Using plastic liners in garbage cans is an effective way to keep them clean and free of buildup. These liners create a barrier between the waste and the can itself, preventing food particles and liquids from sticking to the interior surfaces. This makes it easier to clean the cans and reduces the risk of unpleasant odors and contamination from spills. Additionally, when the liner is full, it can be taken out and disposed of, minimizing contact with the waste and keeping the can cleaner.
Other options, such as leaving the lids open, would expose the contents to air, potentially leading to odors and attracting pests. Emptying them less frequently could lead to overflow and increased mess, while allowing garbage to sit for days would contribute to buildup and hygiene issues. Using plastic liners effectively addresses all these concerns, promoting better sanitation practices in food service environments.
