What Does the Granite Stain Look Like?

Granite stains can appear differently depending on the source, granite colour, finish and depth of absorption.

Dark Absorbed Patch

A dark irregular mark that may involve oil, grease, moisture or another substance absorbed into the stone.

Sink and Wet-Area Staining

Marks around sinks, taps and wet areas caused by repeated water exposure, minerals, residue or contamination.

Avoid repeatedly applying bleach, strong acid, abrasive powder or random stain removers. An unsuitable product may affect the finish, spread residue or make the mark harder to assess.

See the Difference After the Right Test

DUSH may recommend a controlled test area or customer sample so the granite's response can be evaluated before treating the complete surface.

Results depend on the granite type, stain source, depth, age, finish and previous cleaning attempts.

How DUSH Handles Granite Stains

01

Send Photos

Send one close-up photograph and one wider image showing the stain and surrounding granite surface.

02

Assess the Mark

The technical team reviews the granite colour, finish, stain pattern, location, likely source and previous cleaning attempts.

03

Test and Recommend

DUSH may recommend a sample treatment, controlled test patch, site assessment or suitable cleaning, restoration and protection process.

The process is selected according to the granite and stain condition — not simply one chemical.

What May Be Causing the Granite Mark?

Oil and Grease

Cooking oils and food residue may create dark absorbed patches.

Water and Minerals

Repeated moisture may leave dark zones, deposits or marks around wet areas.

Rust or Metal Contact

Metal fixtures, utensils or contamination may create brown or orange marks.

Cleaning Residue

Unsuitable products, soap or coatings may leave cloudy or uneven areas.

Different causes may look similar. The stone, location and stain history should be reviewed before treatment.

The Goal Is a Clean, Natural Granite Finish

The treatment should improve the visible problem while preserving the granite's natural mineral pattern, colour and surface finish.

Common Questions About Granite Stains

Some stains can be reduced or treated, but the result depends on the granite, stain source, depth, age and previous cleaning attempts.

A dark area may involve absorbed oil, moisture, residue or an existing coating. Photographs and testing help identify the likely cause.

Some absorbed oil stains may respond to treatment, but older or deeper marks may require controlled testing and more than one step.

Repeated water, minerals, soap, food residue or moisture may affect the granite around frequently used wet areas.

Avoid aggressive cleaners without technical guidance. They may affect the finish, surrounding materials or existing treatment.

The visible appearance may change as residue or staining is reduced. A small test area should be reviewed before wider treatment.

Protection may be recommended depending on the granite, porosity, application area and exposure. It should be selected after assessment.

Send one close-up, one wider image and a photograph showing the complete countertop, floor or wet area. Include your city and how long the mark has been present.
