Check the exact model's owner instructions and parts diagram. Some baffles are designed for owner removal, while a similar-looking rubber piece on another disposer may be retained as part of the assembly.
What the observation tells you
Pulling on an unfamiliar seal can damage it or disturb the mounting. Do not infer removability from a cleaning video or from the fact that one edge lifts. Safely isolate the appliance before any approved accessory handling and never reach into the chamber.
A useful next step
If removal is permitted, follow the specified method and cleaning materials. Otherwise clean only the accessible surfaces as directed or have the part attended to during service.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
