There was an accident where a non-extinguished candle spilled wax on a drywall. I removed most of it gently with a blunt knife, but there is a big stain left from the candlewax. Since this is an apartment on rent, is there a solution to my problem where I won't have to pay an insane amount of money to my landlord for a repaint?
Generally spilled wax can be wicked up with a brown paper bag or newspaper and a clothing iron or hair dryer. If it is on a painted surface, I would try that or even hot water. If it is on an unpainted surface, then it will need to be wicked up as much as possible and then repaired.
Posting my solution to the problem for future reference:
First, I scraped as much of the wax as possible without damaging the drywall. I was left with a pretty bad oily stain that stood out on the white plaster. I used some dishwasher soap to remove as much of the oiliness but the porous surface has absorbed most of it already. So, I got a repair paint pen (I used the Baufan one, there's many brands available) and it worked perfectly! It required 3-4 applications but it blended seamlessly, and while wet I used a makeup sponge to achieve the texture of the drywall.
