IPA will dissolve surface contaminants, but you must wipe it down well or it just smears around.Thanks OG! Guy at the Tesla dealership on delivery day said to use 100% alcohol for spot cleaning. Would that strip the passivation layer?
Regarding the passivation, does that mean those fingerprints are likely from the factory before the self-passivation fully "cured" ?
IDK if factory stainless needs to "cure", but it stays shiny due to the oxidized surface chromium. It actually needs to "corrode" to look shiny. Stainless relies upon exposure to oxygen.
The term "passivization" means treating the steel with acid, which dissolves some of the iron and this increases the proportion of chromium. (We're taking atoms of thickness here, you won't burn though the surface with ordinary cleaning chemicals lol.)
But yeah, if you treat the whole truck with a mild acid like BKF or Citrisurf it will be really really shiny initially, but slowly temper as it oxidizes. That's why it can be problematic to spot-clean with such stuff, since it will make a shiny spot, hahaha, but it will eventually blend in.
