, because it darkens the leather. For tough stains that a dry cloth cannot rub out, take the jacket to a professional to avoid ruining it. Before conditioning the leather, try the product on a small spot first to make sure it is effective. Use a soft hanger to store your jacket, and do not wrap it in plastic or place it within direct sunlight.
