How can i remove black colour permanent marker pen from a cream coloured leather sofa???
Permanent marker will have permanently dyed your leather and no amount of cleaning will remove the mark. Please do not try hairspray or other solvent based products as this may make it impossible to repair and will probably damage the leather finish You will need to contact a qualified leather technician who will be able to recolour the area for you. Do not use DIY kits off the internet as you need to use a colour that is exactly matched to your leather otherwise the repair will look awful.
