This product is highly effective and very concentrated. Simply fill up your dishwasher's finishing agent reservoir as needed (typically once a week, depending on how often you use your dishwasher) Why use our rinse aid? We're proud of the formula we created, here's why: Rinse Aid reduces the surface tension of the water inside your dishwasher. This makes water less likely to cohere in drops on your dishes- meaning virtually no spots on your dishware! As above, rinse aid also makes your dishes finish drying faster, which allows the dishwasher to use less power each cycle, making every load of dishes you run with Rinse Aid more eco-friendly! No toxic residue left behind on clean dishes- unlike the leading finishing agent brands 100% Free of Toxic Gick Found in Other Dish Finishing Agents: NO SODIUM HYPOCHLORITE [ High Concern: acute aquatic toxicity; Moderate Concern: respiratory effects ] NO CHLORINE [ Some Concern: respiratory effects, general systemic/organ effects, skin irritation/allergies/damage, damage to vision ] NO CARBON TETRACHLORIDE [ Some Concern: general systemic/organ effects, cancer ] NO 1,1-DICHLOROETHYLENE [ Some Concern: kidney and urinary effects, general systemic/organ effects, cancer ] NO HYDROZINCITE [ High Concern: acute aquatic toxicity, chronic aquatic toxicity; Moderate Concern: general systemic/organ effects ] NO ARTIFICIAL COLORS [ High Concern: Government enforceable restrictions; Some Concern: general systemic/organ effects, developmental/endocrine/reproductive effects ] NO SODIUM TRIPOLYPHOSPHATE [ High Concern: general ecotoxicity; Some Concern: respiratory effects, skin irritation/allergies/damage, damage to vision ] NO ANTIFOAM [ Some Concern: respiratory effects, general systemic/organ effects; Some Concern: developmental/endocrine/reproductive effects, damage to vision ] NO PHTHALATES NO PHTHALATE-BASED FRAGRANCES [ Some Concern: respiratory effects, developmental/endocrine/reproductive effects ] NO ACRYLAMIDE
