Viakal Limescale Remover Marble Bathroom Stains

We’ve been working for many years in the marble industry and worked on all types of natural stone, however, the one job we most work on tends to be the removal of Viakal stains from marble showers. 

It’s caused when using Viakal limescale remover to remove limescale around taps and showerheads. If you are not careful when cleaning these, the Viakal can easily stain the marble in your bathroom or shower.

Many cleaners tend to leave the Viakal limescale remover spray on the surface to eat away at the limescale, but unfortunately it also eats away at the marble too. 
The good news is that we have seen a lot of success in removing Viakal stains from marble and the end result usually looks very close to new. 

But you will need to call in a professional for this type of job because it does require special tools and expertise.

If you're a homeowner, then don't worry! We offer our professional services to homeowners on all budgets and with no obligation quotations that can be discussed over the phone or via email before any work commences.

Why does Viakal Limescale Remover Stain Marble?

As you can see from the Viakal limescale remover safety data sheet, Viakal has 3 types of acid in it, Formic acid, Deceth-8, and Citric acid, none of which are very good for marble as you can imagine.

These acids are designed to breakaway limescale, the problem is, it also burns, or etches into the marble, leaving pale white burn marks. 
These can look terrible and almost unsolvable! However, there is a way to remove these Viakal marble shower stains. 

This is because marble has a very high water absorption rate which means that the acid can penetrate deep into the pores of your marble, causing more damage than usual.

What are my options? How do I remove limescale without affecting the marble?

There are many good sprays at removing limescale, but none that are good on natural stone tiles. 

If you need to remove limescale from your shower walls or bathroom floor then there are two ways:
1. The easiest way is using fine wire wool to remove the limescale from the surface.
2. If the wire wool alone doesn't work, use natural stone soap to help eat away at the limescale before using the fine wire wool to break up the limescale.

How to safely remove Viakal bathroom stains

To remove the Viakal limescale remover spray burn marks on marble shower tiles, we use a diamond pad to grind away and polish up until all stains are removed. 

We tend to use around 4-5 pads for this process depending how badly stained your walls may be. Once it is done you can seal the wall with an acid resistant primer that will protect any remaining tile from future damage!

Depending on how badly stained the marble tiles are in the shower wall, we use a more abrasive pad until the stains are removed. We then move onto a finer diamond pad until the wall is completely honed and sealed. 
We tend to use between 4 or 5 pads to ensure all the Viakal stains have been removed from the shower walls. Once the wall has been repaired, we will grind back to its original color and seal and polish it so that the area looks new.

Viakal Limescale - Viakal is a type of limescale remover used primarily to remove hard water stains from around taps and showerheads. It's acidic in nature, so if you're not careful it can easily stain the surface on which it has been applied. 

The good news is that we have seen success with removing Viakal stains from marble, but we would recommend contacting a professional if you are not sure how to go about it.

How to protect your marble after the removal of Viakal marble shower stains

Once we have removed the Viakal limescale remover shower stain, it’s important to look after your marble tiles as much as possible. For starters, keep Viakal limescale remover away! If you want to keep limescale away, it’s important to ensure the bathroom remains as dry as possible. 
Use a squeegee after you use the shower to dry away any water droplets that may remain on the marble tiles. Only use a neutral detergent (Fairy washing up liquid is an example of a neutral detergent) to help clean the tiles to remove any soaps or liquids that may have splashed onto the walls during your shower.

Final Thoughts on Viakal Limescale Remover

Viakal limescale remover is a very abrasive cleaning product. It should never be used on any natural stone surface. The acid in the product will eat away at the stone and leave a horrible looking white burn mark.

Unfortunately there is no simple option to remove these stains. You must call a professional stone renovation expert. We will need to use diamond pads to sand back the surface until the burn and etch marks have completely disappeared. Then we can hone, seal and polish the area to bring back the natural colours.

Use there products to clean, seal and maintain your marble:
Lithofin Easy Clean - For easy maintenance and to clean away any grime.
Lithofin Stain Stop - This product will seal the pores in your natural stone and prevent water damage. You can use this once a month with a dry cloth.
Fine Steel Wool - This product is excellent for removing any residue that is on your surfaces, like limescale. Only use the "Fine" steel wool, any other grade will be too abrasive and could scratch your stone.
Don't forget you can call us anytime if you have any questions or concerns about how to remove Viakal Stains from your marble surfaces.
