try using the ice cubes without water at first. the disposer makes a lot of
noise, but run it for a few minutes without water, just cubes. then run
water.

it cleans disposer pretty good. the drain might freeze up, but will thaw
after a few minutes.

TRY a sink full of ice cubes and some cold water, that should help losen
anything down there.
