If you want to make your leather soft, the best thing to use is a leather care product such as neatsfoot oil or leather cleanser (easily available on the online marketplaces).

You can safely Vaseline on most types of leather. However, using too much Vaseline may lead to a build-up and clogging the leather’s natural pores. Vaseline should also never be used on suede leather due to their more delicate finish.

If your leather feels dry, you can rehydrate it using a conditioner for leather, such as mink oil, coconut oil or olive oil.
