Lemi Shine\'s Dish Detergent Booster is the top selling dish detergent booster, known best for removing the toughest hard water spots and film. More often than not, hard water is the culprit leaving tough spots and film on your dishes. Lemi Shine Dish Detergent Booster is a dish spot remover that fights back against the minerals in hard water (magnesium and calcium) to give you clean dishes. Use with your dish detergent in every load to give your machine a boost and make spots and film disappear. Booster\'s versatility goes far beyond the dishwasher. Supercharged with citric acid, it can be used to clean water bottles, descale kettles, refresh humidifiers and diffusers, or dissolve buildup on faucets and showerheads. You can even use it to refresh your rusty garden tools. From everyday kitchenware to more creative DIY tasks, Lemi Shine delivers powerful results wherever you need it. Use as part of the Lemi Shine Full Dish Regimen: Place one Lemi Shine Detergent Pod into the main wash receptacle. For best results - especially in hard water areas - add Lemi Shine Dish Detergent Booster to the prewash receptacle. If your dishwasher has only one receptacle, place detergent directly in the bottom of the machine. For a sparkling finish, add Lemi Shine Rinse Aid during the final rinse cycle to help prevent spots. Finally, start dishwasher as normal.
