Can You Use Tap Water in a Steam Iron?

It’s that time of the week again, the washing basket is stacked high with things to iron and you forgot to put deionised water on the shopping list. Ironing is a household chore that often requires little thought – until it comes to choosing the right water for your iron. Many opt for the convenience of tap water, but in the UK, where 60% of the population lives in hard water areas, this seemingly harmless choice can have consequences. So is tap water safe for irons? Let’s explore the impact of tap water on irons, and also the drawbacks of using deionised water, and discover a smart solution offered by Halcyan Water Conditioners.


Tap Water and the Hard Water Dilemma

Tap water is a readily available choice for filling your iron, but its composition can vary significantly depending on your location. In the UK, a majority of residents grapple with hard water, characterised by a high mineral content, predominantly calcium and magnesium. While harmless for consumption, these minerals can wreak havoc on your iron and clothes.


Hard Water and Limescale

One of the primary issues with using tap water in irons is the formation of limescale deposits. As hard water is heated in the iron’s chamber, the minerals accumulate on internal components. Over time, this buildup can clog the iron’s steam vents and heating element, reducing its efficiency and shortening its lifespan. Moreover, the presence of limescale in the steam can leave stubborn marks on clothing, presenting an additional concern.


The UK’s Hard Water Predicament

In the UK, navigating the hard water predicament becomes crucial due to the prevalence of these mineral-rich waters. Residents must consider alternative options to mitigate the adverse effects of hard water on their irons, safeguarding both their appliances and their favourite clothes.

The Deionised Water Dilemma

In response to the challenges posed by hard water, some individuals turn to deionised water as an alternative. Deionised water goes through a process of ion exchange, where the minerals responsible for the formation of limescale are replaced and you are left with purified water. While it may seem like an ideal solution, there are drawbacks to consider.

Aggressive Nature of Deionised Water

Deionised water, though lacking the minerals found in tap water, is not the perfect choice for irons. Its use can lead to corrosion of internal components over time. This corrosion may result in damage to the iron’s heating element and other crucial parts, compromising its functionality and longevity. Many manufacturers recommend the use of a 50:50 ratio for tap water and deionised water to attempt to balance out the issue.

Cost and Environmental Impact

Additionally, the ongoing cost of purchasing deionised water and the environmental impact of producing and disposing of plastic bottles may deter environmentally conscious consumers from choosing this option.


Halcyan Water Conditioners: A Smart Solution

Amidst the challenges posed by tap water and so-called ‘iron-friendly’ alternatives, there emerges a smart and effective solution – Halcyan Water Conditioners.

Understanding Halcyan Technology

Halcyan devices utilise advanced technology to treat water at its source. By employing a unique blended alloy, Halcyan’s internal structure of turbulence-producing fins and gateways alter the behaviour of minerals in the water, reducing the formation of limescale deposits. In short, nothing is added or taken away. The conditioned water that comes out of your taps not only benefits your iron but also extends to other household appliances and plumbing fixtures, providing a holistic solution to the problems associated with hard water.

How to Achieve Brilliant White Clothes: Tips for Whiter and Brighter Laundry

There’s something incredibly appealing about crisp, white clothes that exude freshness and cleanliness. However, maintaining the pristine whiteness of your garments can be quite a challenge, especially with stubborn stains and everyday wear. There are several causes of dull white clothes including stains, dye transfer and hard water. Fear not! In this blog, we’ll share some tried-and-true methods to help you achieve brilliant white clothes that look brand new, ensuring your wardrobe stands out with brightness and allure.


Separate Whites from Colours

The first step to keeping your whites dazzling is to sort your laundry meticulously. Separate white garments from coloured ones to prevent colour bleeding. Washing white clothes separately avoids the risk of coloured dye staining your whites, preserving their pristine appearance for longer.



Pre-Treat Stains

Tackle stains promptly to prevent them from setting in. Pre-treat any stains on your white clothes by applying a small amount of stain remover or liquid detergent directly to the affected area. Gently rub the fabric together to work the product in, and then let it sit for a few minutes before washing.


Use the Right Laundry Detergent

Choosing the right detergent is essential for whiter clothes. Opt for a high-quality laundry detergent specifically designed for whites, preferably one with bleach or enzymes that target stains. This will help break down tough stains and keep your whites looking brilliant.


Add Boosters

Enhance the whiteness of your laundry with boosters. White vinegar and baking soda are eco-friendly options, or oxygen-based bleach can work wonders when added to your regular detergent. These boosters help lift stains, brighten fabrics, and neutralise odours, leaving your whites fresher than ever.


Sun-Dry Your Whites

An eco-friendly solution is to harness the power of the sun to naturally bleach and whiten your clothes. Sunlight has natural bleaching properties that can help remove stubborn stains and maintain the brightness of your whites. Hang your white garments outside on a sunny day for an planet-friendly and effective brightening boost.


Avoid Overloading the Washing Machine

Overloading the washing machine can prevent your white clothes from getting a thorough clean. Ensure there is ample space for water and detergent to circulate freely, allowing for better stain removal and overall cleaning.


Use Warm Water

When washing whites, opt for warm water instead of cold. Warm water is more effective at dissolving stains and removing dirt, resulting in brighter and cleaner clothes.


Regularly Clean Your Washing Machine

A clean washing machine contributes to whiter clothes. Over time, residue from detergents and fabric softeners can build up inside the machine, affecting its cleaning efficiency. Clean your washing machine regularly by running an empty cycle with vinegar or a washing machine cleaner to remove buildup and ensure optimal performance.


Install a Halcyan Water Conditioner

Protecting your washing machine from the damaging effects of hard water is essential to ensure its longevity and optimal performance. Hard water, which contains high mineral content, can lead to limescale buildup and reduce the efficacy of your washing machine. If you live in a hard water area, you might be surprised to learn that limescale can cause your white clothing to become dull and stained over time. By installing a Halcyan Water Conditioner, you can ensure that your washing machine is free from limescale and your whites stay bright and clean after every wash!



Keeping your white clothes white is no longer an elusive task with these simple yet effective tips. By separating whites from colours, pre-treating stains, using the right products, sun-drying your garments, and maintaining your washing machine’s cleanliness, you can achieve brilliant white clothes that radiate freshness and elegance. With a little care and attention, your whites will look brand new for longer. Say goodbye to dingy whites and embrace the brilliance of your freshly laundered, white garments!
