ᐅ How do I remove limescale from Malm surfaces after water damage?

Hello everyone,

I recently discovered heavy limescale deposits and stains on a Malm surface (specifically on a sideboard from this series) following water damage. The surface is made of MDF with a special coating that is said to be sensitive to aggressive cleaning agents.

My question is: How can I effectively and gently remove limescale deposits or buildup from Malm surfaces? Are there any proven products or methods that protect the coating while removing the limescale marks?

It is important to me that the surface does not become dull or damaged, as I want to preserve the piece of furniture as much as possible.

Thanks in advance for your tips and experiences!

It’s really frustrating when water and limescale leave marks like that.

I once had a similar issue with a lacquered piece of furniture after water damage. What helped me somewhat was a mixture of lukewarm water and a few drops of dish soap, applied gently with a microfiber cloth.

But I completely understand your concern about the sensitive surface—harsh cleaners are definitely not an option there.

Maybe try a gentle cleaning first and see how the surface responds.

How long have the limescale marks been there? That can also affect how difficult they are to remove.

I would not recommend vinegar or citric acid for lacquered furniture, as they often damage the surface seal.

Mild cleaners and plenty of water are the way to go. Afterwards, make sure to dry thoroughly.

Do not use overly aggressive cleaners for descaling.

Limescale stains can often be removed with a damp cloth and a mild scouring pad, but be careful.

I would like to add that special attention must be paid to the coating on Malm surfaces.

Aggressive acids such as acetic acid or citric acid can damage the coating.

There are special cleaning products for delicate furniture that remove limescale without corrosion – for example, cleaners with mild phosphoric acid or approved plastic cleaners.

Always test the product in an inconspicuous area before use.

Hello Nonudi,

From my experience, cleaning lime deposits on painted surfaces should be done gradually.

1. Try warm water and dish soap first, as Joe52 described.

2. If that’s not enough, sometimes a sponge with a mild abrasive side can help – but be very gentle and don’t use it too often.

3. I would really avoid products containing citric acid or vinegar because of the paint.

4. For stubborn spots, I recommend special furniture cleaners.

Additionally: After cleaning, be sure to dry the surface thoroughly to prevent new lime buildup.

I hope this helps. Be patient, and your furniture will stay looking good for longer.
