Which of the following is a good cleanser for a dishwasher?

Baking soda is an effective and gentle cleanser for dishwashers because it helps eliminate odors and can assist in loosening grime and buildup without damaging the appliance. It is non-toxic and safe for both the dishwasher and the dishes cleaned within it.

Similarly, powdered lemonade mix can serve as a cleanser due to its citric acid content. Citric acid is known for its ability to cut through grease and mineral deposits, making it effective in cleaning tasks, including those in a dishwasher. The acidity helps break down the residues that can build up over time.

Both options A and C provide natural cleaning actions that are safe for use in dishwashers, making them suitable choices together. Thus, the selection of both baking soda and powdered lemonade mix as good cleansers reflects their effective cleaning properties while ensuring safety for the appliance and the dishes.
