How to clean a marble mortar? A quick and easy guide.

A good marble mortar will last for years , but only if cleaned properly. Understanding how to clean a marble mortar means protecting a precious stone, avoiding permanent stains, and preserving its natural beauty over time. The principle is simple: treat it gently , respecting the marble's characteristics.

Why marble is delicate

Marble is a natural stone made of calcium carbonate, making it sensitive to acids . Lemon, vinegar, wine, and harsh detergents can corrode the surface, dulling it, and creating difficult-to-remove stains. It's also a slightly porous stone: it tends to absorb some of the liquids and oils it comes into contact with. This is why, when choosing a Carrara marble mortar , it's also important to learn how to care for it properly.

How to clean marble mortar step by step

After using it, the first thing to do is immediately remove any residue : use a soft spatula or a spoon to remove the bulk, without using sharp metal blades.

To wash marble correctly, all you need to do is:

– rinse the mortar with warm water ;
– add a small amount of neutral soap (such as Marseille soap) to a soft sponge;
– gently rub the inside and outside, without using the abrasive side;
– rinse with plenty of water, until no traces of soap remain;
– dry immediately with a soft cloth , without leaving it dripping for a long time.

It's important not to leave the mortar soaking for hours: standing water can penetrate the stone and, over time, cause stains or small cracks. A quick and thorough cleaning immediately after use is the best way to preserve marble.

What you should never do when cleaning marble

As for maintenance, there are some golden rules:

– no vinegar, lemon or acidic detergents : they risk discoloring and dulling the marble;
– no aggressive degreasers or abrasive products : they could scratch the surface;
– no dishwasher : high temperatures and strong detergents are not suitable for marble or the wooden pestle.

These tips apply to both your marble mortar and otherCarrara marble objects you keep in your kitchen.

Stains and patina: it's part of the mortar's life

Even with all the care, marble remains a natural stone: over time, it may stain slightly or darken in some areas, especially if used frequently with oils, herbs, and spices. This isn't a defect, but rather the sign of a living object, working in the kitchen alongside you.
