The state is warning us to beware of false claims from companies who say they can clean and disinfect a home, a business, a hospital, a car, or other space with products they claim kill coronavirus. The Office of the Indiana State Chemist says cleaning services advertising such a service on air or online or in the mail can create a false sense of security. The office say it will follow up on any misleading claims they discover and take action.
