My 3 month old red patent leather studded purse got a 1.5 X 3 inch ink transfer on the smooth side panel. Soap and water did not remove it at all. So I wrote the Valentino customer service department for advice on how to get the stain off and they said to contact the store where I bought it. NOT IMPRESSED! For $3750. you don't get customer service?? Anyway, I read the suggestions and decided to try the Lysol disinfectant spray on a Q-tip. I saturated the Q-tip and lightly applied it to the stain. It came completely off except for a slight smear--so I reapplied on a clean Q-tip and it not only totally came off--but it didn't dull the finish or leave any residue. Very impressed!
