I recently bought a car that has leather seats and the front passenger seat is as hard as a rock. I've been using a conditioner to soften it but I've not been making much progress with the stuff that i'm using (leather honey).
I've been doing some reading and I understand that Neatsfoot Oil is used to soften leather saddles and baseball gloves.
Fiebing's 100% Pure Neatsfoot Oil, 32 oz. - 5019779 | Tractor Supply Company
Has anyone tried using it on automotive leather?
I'm not bothered about the color getting darker as the seats are black.
Opinions are gratefully appreciated.
