Our sink is slowly having more trouble emptying as we run the cold
water out of the hot line in the morning. A plumber took the trap off
and manually chiseled out the gunk in the horizontal section going
into the wall. My knees wont support that type of work so I'm
wondering if there are any other ideas to try. Would ammonia be a
start?

Plug the overflow hole in the sink with a wet rag or your hand (I use
my hand as I can can gget a goood seal) then run some water and work it
like hell with a plunger.

You'll be amazed (and probably disgusted) with what happens.
