The statement that retainers should be cleaned after each meal is true, as maintaining proper oral hygiene is crucial for both the health of the teeth and the effectiveness of orthodontic treatments. Retainers can accumulate plaque and food particles, which can lead to bad breath, discoloration, and potential oral health issues if not cleaned regularly. Cleaning them after each meal ensures that bacteria and debris are removed, preventing any buildup that could pose health risks.

Regular cleaning also helps preserve the condition of the retainer, allowing it to fit properly and function effectively. Other options do not sufficiently emphasize the importance of regular cleaning; cleaning once a week or only when soiled does not account for maintaining optimal hygiene. Soaking in mouthwash could potentially damage the retainer material or cause it to wear down over time, making this option unsuitable for proper care.
