Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Granite is very hard, so most lines that look like scratches are metal marks left by cookware, and a non-scratch cream cleaner removes them. Genuine scratches in granite are rare and are polished out by a stone restorer with diamond pads. Fine marks can also be in the factory resin coating rather than the stone.
First, check what you are dealing with
- Grey line that feels smooth: metal mark. Clean it off.
- Line in a resin-filled area: scratch in the fill.
- Line you can feel in the stone: rare true scratch.
What you need
- Non-scratch cream cleaner
- Soft damp cloth
Step by step
Rule out metal marks
Rub the line with a non-scratch cream cleaner and a damp cloth. Grey lines from pots and cutlery often disappear completely.
Check again
Dry the area and look at it in raking light. Whatever remains is in the surface.

A stone restorer can re-polish granite with diamond pads and draw out deep stains.

Understanding scratches on granite
Granite is around 6 to 7 on the Mohs scale, harder than a knife blade, so most marks that look like scratches are actually metal left on the surface.
On polished granite, problems usually show as dull traffic areas, dark oil patches on lighter slabs, or water spots on dark ones.

Good to know
Most "scratches" on granite are metal left behind by pots and utensils. Try a non-scratch cream cleaner before assuming the stone is damaged.
