Apply an all-purpose cleaner or disinfectant spray to surfaces such as countertops and sinks. Bathrooms should be inspected as germs can lurk around taps and levers. Protect your hands from chemicals by using gloves. After cleaning all surfaces, rinse them thoroughly with water. Dry them with a soft, clean towel. Pay special attention to the areas beneath and behind the toilet seat. These areas are where moisture can persist, encouraging bacterial growth.
