Can you soften a leather jacket with WD-40?

Yes, you can use WD-40 to soften a leather jacket, but it is not the most recommended method. WD-40 can help condition the leather and make it more supple, but it may also leave an oily residue and affect the jacket's finish. It's better to use products specifically designed for leather conditioning to ensure the best results and maintain the jacket's integrity. Always test any product on a small, inconspicuous area first.
