for disinfecting surfaces

You should disinfect a surface whenever you suspect a surface may be contaminated — whether in an office, lab or other shared space.

When and How to Clean and Disinfect

  • ONLY ORDER commercially made, ready-to-use products made with EPA-listed disinfectants.
  • DO NOT order the ingredients to mix your own disinfectant solutions. (These supplies are only for labs.)
  • DO NOT mix disinfectants or combine their use when disinfecting surfaces; this could inadvertently create a hazardous gas release.

Follow the Centers for Disease Control and Prevention (CDC) recommendations for cleaning and disinfecting.

The CDC offers these critical safety reminders when disinfecting a surface:

  • Always read and follow the directions on the label to ensure safe and effective use.
  • Wear skin protection and consider eye protection for potential splash hazards
  • Ensure adequate ventilation
  • Use no more than the amount recommended on the label
  • Use water at room temperature for dilution (unless stated otherwise on the label)
  • Avoid mixing chemical products
  • Label diluted cleaning solutions
  • Store and use chemicals out of the reach of children and pets
