How to care for a Natural Stone Countertop
Natural Stone countertops require a sealer to prevent staining occurring from household liquids. Typical staining agents; coffee, cooking oils, wine, soft drink, sauces etc. Penetrating sealers are recommended and you can choose to use either a Natural Look Sealer or an Enhancing Sealer.
For regular cleaning, a spray and wipe cleaner is ideal. We have 3 types;
- Aqua Mix AquaShield™ Cleaner & Resealer (ideal for honed stone) – a cleaner that tops up the sealer each time you clean, so that resealing is never required.
- Aqua Mix Stone Clean & Shine (best for use on polished stone) – a spray-and-buff routine cleaner that is designed to enhance the natural beauty of the stone as it cleans. Regular use helps protect factory polish.
- Aqua Mix AquaKleen™ – cleans and deodorises kitchens and food preparation areas.
Deep stains will appear darker than the colour of the stone. The most effective method for removing deep stains is by using Aqua Mix Poultice Stain Remover. It is an absorptive clay that is designed to remove deep-set oil and grease stains without scrubbing.
How to Guide:
Etching (dull spots):
Marble, travertine, limestone & onyx are all soft materials which are prone to marking as a consequence of their calcium carbonate structure. Acidic liquids react with calcium carbonate and literally eat away a tiny piece of the polished/honed surface, creating dull spots which are typically called an etch. Contact from acidic materials like lemon juice, wine, coffee, fruit juice etc can create an etch. The more acidic the liquid the faster and deeper the etching occurs.
An etch is not a stain; like a scratch, it effectively changes the surface of the stone. It generally appears as a light, dull mark. Penetrating Sealers cannot stop etching as they are beneath the surface of the stone and not a physical barrier between the acidic liquid and the stone.
Calcium-based stones have three main factors which relate to maintenance, they are porous, they etch, and also scratch easily. Although a penetrating sealer cannot stop etching and scratching, it can reduce the porosity of the stone which will provide stain resistance.
How to Repair an Etch?
Etching is always best to remove using an experienced stone restorer. Contact us if you would like a recommended repairer.
