Cleaning vinyl

Years ago, GoJo cream hand cleaner had just a little bit of lanolin in it. Think hand lotion. It would clean and soften vinyl or leather just as it would any other skin. A cleaner like thinner, mineral spirits, with alcohol in it will strip the oils from the skin and cause cracking. Honestly, I would rather use wifeys hand lotion or even linseed oil.
The linseed oil is what we used on brand new baseball gloves.
Example, My brother has a 93 'stang 'vert' with white leather guts. When his son played baseball there were sometimes 3 players riding. You wouldn't believe how dirty the white leather was. GoJo cleaning made it look nearly new. Use damp towels and some pressure to lift residue. Rinse and wring towels often.
One more example... Dash pad in my 67 notch is just as soft and pretty as new. ( I'm the second owner. ) This dash pad was never cleaned with anything other than cream type GoJo. No armor all/son of a gun/etc.. ever. Those silicone based products will make it shine but also clog its pores. Dash pad aint supposed to be glossy anyway.
