Keep away from the wet electrical area and stop using the sink and connected appliances. Isolate the supply only by a safe, dry, accessible means; do not handle a wet plug or reach through water.
What the observation tells you
Drying the cabinet surface does not establish that the electrical parts are safe. Water may have entered an enclosure or remained behind it. Do not reconnect power simply because the visible puddle has been wiped away.
A useful next step
Obtain appropriate urgent assistance and explain which electrical items became wet. Both the leak source and the affected electrical arrangement need assessment before the disposer is returned to use.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
