Only use a hint of dish soap and warm water to clean your refrigerator. Store a box of opened baking soda in the back corner and label it with the date using a black sharpie. The box should be replaced every 30-50 days.
Hot water and dish soap will perform wonders on your kitchen cabinets. Always use a clean sponge or cloth, and make sure to not get your cabinets completely saturated.
Each time you take the trash out, before replacing your trashcan with a clean liner, spray it down with some Lysol. It will not only leave a fresh, clean scent, but it will also disinfect.
Clean your dish drainer once every two months by either washing it in the dishwasher (only if dishwasher safe), or letting it soak in the sink with hot water and a few drops of bleach (be sure to rinse well).
