Bianco Carrara marble is beautiful, but it requires careful maintenance in the kitchen. Read about acid damage, impregnation, daily cleaning and prevention.

Why Bianco Carrara is so loved — and so vulnerable

Bianco Carrara is the classic marble. Its soft white colour, subtle grey veining and timeless appearance make it easy to understand why so many kitchens are built around this material. But marble in the kitchen is also one of the most maintenance-sensitive choices you can make.

If you understand that before installation, you can enjoy it for decades. If you are not prepared for it, you may be confronted with stains, dull patches and acid damage that can become visible within the first few months.

The enemies of Bianco Carrara

Acid: the biggest threat

Marble consists largely of calcite, a mineral that reacts chemically with acids. In a kitchen, acids are everywhere:

Lemon juice and vinegar: directly visible damage after prolonged contact
Soft drinks: cola, sparkling water, tomato juice
Wine: both red and white
Coffee grounds and tea: less aggressive, but cumulative
Some cleaning products: all-purpose cleaner, bathroom cleaner, soda

Acid damage on marble appears as a dull, lightly eaten-away patch on the otherwise glossy stone. We call this etch damage. One small drop of lemon juice that is not wiped away immediately can be enough.

Important: Etch damage is not a stain. It is damage to the surface itself. It cannot be wiped away; it requires mechanical polishing by a specialist.

Fat and oil

Olive oil, butter and herb oils can penetrate the pores of marble and leave dark stains. The longer the contact, the deeper the staining.

Water and limescale

In Amsterdam, the water is relatively hard. Water droplets that remain and evaporate leave limescale deposits behind. On polished marble, these appear as white, dull rings that disrupt the gloss.

Impregnation: the first line of defence

Before you start using your Bianco Carrara worktop, it should be impregnated. A good impregnator penetrates the pores of the stone and forms a hydrophobic barrier that slows the absorption of liquids and fats.

We work with BioShield: a solvent-free, deep-penetrating impregnator developed specifically for calcite-rich stones such as marble and limestone.

How often should it be impregnated?

New worktop: immediately after installation, before use
Repeat protection: every year, or sooner if the water absorption test shows it is necessary

Water absorption test: Place a few drops of water on the worktop. If the water is absorbed within 5 minutes and a dark mark appears, new impregnation is needed. If the water remains beaded on the surface, the protection is still active.

Please note: Impregnation does not protect against etch damage. It slows the penetration of fats and water, but acid attacks the surface directly regardless of impregnation.

Daily maintenance

Cleaning

Use warm water with a few drops of pH-neutral soap or a dedicated stone cleaner
Wipe with a soft microfibre cloth
Never use: vinegar, lemon cleaner, all-purpose cleaner, chlorine, soda or abrasive sponges
Dry the worktop after cleaning with a dry cloth; do not leave water standing

Daily habits that protect your marble

Use chopping boards: always, including when cutting meat and vegetables
Use coasters under glasses: also under water bottles and dairy products
Wipe acids immediately: remove lemon juice, vinegar and wine at once with a damp cloth
Never place hot pans directly on marble: use a trivet; thermal shock can cause microcracks

What should you do about stains?

Greasy stain (oil, butter)

Make a paste from talcum powder or corn starch and water. Apply it to the stain, cover with plastic film and leave it for 24 hours. The paste absorbs the fat. Repeat if necessary.

More stain types and treatments: removing stains from marble

Wine stain or coffee stain

Treat the stain with hydrogen peroxide (3–6%, available at a pharmacy). Apply it to a cotton cloth, place it on the stain and cover it. Leave it to work for several hours. Do not use this on dark marble.

Etch damage (dull patch after acid contact)

This is damage to the surface itself. Small, superficial etch marks can be temporarily improved with marble wax (Lithofin Marbec or equivalent), but the only real solution is professional polishing. Contact DecoStone.

Patina or pristine? The choice is yours

Many owners of marble kitchens have to make a conscious choice: do you accept the patina — the dull spots, etch marks and living character of the stone — or do you want to keep it as close as possible to its original condition?

Some architects and interior designers see the traces of use as a quality of marble: it becomes more beautiful with age, not less. Others prefer consistent maintenance with an annual polishing service.

Both choices are valid. DecoStone will be happy to advise which approach suits your use and your taste.

When should you call in a specialist?

Multiple etch marks or a large dull area
Deep oil or wine stains that do not disappear
Scratches visible in the surface
Joints that are coming loose or discolouring
The worktop simply no longer looks fresh

An annual maintenance service by DecoStone, including polishing, impregnation and joint replacement if needed, keeps your Bianco Carrara in good condition and significantly extends its service life.
