Blue marks on the inside of my car door(on the leather part) from rain?

I went to the gym, it was hot and sunny so i l left my windows cracked, then started pouring. When i went inside i see blueish marks from the rain. Is it permanent? Do i need to get new leather frabic for my car or can i clean off the stains with a special cleaner?
I have a 2017 ford mustang ecoboost

First, try wiping the leather with a damp cloth. If that doesn't work, try a good quality leather cleaner. If that doesn't work, take the car to a good auto detailing shop and ask if they can help you.
