Yesterday my son went home from school with ink stains on his shirt, i was very upset because removing ink stain is a very difficult job especially on colored shirts. It’s easier for white shirts since I can use bleaching solutions. Anyway I just search the net for ink stain remover, so far Flexo ink cleaners and Anilox roll cleaner are the products i found online . I’m not sure if these products are effective so I have to search for product reviews first, I always make sure I get my money’s worth.lol
