I’ve had amazing success with bleach in a spray bottle. I used to try to paint but it’s always noticeable and never completely matches. Make a mixture of 1 part water, 1 part bleach in a clean spray bottle. Cover anything nearby so you don’t spray bleach on it (including painted walls). Soak the area, but not so much that it drips. Walk away. After it dries the area should be noticeably whiter. 1-2 applications is all I usually need to get it completely removed.
