01 The short answer
To get permanent marker out of granite, work in this order: (1) wipe with alcohol; (2) poultice the oil out. The key measure: baking-soda poultice, 24–48 h. Test rubbing alcohol on a hidden spot first. Rinse with clean water, dry with a soft cloth, and look at the spot from an angle.
This has a higher editorial difficulty rating. Consider professional cleaning rather than stronger or repeated home treatments.
02 Never do this
- Water first. Water spreads alcohol-based ink and does not dissolve it.
- Vinegar or lemon as everyday cleaners. Repeated acid wears down the sealer that keeps the next spill out.
03 Before you start
- Use white cloths or paper towels only: coloured ones can transfer their own dye into granite.
- Identify the stone and finish. Water absorption does not by itself establish sealer failure or a need to reseal; ask the stone or sealer supplier.
- Rubbing alcohol: flammable: no open flames, and let it evaporate before using heat.
- Rubbing alcohol: never mix with chlorine bleach (chloroform and other toxic compounds).
- Pretest every permitted treatment on an inconspicuous area, including trims, and let it dry. Stop for colour transfer, lightening, rings, stiffness or distortion. A successful spot test does not guarantee the whole item is safe.
- The listed products are not permission to combine treatments. Use each only if the exact item and product labels permit it, including any change of product. Rinsing or blotting does not establish compatibility; ask the manufacturers or a professional if unsure.
04 The method
Wipe with alcohol
First try scribbling over the mark with a dry-erase marker and wiping it off straight away. If a trace remains, wipe with rubbing alcohol on a cotton pad or cloth until the ink lifts, then wipe with a damp cloth and dry.
Why it works: Alcohol dissolves the ink without abrasion.

Poultice the oil out
Wash the surface with a few drops of dish soap in warm water first. If a dark patch remains, it has soaked in: mix baking soda with water (or acetone, for stubborn oil in dark granite) into a paste like peanut butter, spread it 6 mm (¼ in) thick over the stain, cover with plastic wrap, tape the edges, poke a few holes, and leave it 24–48 hours. Scrape off with plastic, rinse and dry.
Why it works: A poultice draws oil out of porous stone as it dries, the only way to reach a stain that is inside the stone.

Rinse, dry, check
Rinse with clean water, dry with a soft cloth, and look at the spot from an angle. Ask the stone supplier whether sealing is needed; a quick water-darkening test does not establish sealer failure.
Why it works: Sealed stone resists the next spill; a dull patch tells you the polish needs attention.
2 min hands-on
Test first: rubbing alcohol on granite. Ask the supplier whether this stone needs sealing and how to assess its protection. A water-drop timing test alone is not a reliable resealing diagnosis.
05 Dried, set, or back again?
- A dried dye or tannin stain may persist. Stop if any colour transfers, the texture changes or a ring appears; do not repeatedly bleach or scrub a stubborn mark.
- A stain that has been in stone for weeks needs a poultice, sometimes two or three applications 24–48 hours each.
Assess the mark only once the item has dried according to its care instructions. If it remains, do not keep repeating or strengthening treatment; obtain advice for the exact material and product.
06 What permanent marker is made of
- Dye
- Polymer
Permanent marker carries dye that soaks into fibres rather than sitting on them. Depending on the dye, alcohol dissolves it, oxygen bleach breaks it down, or sunlight fades it, and speed matters more than strength.
Permanent marker is a polymer: long molecules that set into a film or a sticky mass. Each one needs either its own solvent or a change of state, freezing or softening, rather than scrubbing.
- Permanent marker ink is dye dissolved in alcohol with a resin binder. Rubbing alcohol, or alcohol hand sanitizer, redissolves it.
- On non-porous surfaces, drawing over it with a dry-erase marker and wiping often lifts it: the dry-erase ink's solvent redissolves the permanent ink.
07 The material: granite
It tolerates hot water (up to about 60 °C (140 °F)) for the final wash, but only after any protein has been rinsed out cold.
- Granite is mostly quartz and feldspar, so it shrugs off acids far better than marble, but its sealer does not.
- Oil stains in light granite show as dark, blotchy patches; an acetone or baking-soda poultice draws them out.
The granite file rates every common cleaner for it.

Keep permanent markers out of reach of small children, and put paper under anything you are labelling.
09 Questions
Can I use hot water on permanent marker on granite?
Warm water helps here once the first steps are done; stay within the care label (up to 60 °C (140 °F)) and check the stain has gone before any dryer.
Does vinegar help with permanent marker on granite?
Keep vinegar away from granite. Repeated acid wears down granite sealer, and some granites contain calcite that etches.
Can I use bleach on permanent marker?
Not chlorine bleach on granite: repeated bleach can degrade the sealer on granite.
Will permanent marker come out of granite completely?
This has a higher editorial difficulty rating. Consider professional cleaning rather than stronger or repeated home treatments.
When should I call a professional?
Rust stains, large oil stains in light granite, and resealing.
