Limescale: What is it and how to prevent its build-up:

Limescale build-up throughout your home and water networks can be a headache for many homeowners. Limescale can break utilities, damage cutlery and clothing and lead to further damage to pipes and faucets.

But how can you notice limescale build-up, where should you most commonly check and what can you do about it? That is something we are going to address here. 

What causes Limescale:

Limescale is the deposits left behind by water with a high mineral count. Most common is calcium carbonate which leaves appliances with a hard caulk like substance in, on and around most appliances that use hot water.

Limescale is found throughout Ireland as our water has high mineral content. This means most homes and businesses will at some stage face some issues with limescale.

Where will you find limescale:

As we have stated already limescale is found in many appliances, taps and faucets that use hot water. The most common areas that you will find unsightly limescale include kitchen sinks and taps, dishwashers and washing machines and bathroom showers and sinks.

When left untreated limescale build-up will affect bathtubs, shower curtains etc leaving a distinctive whitish chalk-like substance.

What problems does limescale cause:

Limescale should not affect the health of your family or visitors, however, it is damaging in other ways.

Limescale reduces water flow to your appliances meaning they will not function properly. In other instances, larger build-ups will damage your washing machines and dishwashers. 

Adding additional cost to repairs and replacements.

How to remove Limescale:

Limescale build-up should best be prevented than cleaned, but if it is too late, that there are a few steps that you can follow to remove limescale.

There are a wide variety of chemical and natural solutions to help remove limescale including vinegar and lemon juice. It’s always a good idea to check your local supermarket for quality cleaning products.

  • Always ensure they are out of the reach of children.
  • Follow instructions on shop-bought products or follow the instructions of friends who have had similar issues. 
  • Another great option is to simply look online for both natural and readymade limescale removal solutions.
  • Often you will need a few hours or an overnight wait to completely remove limescale from your taps and faucets.

Preventing limescale:

As already stated, limescale prevention is far better than cleaning. You will save on repair and replacement cost for much of your appliances and you will save time regarding cleaning if limescale never builds up.

But how should you do this?

For new homes, it is far easier to prevent limescale build-up as you can install numerous devices and preventive measures before use. 

Thankfully for older homes, many of these devices can be easily installed in existing mains and pipes.

How Limescale is costing your business money:

As a business owner, of all the expenses that you have for your business, we are quite sure that Limescale does not make your list.

This chalky white substance may not seem like a big deal, however, with a large build-up over many years there are quite a few ways that Limescale can be affecting your business. We are going to have a look at how Limescale may be hurting your business, both in terms of cost and reputation and what solutions you can make.

4 ways Limescale is affecting your business:

Each one of these effects on your business can lead to the other and it is hard to tackle each issue. We recommend prevention rather than reaction, but how does limescale affect your business?


Customers who use your facilities want clean and fresh look appliances and utilities. Having limescale on hotel showers, restaurants bathrooms and bar sinks can leave customers feeling a little icky.

Heavy mineral deposits in water stain appliances throughout the year. Irish Water has a heavy mineral content meaning it is a constant battle to clean.

Having a reputation as a business that doesn’t look after their basic facilities may result in customers not visiting your establishment.


To offset having a bad reputation, businesses then must fork out extra money on cleaning services to make their facilities pristine. 

As limescale cleaning can take quite a while this will eat into your finances. Though not a major issue at first, over months and years, labour and cleaning product costs add up. 


Most likely the biggest expense you will have with major limescale build-up is the cost of repairing and replacing appliances and associated plumbing costs.

Large limescale build-up can adversely affect dishwashers, washing machines, kettles and any other appliance that uses hot water regularly.

Constant use will likely lead to damage. These machines will need to be repaired or replaced.

Limescale build-up in pipes leads to lower pressure and worse functionality. To help with this you may need to hire a plumber, not a cheap expense especially for something preventable.

Energy costs:

The best-case scenario for your appliance that does not break with limescale build-up is a reduction in its use and power output. 

Washing machines and dishwasher will have to use more electricity and ultimately increase your energy costs over time with limescale build-up.

If you are a large restaurant or hotel using machines constantly this will greatly exacerbate your energy bills over the years.

Reducing overheads should be a top priority and with increasing fuel bills, energy costs will continue to rise unless you do something about it.

How to prevent Limescale build-up

Now that we have seen just a few ways that limescale can affect your Irish business, what can you do to prevent it?

Thankfully, there is a device that can remove limescale from your water system. This device reduces your costs and does not require much maintenance or energy to run.

Limescale, what is it and how do you get rid of it?

We often hear about Limescale and ways to get rid of it from our water systems and appliances, but how many of us know what limescale is and the damage it can cause?

Buying a product without truly knowing its purpose can sometimes lead to even bigger bills in the future.

So, let us have a brief look at what Limescale does, its harmful effects, and the best way to prevent its build-up in your home or office.

What is Limescale?

Limescale is the white chalky stuff you may have found on your taps and sinks or inside old homes, homes that didn’t have the benefit of today’s technology.

It is Calcium carbonate which has been broken down from hard water. Hard water is that which we receive in our taps, high in salts and other minerals. Many of which are positive to us and our bodies and others which are a little nastier.

Limescale is not physically harmful to us, but it can be frustrating. 

The effects of limescale on your home

The chalky white (or brown) stains:

Limescale builds upon water resources such as taps, showers, and toilets can give your bathrooms an aged and dirty look. Discoloration can stain your sinks and toilets creating additional expenses you don’t need.

Limescale in appliances:

Warmth and hard water are a perfect combination for destroying your home appliances. Therefore, many adverts highlight the damage done to washing machines, dishwashers, and kettles. Limescale build-up can slow down the efficiency of your appliances and completely break them down over time.

Staining of clothes and dishes is another after-effect of Limescale. A slow but corrosive substance, it’s better to prevent Limescale than to deal with the after-effects.

Build up within pipes:

One of the most frustrating issues caused by limescale is its slow build-up in your water network. This can lead to complete blockages, leaks, and the waring down for your pipe network.

Appliances and bathroom features can be replaced, but calling in plumbers for bigger problems can be even more costly and time-consuming.


How to stop limescale in its tracks (We mean pipes) 

Due to the problems posed by Limescale, there have been new and emerging ways to tackle the problem over the years and we have tried and tested many of them.

Dropson Limescale Preventers are the best way to get rid of Limescale before it can cause any damage to your systems, but who are Dropson and what does a limescale preventer do?

Top Tips for Preventing Limescale

Hardness is a typical property of water, with benefits for your body. It will increase your intake of calcium and magnesium which in turn may help protect against high blood pressure and cardiovascular issues.
However, when heated, the calcium component of hard water can result in limescale. This can be detrimental to household appliances such as kettles, dishwashers, washing machines, and some heating systems.
Depending on the interaction of other factors, such as pH and alkalinity, water with hardness above approximately 200 mg/l CaCO3 may cause scale deposition.

So what can you do?


Try to boil only what you need and don’t leave the surplus boiled water lying in the kettle. Kettles can be descaled by half-filling with half water/half vinegar, leaving overnight, rinsing, refill and boil water, then discard water and the kettle is ready for use. Descaling kits are widely available in supermarkets.

Washing Machines

A wide range of products are commercially available (e.g. Calgon) to prevent the deposition of limescale during the heating of water in washing machines. Varying the dosage of washing powder may also work.

Heating Systems

Indirect heating systems where water is re-circulated are generally not affected by limescale. Direct heating systems, where freshwater replaces heated boiler water, may experience some blockage of pipes and reduced boiler efficiency. Symptoms of this would be rattling in the pipes when the water is heated, and gradually longer heating times. Consult a plumber if such problems are suspected.


Dishwashers generally have built-in water softeners. Householders should ensure these are set according to the manufacturer’s instructions.

Shower Head

If limescale has built up – soak the showerhead in half vinegar/half water solution for three hours or overnight to remove the limescale. Descaling kits are widely available in supermarkets.

Soften the entire Water Supply?

Chemically softened water is not suitable for everyone to drink – particularly for infants and other risk categories.
Hard water can be “softened” by chemically removing calcium (by ion exchange) from the water and replacing it with sodium chloride or potassium chloride.
With Dropson, you can eliminate the use of salt altogether.
The Dropson Limescale Preventer prevents limescale buildup throughout your plumbing system and so will preserve plumbing appliances.
It will save you money on water heating bills, and reduce energy use in your home as it uses the same amount of energy as a 40 W energy saving light bulb.

The Dropson Limescale Preventer requires no maintenance and comes with a 5-year warranty on all parts.
