Introduction: Why Proper Endoscope Cleaning Starts With the Right Technique
Flexible endoscopes are among the most valuable diagnostic and therapeutic tools used in hospitals, ambulatory surgery centers, GI laboratories, urology clinics, and specialty healthcare facilities. However, their complex design creates an important challenge: proper cleaning after every procedure.
Unlike simple medical instruments, flexible endoscopes contain narrow internal channels where blood, mucus, tissue particles, and organic debris can remain after use. If these areas are not cleaned correctly, the entire endoscope reprocessing workflow can be affected.
Many healthcare professionals and sterile processing teams face common challenges, including:
- Choosing the correct endoscope cleaning brush size
- Ensuring complete channel cleaning
- Maintaining consistent reprocessing procedures
- Reducing workflow errors
- Selecting reliable endoscope cleaning accessories
Proper manual cleaning using the correct endoscope cleaning brush is a critical step before high-level disinfection or sterilization.
Why Endoscope Cleaning With a Brush Is Important
Endoscope reprocessing is a multi-step process designed to prepare reusable medical devices for safe patient care.
The first and most important step is manual cleaning.
During procedures, endoscopes can collect:
- Blood
- Tissue residue
- Mucus
- Organic materials
- Microbial contamination
Because flexible endoscope channels are narrow and difficult to access, simple rinsing may not remove all contamination.
An endoscope cleaning brush works by physically contacting the inside surface of the channel and helping remove debris before further disinfection.
A simple way to understand this process is to compare it to cleaning a small tube. Water can remove loose particles, but a brush is needed to scrub away material attached to the inside surface.
According to the Centers for Disease Control and Prevention (CDC), cleaning must occur before disinfection because organic material can interfere with the effectiveness of disinfectants.
Step-by-Step Guide: How to Clean an Endoscope Using a Brush
Step 1: Begin Point-of-Use Pre-Cleaning Immediately After the Procedure
The cleaning process should begin immediately after the procedure is completed.
Healthcare professionals should:
- Remove visible contamination
- Wipe the exterior surface
- Flush channels according to manufacturer instructions
- Prevent debris from drying inside the endoscope
Why immediate cleaning matters
When biological material dries inside an endoscope channel, it becomes more difficult to remove.
A consistent point-of-use cleaning process helps sterile processing teams achieve better results during complete reprocessing.
Step 2: Perform an Endoscope Leak Test
Before immersing the endoscope into cleaning solutions, perform leak testing according to manufacturer instructions.
Leak testing helps:
- Identify damaged equipment
- Protect internal components
- Prevent additional device damage
If an endoscope shows signs of damage, it should be removed from service and evaluated.
Step 3: Prepare the Correct Cleaning Solution
Use a compatible enzymatic detergent recommended for the specific endoscope.
Important preparation steps:
✔ Follow detergent instructions
✔ Use the correct concentration
✔ Prepare fresh cleaning solution
✔ Follow manufacturer Instructions for Use (IFU)
Incorrect cleaning solution preparation may reduce cleaning performance.
Step 4: Select the Correct Endoscope Cleaning Brush
Choosing the correct brush is one of the most important parts of manual cleaning.
The ideal endoscope channel cleaning brush should:
- Match the internal channel diameter
- Reach the required channel length
- Provide effective bristle contact
- Move smoothly through the channel
Using the wrong brush size can create problems.
If the brush is too small:
- It may not contact channel walls effectively
- Residual debris may remain
If the brush is too large:
- It may create unnecessary friction
- It may damage sensitive components
Healthcare facilities should always select brushes compatible with their endoscope models and manufacturer recommendations.
Step 5: Brush All Accessible Endoscope Channels
Proper brushing technique is essential for effective manual cleaning.
Recommended process:
- Insert the cleaning brush into the correct channel.
- Advance the brush completely through the channel.
- Remove collected debris from the brush.
- Repeat according to cleaning instructions.
- Clean each accessible channel individually.
Do not skip channels.
Different endoscope channels may collect contamination differently, and each accessible pathway requires proper attention.
Step 6: Flush and Rinse Endoscope Channels
After brushing:
- Flush channels thoroughly
- Remove loosened debris
- Remove cleaning solution residue
- Prepare the device for disinfection
Brushing and flushing work together.
The brush removes attached contamination, while flushing helps transport loosened material away from the channel.
Step 7: Inspect the Endoscope Before Disinfection
Before moving to high-level disinfection, perform visual inspection.
Check:
- Distal tip
- External surface
- Valves
- Connectors
- Channel cleanliness
If visible contamination remains, repeat manual cleaning.
Quality inspection helps maintain consistency across the reprocessing workflow.
Step 8: Complete High-Level Disinfection and Proper Drying
After successful manual cleaning:
- Perform high-level disinfection according to approved procedures
- Rinse properly
- Dry internal channels completely
- Store the endoscope correctly
Proper drying is an important part of maintaining a safe storage environment.
CDC guidance emphasizes appropriate cleaning, disinfection, drying, and storage practices for reusable medical devices.

Common Endoscope Cleaning Mistakes Healthcare Facilities Should Avoid
1. Using the Wrong Brush Size
A brush that does not match the channel size may reduce cleaning effectiveness.
Solution: Select brushes based on endoscope specifications.
2. Skipping Manual Brushing
Automated systems support reprocessing but do not replace proper manual cleaning steps.
Solution: Maintain a standardized brushing process.
3. Delaying Cleaning After Procedures
Allowing debris to dry can make cleaning more difficult.
Solution: Begin point-of-use cleaning immediately.
4. Inconsistent Staff Training
Different cleaning techniques can create workflow variation.
Solution: Provide regular training and competency evaluations.
