When focusing on public restroom sanitation, a facility manager needs to take into account several key factors. The No. 1 priority should be the safety of the people using the restrooms every day. Education institutions should make sure they are using chemicals that are not only effective, but also environmentally friendly; they should provide ongoing training to staff and use effective cleaning protocols. Public perception is important in how a school is viewed. If restrooms are dirty, visitors will likely think that the rest of the facility also is unhygienic. Remember, first impressions are everything, and these first impressions usually result from appearance and cleanliness.
