Using anything related to automotive leather cleaning is perfectly fine.
The faux leather in Teslas is polyurethane, which is the same compound used to coat real automotive leather (except in untreated leather cases like the Ford 'King Ranch' seats).
This is a great product for interior cleaning, and yes it's safe on your seats.
But for zinc oxide, sroh is correct in that you usually need the strongest cleaner that is safe on the material, we recommend Opti's
Power Clean. It is a degreaser that is safe on interior components and can be diluted 10:1. To remove zinc oxide it's also helpful to use a
common detail brush to agitate the area, then wipe dry with a microfiber towel.
