Hi Layla,I also learned a great trick, from my Dad. When I've used this trick, it's nearly always worked like a champ:
When your drain is clogged, and you have a garbage disposal, try this: take the back end of a broom, a mop, etc, insert it between one of the disposal blades, and with pressure and vigor, move it back and forth, to budge the blades to move.
It takes a few moments and a little effort, but soon, your drain won't be clogged and your disposal with hum like a song
Be sure to run water with your disposal, for a few moments, to make sure it's working fine.
Big love,
