If you've been treating your leather jacket properly, you should get it professionally cleaned at least once a year, if not more, depending on how often you use it. I was once cleaned my husband 's brown leather jacket at home. It ruined and start cracking after 2 days. A qualified leather cleaning service can restore the vibrancy and repair the damage to your leather jacket if it has gotten dusty, has lost part of its color, or has developed cracks, allowing you to continue wearing it for years to come. Leather jacket care is necessary to increase the life cycle of your leather jackets.
