You have effectively set and sealed the stains with Apple and altered the special enzyme garment washed italian leather permanently.
Linea Pelle are easy to keep nice with simple methods outlined in this thread.
Thanks for your response Stormy Heart. I took a closer look at my bag today and I think the two stains that I tried to clean a few months ago look okay, I think this one is actually new. I haven't done anything yet and even though I have read this entire thread I am confused on what to clean it with since it's an enzyme dyed leather. I saw something about warm water and a glycerin based soap and then something about leathermagic cleaner. Can you tell me what would be most effective at trying to clean this new stain. After that I plan to treat it with the Wilson's leather spray.
