Viakal 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 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.

Viakal Marble Shower Stain Removal

Why does Viakal stain marble?

As you can see from the Viakal safety data sheet below, 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 shower stain, it’s important to look after your marble tiles as much as possible. For starters, keep Viakal 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.

Can you leave Viakal overnight?

Viakal is designed to be used in the shower, so it’s best not to leave this product on for too long as leaving it longer than a few minutes could cause damage. The manufacturer recommends that if you need to use the product over night then ensure that your marble has been sealed with an acid resistant sealer first.

How long can you leave Viakal on for?

The manufacturer recommends that it is best not to use the product over night, but if you do then ensure that your marble has been sealed beforehand. It should be applied to a dry surface and left alone for up to 20 minutes before rinsing it away with a water jet.

What do you use Viakal for?

Viakal is designed to remove limescale from your bathroom or kitchen surfaces. Do not use it on marble and other natural stone tiles in your home, such as granite or slate, as it contains phosphoric acid which will dissolve the mineral deposits that cause stains on surfaces like these, affecting the natural stone.

What is Viakal?
