Marker removal
Not sure if this is the right place or not but hoping to get some help with this one!
I’ve recently acquired this vest to use for some hobby stuff (reenactment) and got a good deal on it due to the amount of modern graffiti on it.
The graffiti is definitely period original and so I’m looking at removing it.
Does anyone have any ideas or suggestions to try and get it out? As best as I can tell the graffiti seems to be done with some kind of marker, and the shell of the vest should be a tight weave cotton poplin (I believe).
I had read that acetone or isopropyl alcohol could be used to reactivate and remove the ink and while it is working it’s also bleaching the green from the vest (see the heavily faded patch on the back).
So, does anyone have any recommendations that might work without stripping the green?
