Review: Excellent value for anyone who uses deionised water regularly - Hexeal Deionised Water comes in a convenient 10L container, making it an excellent choice for various household and automotive needs. This demineralised water is specifically designed to be used in steam irons, car batteries, windscreen fluid, antifreeze, and laboratory applications. The key selling points are its ability to reduce limescale deposits, water stains, and the fact that it’s safe for a variety of uses. Here’s an honest review of its features, pros, and cons: What’s Great: Ideal for Steam Irons and Household Appliances: One of the standout features of Hexeal Deionised Water is how well it works with steam irons. Using deionised water in your steam iron helps prevent limescale build-up, ensuring that the iron continues to function smoothly over time. It can also help prolong the life of other household appliances like humidifiers or steam cleaners, making it an essential product for anyone who wants to keep their appliances in top condition. Perfect for Car Batteries and Antifreeze: Deionised water is recommended for topping up car batteries as it helps maintain the electrolyte levels without introducing impurities that could damage the battery. It can also be used in antifreeze mixtures, ensuring that the water doesn't cause unwanted mineral deposits in the cooling system. This makes it a versatile product for car maintenance. Reduces Limescale and Water Stains: The deionisation process removes minerals from the water that could cause limescale build-up, which is particularly useful in areas with hard water. Using Hexeal Deionised Water reduces the likelihood of water stains or limescale deposits in appliances, leaving them cleaner and extending their lifespan. This is especially noticeable with appliances like irons and kettles, which are prone to mineral build-up. Large 10L Capacity: The 10L container is a generous size, making it a cost-effective option if you’re using deionised water regularly. It provides plenty of water for multiple uses, whether you’re topping up car batteries, using it in appliances, or mixing it with antifreeze. This large quantity also means you don’t need to constantly repurchase smaller bottles, which can save time and money. Safe for Lab Use: Hexeal Deionised Water is marked as suitable for lab use, making it a reliable option for scientific experiments and applications where purity is important. The water’s purity ensures that no contaminants interfere with experiments or processes, which is a great feature for laboratories or those working with sensitive equipment. What Could Be Improved: Heavy and Bulky Packaging: While the 10L container offers excellent value, it can be quite heavy and cumbersome to carry, especially when it’s full. If you need to transport it regularly, you may find the size and weight a bit impractical. Some might prefer a more compact or smaller-sized option for easier handling, especially for those with limited storage space. Not Ideal for Drinking or Cooking: As deionised water has had its minerals removed, it’s not recommended for drinking or cooking, and it's important to keep this in mind. While this is true for all deionised water, some users may assume it’s safe for consumption. It would be helpful if the packaging had more explicit warnings to ensure users understand the appropriate uses for this water. Limited Use for Non-Specialised Applications: While the product is great for a range of specialised uses like car batteries, steam irons, and laboratory purposes, it might not have widespread appeal for general household use. If you don’t have any appliances or vehicles that require deionised water, you may not need such a large quantity, and smaller bottles may be a better fit. Noteworthy Observations: Cost-Effective for Frequent Users: The large 10L size makes this a very cost-effective option for those who frequently require deionised water. If you use it regularly in appliances, for car maintenance, or other uses, this bulk option will save you money in the long run compared to buying smaller bottles. Environmentally Friendly Option: By purchasing a larger quantity, you might find yourself reducing the need for single-use plastic bottles, making it a more environmentally friendly option. Some customers may appreciate this aspect if they’re looking to cut down on their plastic consumption. Verdict: Hexeal Deionised Water is a highly practical and reliable product, offering excellent value for anyone who uses deionised water regularly. Whether for maintaining household appliances, topping up car batteries, or mixing antifreeze, this 10L container is both convenient and cost-effective. It helps reduce limescale and water stains, prolongs the lifespan of appliances, and is safe for scientific use. While the large packaging can be cumbersome, and it’s not suitable for drinking or cooking, it’s a great option for specialised needs. If you’re looking for a good-quality deionised water for your appliances or vehicles, Hexeal is a solid choice that delivers great performance at a reasonable price.
Review: High Quality and Versatile Deionised Water - This deionised water is excellent quality and ideal for a wide range of uses, from car batteries and steam irons to lab work. It helps prevent limescale and water stains, and the 10L size is great value. A must-have for home, garage, or workshop.

## Features

- USE IN IRONS & MOPS IN HARD WATER AREAS TO ELIMINATE LIMESCALE BUILD-UP: Deionised Water reduces corrosion and eliminates limescale deposits, extending the life of appliances. Great for use in residential, commercial or industrial premises with hard water in areas such as the East Midlands, East Anglia, London and the Southeast of England. Replace tap water with Deionised Water in steam irons and steam mops to ensure no chalky marks or hard water stains are left on your clothing.
- ADD TO SCREENWASH FOR CRYSTAL CLEAR CAR WINDOWS: Deionised Water works wonders on windows and can be used to dilute Antifreeze or a windscreen wiper fluid, as it reduces build-up in mineral deposits that often sits on windscreens with standard screen washes. Deionised Water can also be used for topping up car batteries and engine cooling systems as well as in car detailing.
- DEIONISED WATER FOR LAB USE: Deionised Water can be used for lab applications. This is because accurate test results can be obtained due to knowing the purity of the water. It is also useful for cleaning lab equipment and sterilisation. Our high-purity Deionised Water has been formulated using our 'Ion Exchange Resin Bed Technology' plant-producing water, which is typically tested at less than 1-5 µS/cm with an accept point of 20 μS/cm.
- MAKE WINDOWS SPARKLE: Use around the home or on premises to reduce watermarks, stains, dirt and grime from main windows, conservatory windows, door windows and more to clean and improve visibility. Spray directly onto the window or add to a cloth to reduce streaks and stains left on windows.
