The details

Hard water can leave dishes looking dirty even after several dishwashers runs. Using dishwasher detergents equipped with water softeners counters the problem. The Finish Hard Water Booster Powder not only softens the hard water but it also removes white film and spots on your dinnerware.

Cleaning power

The product is used along with dishwashing detergents to remove stains on dishes when using hard water containing minerals like chalk, silt, manganese and limestone. You can add the product directly at the bottom of the dishwasher or dispense it through the pre-fill chamber.


Since the detergent is only used as an additive to soften water, it hardly leaves any residue on glass plates and cutlery. However, you want to avoid using it on plastic dishes as it leaves a milky residue.

Additional cleaning features

The product isn’t only formulated to soften hard water; it can get rid of film stains and any residue buildup on glassware.

Value for money

While the product is only used as an addition to regular dishwasher detergents, its features would give even the best dishwasher detergents a run for their money. This is because it can also remove stains, limescale buildup, and film.

Final verdict

The product is an excellent boost for your regular detergent if you live in areas with hard water. It softens the water and removes any stains that may have developed over time. If you’re worried about the foul odor that comes with the white chalky substance, the product leaves a refreshing lemon scent.
