The ink won't wash out. If it is a lot of ink, it could bleed and spread if you wash it. Usually it isn't a good idea to work too hard on ink because anything that might affect it will lighten the leather around it.There are some red ink stains, what appears to be a giant greasy spot on the bottom, and some remnants of sticky stuff on the bottom. How would I wash it?
You can use cornstarch + heat for the grease stain - you cover it with cornstarch, put a paper towel over it, then hold a hot iron over it - I've never done it so I don't exactly how to do it. However, the heat could help set the ink, making it even more impossible to remove.
The sticky stuff might wash out in the bath or you might have to use something like goo gone or goof off, which might also leave a stain so you should probably test it some place.
It would be much easier to help you if you could post pictures.
