I have shiny cream leather sofas. My grand-daughter wrote several lines and made many drawings on them using a black coloured ballpoint ink pen. On the other sofa's she wrote with blue coloured ballpoint ink. What must I use to clean and remove these two types of ink on my leather sofas without damaging the colouring or paint on the sofas?
I have found that hair spray or fingernail polish remover has worked for me in taking out ink marks. I would try both or one on a spot of leather where no one can see if it does not work. You will have to make a small ink mark first to see if either works, but out of sight.
