A clean stethoscope means safe medical practice. Since stethoscopes are one of the most frequently used medical tools it is very important to clean them. If not, there is a great risk of contaminations.
These contaminations can harm both patients and healthcare providers.
This article will guide you through the process of effectively cleaning your stethoscope and what to avoid.
