The plastic wrap on dishwasher detergent capsules is a water-soluble film designed to contain and protect the detergent inside. It dissolves and disperses in water during the dishwasher cycle.
When using dishwasher detergent capsules, you typically place the capsule directly in the dishwasher detergent dispenser or simply drop it into the main compartment of your dishwasher. The plastic wrap will dissolve in the water and release the detergent to clean your dishes.
It's important to note that different dishwasher detergent capsules may have specific usage instructions, so it's advisable to follow the directions provided by the manufacturer on the product packaging to ensure optimal performance and cleaning results.
