Calgon 2in1 water softener gel helps protect and clean your washing machine, so it can work at its best for cleaner laundry every wash and no bad smells. It contains active polycarboxylates which soften hard water and prevent potentially damaging limescale deposits from forming on the inside of your washing machine, helping it to work better and for longer. As Calgon gel is purely a preventative measure and not a descaler, it should be added to every wash to help keep your washing machine clean and free from limescale. So, the sooner you introduce it into your daily washing routine, the better. Simply add 1 - 1 2/3 caps into your dispenser drawer on top of your normal washing detergent, and it will get to work as soon as the water begins to flow. It can be used with any wash programme and on any type of fabric, and could even save you up to 25% on your detergent bills, as you only need to use the amount recommended for soft water. Less limescale also means less energy consumption: with regular use, Calgon water softener can help keep your carbon footprint that little bit smaller.
