To make sure you are effectively preventing limescale in your dishwasher, regular maintenance of your appliance, and proper use of cleaning agents are vital. Limescale, a chalky residue from hard water,(1) can build up over time, affecting your dishwasher's performance, longevity and the cleanliness of your dishes. Here are some expert tips to help keep your machine free from limescale:
- Use dishwasher salt: One of the most reliable methods for preventing limescale is to use dishwasher salt, such as the Finish® dishwasher salt, especially if you live in an area with hard water. Does dishwasher salt prevent limescale? Yes - it softens the water by neutralising calcium and magnesium, the minerals that cause limescale.(1)
- Regular cleaning cycles: Run your dishwasher with a dishwasher or limescale cleaner, such as the Finish® dishwasher cleaner, on an empty cycle once every 3 months. This will help dissolve any existing limescale build-up.
- Check the water hardness: If your dishwasher has a water softening system, it will need to be adjusted based on the hardness of your water. You may need to consult your local water authority to determine this.
