Ocado Dishwasher Salt Granules.Dishwasher salt is an essential ingredient for maintaining the efficiency and lifespan of your machine. Designed with coarse crystals, this salt works by softening hard water, which is crucial for preventing the build-up of damaging limescale on internal components and heating elements.Using this salt regularly ensures that your machine runs at optimum performance. By neutralising the hardness of the water, the softened water allows your dishwasher detergent to work far more effectively, resulting in a superior cleaning performance and prevention of the cloudy film, white spots, and streaking that can ruin the finish on your glassware and cutlery.This large 3kg pack provides excellent value and long-lasting protection for your appliance. It's also suitable for water softeners.From bleach to bin bags to bathroom cleaner and everything in between, we've got what you need to fill up that cleaning cupboard under the sink, simply search 'Ocado household'.
