depends on where the clog is. at my home I have a sink with two tubs. One of them has a garbage disposal, the garbage disposal has the dishwasher water output, and there's another tube for an overflow valve on the countertop.
Since "everythign else works", I have to assume the problem is directly in the sink, so just get a wire hanger and dig it out. If the problem were after all the pieces connect together, then you can't use a wire hanger, nor a simple plunger, because air escapes through the other outlets.
When this happened to me I wrapped plastic around the air vent and taped it solid, I sealed the sink entry to the garbage disposal, then added water to the other sink and used a plunger there.
The trick was to prevent water/air from escaping through the other openings when you use the plunger.
If that fails you can use a liquid drain cleaner..The issue being the drain cleaner can damage the disposer if it sits to long..If the drain is running slowly it would be ok ...not if it is STOPPED. Read the Label to be sure it is disposer safe.
The best way is to disconnect the trap under the sink.
Baking soda and vinegar. This really works gently and foams to loosen clogs. I try this before going any further with costly chemicals. Let it work a few minutes....it should naturally clean out and then, try plunger. I use in commode, too.
