01 The short answer
To get gravy out of granite, work in this order: (1) lift the excess; (2) wipe with cold water; (3) wash with dish soap; (4) poultice the oil out. The key measure: baking-soda poultice, 24–48 h. Rinse with clean water, dry with a soft cloth, and look at the spot from an angle.
Removal is not guaranteed. Use only label-compatible treatments and stop if the material changes.
02 Never do this
- Hot water. Heat helps pigments bond to the fibres, and any milk or other protein in it cooks on.
- 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.
- 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
Lift the excess
Lift any solids or excess with a plastic scraper or an old bank card, never a metal blade on stone. Then wipe the area with a damp paper towel.
Why it works: Removing the bulk first means the cleaner only has to deal with what has soaked in.
2 min hands-on
Wipe with cold water
Wipe the area with a cloth dampened in cold water, then dry it.
Why it works: This dilutes and lifts what is still on the surface before it dries on.
2 min hands-on
Wash with dish soap
Wipe with warm water and a drop of dish soap; on a hard surface, enzymes are not needed.
Why it works: Protein residue on a sealed surface lifts with ordinary detergent once it is wet.

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.

05 Dried, set, or back again?
- Old oil has partly oxidised and gone sticky; apply the degreasing step two or three times, and give powder an overnight stay where it is used.
- 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 gravy is made of
- Oil and fat
- Starch
- Protein
- Dye
The oily part of gravy will not dissolve in water at all. It needs a surfactant such as dish soap, or a solvent, to break it up, and a dry powder can draw fresh oil out before you start.
Starch in gravy swells and glues itself to fibres as it dries. The amylase enzymes in bio detergent are what break it down.
Gravy can include protein. Heat can make protein-containing stains harder to remove. On washable materials, cool water is a common first step. A protein-digesting detergent is an option only when its label permits the actual fabric; use a suitable delicate-fabric detergent on wool or silk.
Gravy 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.
- Gravy is fat, flour or cornstarch, meat protein and browned colour. It needs an enzyme for the starch and protein and a degreaser for the fat, in that order.
- Starch that is ironed before it is washed out goes stiff and shiny.
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.
08 Next time
Pass gravy in a jug with a saucer underneath, and treat drips with cold water before the starch dries stiff.
09 Questions
Can I use hot water on gravy on granite?
No. Heat helps pigments bond to the fibres, and any milk or other protein in it cooks on. Keep to cold water until the stain is completely gone, then wash as warm as the care label allows (up to 60 °C (140 °F)).
Does vinegar help with gravy 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 gravy?
Not chlorine bleach on granite: repeated bleach can degrade the sealer on granite.
Will gravy come out of granite completely?
Removal is not guaranteed. Use only label-compatible treatments and stop if the material changes.
When should I call a professional?
Rust stains, large oil stains in light granite, and resealing.
