Softens water to boost the cleaning performance of your detergent Prevents spots and watermarks on dishes Contains no impurities such as iron and carbonates Product of UK Offers effective machine protection Product Description Finish pure dishwasher salt offers effective machine protection by softening water and helping to protect against limescale, whilst preventing spots from forming on your dishes. Since hard water deposits can quickly reduce the efficiency of a dishwasher, most machines are fitted with an in-built water softener. This salt helps to keep your machine's softener working so that limescale and watermarks are less likely to form. Finish dishwasher salt is specially granulated for dishwashers - the particles are larger than ordinary table salt so they dissolve more slowly and don't clog up your machine. Other salts also contain impurities like iron and carbonates that damage, rather than protect, your machine, while Finish dishwasher salt is 99.9% pure for maximum effect. Directions Directions: fill your water softener unit as directed by the dishwasher manufacturer. For best results check the salt level frequently and keep topped up with Finish Salt, particularly if you live in a hard water area. Safety Warning Important: other salts may contain impurities like iron and carbonates which will damage the water softening unit. Keep away from children Do not ingest. If product is ingested then seek medical advice.
