Start by looking around your building for dust and debris that may have accumulated behind furniture or in corners. The dirt can be cleaned with a vacuum cleaner or a broom. Use an all-purpose cleaner for surfaces like countertops and sinks that are susceptible. Bathrooms are important! Be sure to clean and disinfect all fixtures, such as toilets and taps. Protect your skin from potential irritants by wearing protective gloves when handling chemicals. After cleaning all surfaces, rinse them thoroughly with warm water. Dry them using a soft cloth.
