Anyone been using hand sanitizer in the car? Thats what it looks like to me. I had something similar on a leather center armrest from someone dropping a blob of hand sanitizer on it. I thought it was ruined. But, I took a little bit more hand sanitizer on a microfiber towel and wiped it down and kept wiping until it evaporated off and remarkably it all came out.
I wouldnt use brake cleaner. I think that may may the situation worse, not to mention the smell will linger.....
