I have a paper on the wall where I used to write with felt pens. Another day, I accidentally left a wet rag hanging over it. I did not realize until now that the rag soaked both the paper and the wall as at present, I have dry pen ink on the wall.
Since I am renting this apartment, I require some cheap solution or hacks to clean it up and I did not want to risk anything so that it could not go even worse.
I tried with a wet sponge but realised that paint on the wall is very thin and the stain is not going away....Please help providing me any hacks for this.
