What's the best way to clean those 2 surfaces, leather and plastic I think.
I tried 3D orange and Chemical guys cleaners, but they didn't work on either. I got Autoglym leather care kit coming in.

Sunscreen stains can actually damage the leather and need to be cleaned immediately. If you google it you find lots of suggestions of how to get it off. White vinegar, baking soda, rubbing alcohol, leather cleaner or degreaser are some suggestions. It looks like you let that sit too long and now it's worked its way into the leather. On the exterior surfaces that should come off with car soap or a detail spray. FWIW, I use Adam's Polishes Leather & Interior Cleaner to immediately wipe off sunscreen stains from any interior surfaces (vinyl, plastic and leather).
