Routine Cleaning Guidance from the CDC's Guidance for School (K-12) Responses to Influenza:

The American Academy of Pediatrics provides guidance for school cleaning and sanitizing which is appropriate for influenza. Schools should regularly clean all areas and items that are more likely to have frequent hand contact (for example, keyboards or desks) and also clean these areas immediately when visibly soiled. Use the cleaning agents that are usually used in these areas.

• Some states and localities have laws and regulations mandating specific cleaning products be used in schools. 
  
• School officials should contact their state health department or department of environmental protection for additional guidance.
• Schools should ensure that custodial staff and others (such as classroom teachers) who use cleaners or disinfectants read and understand all instruction labels and understand safe and appropriate use.
• Instructional materials and training should be provided in languages other than English as locally appropriate. 
• CDC does not believe any additional disinfection of environmental surfaces beyond the recommended routine cleaning is required.
