I haven't tried this out on cars, but, that traditional fat "Nivea cream" that still comes in a blue tin can, has worked for me on several leather applications, and even to soften some rubber.
(On this same note, I've also used, on occasion, those tissues normally used to wipe baby's asses!)
Is this a bad idea to use anywhere on a car?
Of course, I'm not thinking of "creaming" away, and getting muddy parts as soon as summer starts sending dust and sand along with the wind.
I'm referring for instance using it on leather gearbox sleeve, and driving wheel, for example.
Complete newbie! Feel free to insult me at this point
