Can anyone tell me how to clean a ketchup stain off of the leather on my coach bag.
I haven't had that happen to me, so I don't know. I'd suggest asking in your local Coach boutique, or contacting Coach customer service and asking them how you should do it.
I wish I could be of more assistance.
What kind of leather is it (meaning pebbled, vintage, etc.) because they are all a little different and they all have different methods of cleaning. If you aren't sure what kind of leather it is you can post a photo here and we can probably identify it for you. Also, what color is the leather?
In the meantime, here's a link to Coach's website about cleaning:
