Stethoscope Care & Cleaning


How to keep your stethoscope in great shape


Give your stethoscope some love
Your 3M™ Littmann® Stethoscope is designed to provide years of reliable service. Cleaning it routinely ensures optimal acoustic performance, helps extend the life of the scope, and leaves it looking shiny and new.

Stethoscope Care: General Cleaning Tips

  • If your stethoscope needs to be disinfected, wipe with a 70% isopropyl alcohol solution
  • Do not immerse your stethoscope in any liquid or subject it to any sterilization process
  • Keep your stethoscope away from extreme heat, cold, solvents and oils
  • Eartips can be removed from the eartubes for thorough cleaning

Stethoscope Care: Focusing on Tubes
Most Littmann® Stethoscopes feature tubing made of polyvinyl chloride (PVC). PVC becomes hard when exposed to skin for long periods of time. If you like to wear your stethoscope around your neck, wear it over a collar to keep the tubing flexible.
