What is granite?
Granite is a hard igneous stone of quartz and feldspar. It resists scratches and acid far better than marble, but it is still porous enough to take stains, especially in lighter colours.
Where does PGS restore granite?
Kitchen countertops and islands, bathroom vanities, floors, stairs and wall cladding.
What damage does granite get?
- Dark patches where oil has soaked in, especially on kitchen tops
- A dull surface from cleaner film or wax build-up
- Chips along edges and corners
- A worn sealer that now lets water in
- Oxidation: yellow or rust-coloured marks from iron minerals in the stone
- Scratches and dull patches on polished floors and tops
How does PGS restore granite?
Deep cleaning and stain drawing, polishing back the shine, repairing chips and applying a fresh penetrating seal.

How should I clean granite at home?
- Use a pH-neutral cleaner and avoid wax-based products that leave a film.
- Wipe up oil at once, before it soaks in.
- Test once a year with a few drops of water. If the stone darkens, re-seal.
