Hello everyone, 
I would like to apologise if this is not the proper place for this question. 
So I have a new pair of leather sneakers, all white. 
But found a new stain on them which kills me. 
What is very strange: looks like the unknown solution, went throw the paint itself and detach the paint from the leather surface. So there is a spot where the paint is no longer adhered to the leather. How is this even possible?   
Would like to know your feed-back. What can I do to fix this? Can I do anything? If possible would also like to attach a photo or a video of the "problem". 
Thank you and excuse my ignorance.
