A good starting point: "Kick off your cleaning with anything that has the potential to smell bad," says Hoffman. The source of most stinky household items? The kitchen (trash, fridge, sink, etc).
Clear out the fridge
Give your refrigerator a good clean-out, removing expired products and wiping down sticky surfaces.
Clean the sink
Sprinkle your drain with baking soda followed by white vinegar; let that sit for a few minutes, then pour a kettle of boiling water down to clear out any remaining gunk.
Tackle your cupboards
One shelf at a time, from top to bottom, take everything out of your cabinets. Clean the surfaces, then put everything that's not expired back, setting aside items you no longer want for donation or the trash.
