What is marble etching and how can you prevent it?

At RSC, customers often ask us about marble etching. So, here, we take a look at what it is and how you can avoid it. After all, few substances have marble’s natural elegance, so it’s understandable that you want to keep your stone looking its beautiful best.

At Royal Stone Care, we often get pleas for help from customers who have inadvertently used a regular bathroom, kitchen or sink cleaner on marble or a similar natural stone. The marble has then ‘etched’, or developed dull spots on its surface.

That’s because not all types of cleaning products will be good for sensitive natural stone surfaces such as marble.

In the worst case scenarios, these products can do more harm than good and actively damage your countertop or bathroom surface.

What is it?

Etching is physical damage to your marble. It happens when certain substances come into contact with the stone. These could include coffee, wine or other alcoholic liquids plus citrus and fruit juices.

It’s not the same thing as staining. Etching is a corrosive reaction in the stone. It takes off the marble’s top layer to show the raw stone underneath it. So it’s as though you have burned off that layer. The area you can then see is duller and lighter than before.

Etching shouldn’t be confused with staining. It’s more of a permanent alteration of the stone itself, in the same way a scratch would change it. And it’s more of a dulling than a discolouring.

In contrast, a stain happens when the stone discolours after a liquid seeps into and penetrates your marble.

How can I prevent this?

Good news! As ever, prevention is better than cure. And there are a number of things you can do to minimise the risks of etching. These include:

  1. Using a quality marble sealant to reduce the marble’s porosity – if you wipe up spills promptly, etching is far less likely
  2. Clean up acidic spills with a damp cloth right away
  3. A honed finish reduces visible etching so consider for ‘busy’ areas of your kitchen and if you have a busy household
  4. Use coasters and chopping boards as much as you can
  5. Only use cleaning products specifically designed to use on marble – many multi-purpose products are actually acidic
  • Whatever product you are using, test it out first on a small, discreet area
  • Mop up any spillages straight away to avoid leaving a permanent mark
  • If you do get etching, or the marble otherwise reacts badly to a cleaning product, talk to a natural stone specialist
  • Do NOT use any products containing any of the following: bleach, ammonia, vinegar or hydrogen peroxide, lemon or anything else acidic on marble
  • Abrasive cleaners or pads are also likely to be too harsh for natural stone

Try and stick to a mild natural detergent or specialist marble cleaner.

Is it possible to reverse marble etching?

Unfortunately, no, not really. It’s hard to reverse marble etching once it’s happened. After all, it’s a chemical reaction. You could try some polishing products that are on the market. But, in truth your marble will never look quite the same again.

It’s true that you may only be able to see slight marble etching in some lights. And it certainly doesn’t have to be the end of the world. But it’s damage to your marble. It’s not a cheap stone, particularly, and so you will want to sort the problem out.

A professional marble cleaning firm will sand down the whole surface before refinishing it.

For serious stains, etching or for marble chip repair, you are almost always better off talking to a natural stone specialist.
