premise: To clean a microwave oven.
hypothesis: Here is what is needed for this microwave cleaning hack:        Vinegar        Lemon juice        A small cup        Mix about 5 parts vinegar with one part lemon juice.        I fill a small cup half full with vinegar then added two spoonfuls of lemon juice.        Give the mixture a slight stir.        Place your cup into the microwave and cook for 2 minutes.        After the microwave is done leave the mixture inside for about 5 more minutes before opening the door.        After leaving for 5 minutes proceed to wipe down the microwave with a clean damp cloth.        The grime just comes right off!
