Menda ESD Cleaning Brush, Curved Handle, Hard Yellow Nylon Bristles, 3" x 1-1/2" – 35689
Remove dust, dirt, and foreign object debris from electronic assemblies with this Menda static-dissipative ESD cleaning brush. Featuring a curved handle, hard yellow nylon bristles, and a conductive polypropylene handle, this brush is designed for effective cleaning in electrostatic discharge (ESD) controlled environments.
The broad 3" x 1-1/2" brush design provides generous cleaning coverage for printed circuit boards (PCBs), electronic assemblies, and suitable work surfaces. Its firm bristles help dislodge loose particles and debris that can accumulate during manufacturing, inspection, maintenance, and repair.
Unlike conventional cleaning brushes that may generate significant electrostatic charges during use, Menda's permanently dissipative nylon bristles are designed to minimize static buildup when used by properly grounded personnel. This makes the brush particularly useful for cleaning static-sensitive assemblies.
The bristles are manufactured from Type 6.12 nylon filament with permanently incorporated dissipative properties. Because the dissipative additive is part of the filament rather than a surface coating, there is no applied antistatic coating to peel or flake away during normal use.
A conductive carbon-loaded polypropylene handle provides a controlled path for charge dissipation when properly grounded. The handle is marked with the ESD protective symbol for easy identification in static-controlled work areas.
The distinctive yellow bristles are easy to see during cleaning and inspection, helping technicians identify the brush and monitor potential foreign object debris (FOD). The durable nylon filaments offer resilience, abrasion resistance, and long-lasting performance.
Suitable for dry cleaning and compatible applications using isopropyl alcohol (IPA), this reusable brush is a practical addition to electronics manufacturing, PCB cleaning, and precision maintenance workstations.

Static-Dissipative Bristles for ESD-Sensitive Assemblies
Electrostatic discharge can damage sensitive electronic components, making appropriate cleaning tools important in electronics manufacturing and repair.
Conventional brushes can generate electrostatic charges through friction as their bristles move across a surface.
Menda's dissipative nylon bristles are designed to help control charge accumulation during cleaning.
The bristles have a specified resistance from 1 × 10⁹ to less than 1 × 10¹¹ ohms, measured using a modified ANSI/ESD S4.1 test method.
This resistance range provides controlled charge dissipation rather than the rapid charge movement associated with highly conductive materials.
Menda recommends dissipative fibers when the assembly being cleaned may already hold a charge, particularly where Charged Device Model (CDM) failures are a concern.
Use the brush as part of a properly implemented ESD-control program with appropriate personnel grounding and work surface grounding.
Permanently Dissipative Type 6.12 Nylon
The hard yellow bristles are made from Type 6.12 nylon filament.
Their dissipative properties are permanently incorporated into the material rather than provided by an external coating.
This construction eliminates concerns about an applied antistatic coating peeling or flaking away during normal brushing.
Nylon 6.12 also offers resilience and abrasion resistance, making the bristles suitable for repeated cleaning applications.
The hard bristle configuration provides firm mechanical action for removing suitable deposits and debris.
For delicate components, fragile coatings, or sensitive finishes, a softer brush may be more appropriate.
Conductive Carbon-Loaded Polypropylene Handle
The curved handle is manufactured from carbon-loaded polypropylene.
Its conductive construction helps provide a path for electrostatic charge when the brush is properly grounded.
The curved profile provides comfortable handling and control during repeated cleaning tasks.
The handle is also hot-stamped with the ESD protective symbol, making it easy to distinguish from ordinary cleaning brushes.
Because the handle is conductive, the brush should never be used on energized electrical circuits.
Broad Brush Head for Efficient Cleaning
The 3" x 1-1/2" brush design provides a generous cleaning area.
This wider configuration is convenient for removing dust and loose debris from accessible PCB surfaces, larger electronic assemblies, and appropriate equipment components.
The curved handle allows technicians to guide the bristles across the work surface while maintaining controlled brushing pressure.
The firm nylon bristles can help dislodge particles that may be difficult to remove with very soft brushes.
Avoid excessive pressure on delicate solder joints, fine-pitch connections, conformal coatings, and fragile components.
High-Visibility Yellow Bristles
The distinctive yellow bristles make the brush easy to identify among other workstation tools.
Their color also supports visual inspection during cleaning and foreign object debris control.
Technicians can more easily recognize the brush and inspect the bristle area for accumulated contaminants.
Maintaining clean bristles helps reduce the possibility of transferring debris from one assembly to another.
Compatible with Isopropyl Alcohol
Menda specifies that this brush can be used with isopropyl alcohol (IPA).
This makes it useful for appropriate solvent-assisted cleaning tasks in electronics manufacturing and repair.
Before applying IPA, verify compatibility with the electronic assembly, coatings, plastics, adhesives, and other materials being cleaned.
Use only approved cleaning procedures and follow applicable chemical handling precautions.
Allow cleaned assemblies to dry completely before restoring electrical power.
Understanding Dissipative and Conductive ESD Brushes
Different ESD cleaning applications may require different electrical resistance characteristics.
Dissipative Brushes
Dissipative bristles allow electrostatic charge to move in a controlled manner. They are useful for cleaning assemblies where uncontrolled charge movement could present a risk.
Conductive Brushes
Conductive brushes have lower electrical resistance and provide a more direct path for electrostatic charge to ground when properly connected.
Menda 35689 combines dissipative nylon bristles with a conductive handle, providing a design suited to appropriate static-sensitive cleaning applications.
Always select cleaning tools according to your facility's ESD-control procedures and the requirements of the components being handled.
Care and Maintenance
Remove accumulated dust and debris from the bristles after use.
Inspect the brush regularly for damaged, bent, or excessively worn filaments.
Keep the brush clean to avoid transferring contaminants between assemblies.
When using IPA, follow appropriate cleaning and drying procedures.
Store the brush in a clean, dry location away from excessive heat and incompatible chemicals.
Replace the brush if the bristles become significantly worn or damaged.
Disconnect electrical power before cleaning electronic equipment.
