"Iron Man" Mozo Skin - Stain removal?

[bijak_riyandi]

Hi guys,
My Iron Man Lumia 950 got stained on the corners and it's bothering me.
I've tried using lab grade alcohol and n-hexane to remove it, but it didn't work and it damaged the leather...

Any ideas of what should I do? I'm thinking of using detergent but I'm still in doubt.
Thanks in advance.

Might be worth asking Mozo and letting us know what they suggest
