I have a 2018 M3 with only 13k miles on it and its constantly garage kept. I just recently noticed this strange white stuff in the groves of the leather patterns of the entire top of dash. Its rarely out in the sun but even if it were every day there is no way the dash leather is ruined or has an issue. I tried to clean it with damp/wet cloth and it just turned white again. What gives?
BTW: Its never been treated with anything. SHOULD I treat it? And if so, what is recommended for dash? Is this stuff recommend?:
