Grease drippings come from those meat juices or any juices that drip out from its pan or baking dish.
There are times where you might place food straight onto the oven racks to cook and forget to clean.
This is a cleaning job that rarely gets done, and I am guilty of it.

Place the oven racks on top of the towel.
Then, plug the drain and fill it completely to cover the racks with hot water.
Dissolve the detergent in hot water, and add it to the tub.

Sprinkle extra powder on the bottom of the towel.
Overall, this cleaning method helps the grease come off easier and to avoid excess scrubbing.
