How to Clean Your 3M™ Littmann® Stethoscope
The Essential Guide to Stethoscope Hygiene for Clinicians
One of the most common — and crucial — questions we receive is:
“How do I properly clean my Littmann stethoscope?”
Maintaining a clean stethoscope isn’t just about appearance. In clinical settings, it’s a vital part of infection control and patient safety. Since your stethoscope makes direct contact with patients, regular cleaning helps prevent the spread of harmful bacteria and viruses.
Here’s how to clean your Littmann stethoscope safely and effectively:
Step-by-Step: How to Disinfect Your Littmann Stethoscope
Use a 70% isopropyl alcohol solution
- Apply to a soft cloth or use pre-packaged alcohol wipes.
- Gently wipe down all parts that come into contact with patients after each use.
Avoid harsh or damaging products
- Do NOT use hand sanitizers, essential oils, or multi-surface disinfectant wipes.
- These may contain chemicals that can degrade your stethoscope’s tubing and chestpiece.
Don’t immerse or soak your stethoscope
- Never submerge your Littmann stethoscope in any liquid or subject it to sterilization methods (like autoclaving).
Why Regular Cleaning Matters
Your stethoscope is used in dozens — sometimes hundreds — of patient interactions each week. Over time, it can accumulate bacteria, skin oils, and other contaminants.
By cleaning your stethoscope between every patient assessment, you:
- Help prevent cross-contamination
- Maintain hygienic best practices
- Prolong the life and acoustic performance of your device
Additional Cleaning Tips for Your Littmann Stethoscope
Chestpiece & Tunable Diaphragms
- Detach the diaphragm from the chestpiece.
- Clean with alcohol or mild soapy water.
- Dry completely before reassembly.
Eartips
- Remove from the headset for a deeper clean.
- After cleaning, snap eartips back onto the ribbed ends to ensure a secure fit.
Safe Cleaning Solutions
You can safely use the following on all Littmann models:
- 70% isopropyl alcohol

Avoid:
- Hand sanitizers or essential oil-based cleaners

What Makes Littmann Next-Generation Tubing Special?
All modern Littmann stethoscopes are built with next-generation tubing, engineered for:
- Superior resistance to skin oils and alcohol
