Begin by inspecting the entire building for dirt or debris that may have accumulated behind furniture or in corners. Once you have identified the dirt, you can use a vacuum or brush to get rid of it before moving onto deeper cleaning. To clean sinks and countertops, you can use an all-purpose cleaner. You should also take care of bathrooms. For maximum hygiene, ensure that taps and toilets are clean and well-sanitized. Wear gloves to protect your skin from chemical irritants. After cleaning all surfaces thoroughly, rinse them with clean water and dry with a soft towel.
