Yesterday I put my bumper case to the table. My girlfriend leave in there a small part of the hair dye, I didn't see, so unfortunately my phone landed on this.
I already eaten my lunch (about 15min) when I realized what happened. First I tried to clean with window cleaner, but I can't clean with this perfectly. After that I tried to clean with various types of cleaner but unfortunately not working.
Than I tried to clean with denatured alcohol, this works perfectly.
Actually my bumper case looks like a new.
