It will depend on the ink involved. I can dissolve any kind of ink in the lab (can even tell you who manufactured and what dye lot) but it might destroy your fabric :lol: . Unfortunately, some inks will actually be set by lye based soap (any soap, laundry, body or dish soap has some sort of lye in it) so getting your ink out after using one of these can be a problem. I hope it comes out. I preach the small sample area a lot but sometimes a project looks better if the whole thing gets treated the same way every time. I wish I were more help.
