How can you remove Permanent marker ink from leather car interior?
Permanent markers (depending on the dyes used) will have permanently dyed the leather. Anything that claims to guarantee to remove it will also damage the finish on the leather. Use a foam water based leather cleaner to see if it makes any difference if it doesn’t then much stronger chemicals have to be used which will as I have said damage the finish so are best left to a qualified technician who will aslo be able to recolour and finish any areas that need it. Please do not use baby wipes on leather furniture they will damage the finish. Magic erasers act like very fine sand paper so will almost certainly remove finish and/or pigment along with any felt tip it removes. Solvents and alcohol will damage the leather finish and hairspray can be very problematic to fix if it doesn’t work as it will spread it further and may be impossible to remove. Leather needs gentle cleaning and the products should do the work , any scrubbing will damage it. I don’t know where the idea of milk came from
To remove an ink stain from leather you need a specialist ink removal product. Something that will emulsify the stain and then something to absorb it once it has been emulsified, i.e. something to stop the stain spreading.
