How to Remove Permanent Marker from Walls

The Logic Verdict

My Take: Mike points out that these Sharpie scribbles have sat on his hallway wall for years, so he wets a Magic Eraser at the sink, squeezes it out, and glides over the lines with almost no pressure. He’s honest that melamine can dull latex paint, so he always spot-tests first, but the ink still vanishes in seconds without repainting.

The Science

Permanent marker uses resin-based dyes that lock into the top microns of latex paint. A damp melamine sponge works like an ultrafine sanding block: the foam’s hard polymer cells shave off the stained paint while water lubricates the pass so you don’t gouge the wall. Rehydrating the ink a bit with water also keeps it from smearing as the foam lifts it away.

Step-by-Step Removal

1. Test the finish. Wet the melamine sponge and rub a hidden section of trim. Stop if you see unacceptable dulling.
2. Soak and wring. Hold the sponge under cool water until it’s saturated, then squeeze so it’s damp but not dripping.
3. Erase with light pressure. Glide the sponge over the marker in short strokes. Let the foam do the work—Mike barely presses even on six-year-old doodles.
4. Wipe and inspect. Buff the area with a clean microfiber cloth and let it dry. Repeat the eraser pass only if a faint shadow remains.

Parts & Tools

• Mr. Clean Magic Eraser Extra Durable (Amazon) – The melamine pad Mike wets before scrubbing.
• Chemical Guys Professional Grade Microfiber Towels (Amazon) – Soft cloth for drying and checking the paint finish.

What NOT To Do

• Don’t skip the test spot—gloss and eggshell finishes can burnish quickly.
• Don’t use the Magic Eraser dry; without water it bites into the paint and leaves chalky halos.
• Don’t bear down hard trying to go faster; excessive pressure removes sound paint along with the ink.
