First up, the heavy hitter. Grab some rubbing alcohol (isopropyl, 70% or higher) from the medicine cabinet. You want a cotton ball or a soft cloth, not a paper towel (those can leave fuzz).
Dab the cotton ball in the alcohol. Don’t soak it—you’re not baptizing the wall. Just damp. Then, blot the pen mark gently.
Watch it dissolve. It’s magic. Seriously, the ink just melts away like a bad memory. Use light pressure, or you’ll smear a mini masterpiece across your beige wall.
Once it’s gone, wipe the area with a damp cloth. It’s that simple. Most ballpoint pens surrender immediately to this trick.
When It's Fresh Ink (The “Oops, I Literally Just Did This” Method)
If you caught the crime in the act, you have a secret weapon: white vinegar. It’s already in your pantry. Dip a cloth in it, rub gently, and the fresh ink lifts off like a lazy cat.
Still stuck? Try hairspray. Spray it directly on the mark. It smells like a salon from 1987, but it works. The alcohol in the spray breaks down the ink fast.
Just test any of these on a hidden spot first. I learned that the hard way. My wall now has a permanent "test patch" behind the couch.
