Your garbage disposal is not like your garbage can, so you need to discriminate between what you put in each one. Trying to stuff too much into your plumbing system is dangerous, so watch this video on decoding your garbage disposal.
A garbage can and a garbage disposal are different things. Grease, oil, and fats are fine to toss in your garbage can, but they create problems for your plumbing system if you put them in the garbage disposal. Peels from celery or potatoes can also get clogged up. Run your garbage disposal with 2 cups of ice and a cup of rock salt and vinegar if you have put grease in it.
