After much reading of various teks that use naphtha I have begun to wonder if it has any potential impurities it might leave behind after evaporation. I have searched and found multiple opinions but nothing I can view as a general concensus, any information would be greatly welcomed and if this is the wrong area or if I have simply missed something I am sorry as I am new here and still trying to navigate the website as I'm not very computer savvy.

Thank you for any help

^^ what he said. Yeah it takes a lot of time to study.
Light naphtha like hexane and heptane evap fast and more thorough, heavier naphthas like white spirit evap hard and you likely get smell a loooong time. Naphtha is not just naphtha.
Panel wipe's are the fast types.
