You're life's totally busy right now, and the last thing you need (or want) is to spend hours cleaning your home. Make it easy on yourself. Fill an ice tray with vinegar and freeze. Place the cubes down the disposal and run. The cold will coagulate grease and the acid from the vinegar will break down odors. And while you're at it, keep a spray bottle filled with straight vinegar. It's a great, all-around disinfectant and cleaner.
