What happens to film that is improperly washed after processing?

Film that is improperly washed after processing will turn brown with age due to the presence of residual chemicals, particularly the developer and fixative, which can remain on the film's surface if it is not adequately washed. When the chemicals are not thoroughly removed, they can cause oxidation and degradation over time. This deterioration manifests as a brown staining on the film, commonly referred to as "silver mirroring," which can ultimately reduce the quality of the images and their diagnostic utility.

In contrast, properly processed and washed film maintains its clarity and quality, making proper washing critical to the longevity and usefulness of dental radiographs. Other options describe different outcomes or changes that can occur under separate conditions, further highlighting the importance of adequate processing to avoid aging-related damage to the film.
