Should You Drain the Grease or Oil into Your Garbage Disposal?

The people who are against putting cooking oil, fat, and grease into your kitchen drain and through your disposal claim that the grease will solidify and harden somewhere along the line.

This is true if you use cold water to flush the disposal or you just let the greases sit there without flushing it. Plus, the grease and oil, etc., can harden on the blades and create all sorts of problems for the inner workings of your handy kitchen device.

That solid oil can attract other food particles and so on, you will have clogged disposal or drain on your hands. However, if you use hot water to flush the oil, etc., you can keep it in liquid form longer and let it solidify where it will not do any damage.

The choice is going to be up to you as it is your disposal and your drain. If you do use hot water to chase the oil, make sure to leave it on long enough to clear your smaller pipes and it reaches the larger ones in liquid form.

One way to do this is to have a jar in your kitchen where you can pour hot oil after you are finished with it. If it is clean, you can always reuse the oil and save a little money.

Or you can take that jar when it is full and toss it into your outside trash can. Just make sure the lid is sealed tight, so the odor does not attract the wrong animal element.
