Cleaning and Care


Your Littmann stethoscope is designed to provide years of reliable service. Routinely cleaning your stethoscope will ensure optimal acoustic performance.

General cleaning instructions:

  • Do not immerse your stethoscope in any liquid or subject it to any sterilisation process. If disinfection is required, the stethoscope may be wiped with a 70% isopropyl alcohol solution
  • Keep your stethoscope away from extreme heat, cold, solvents and oils
  • Eartips may be removed from the eartubes for thorough cleaning

Tubing Care

The majority of tubing used on Littmann stethoscopes is made of PVC (polyvinylchloride) which becomes hard when exposed for long periods of time to the lipids found in human skin. Wearing the stethoscope around the neck may cause stiffening of the tubing over time. If worn around the neck, we recommend wearing the stethoscope over a collar, away from contact with your skin.
