Proper cleaning and handling of NeXus systems, sensors, electrodes, and caps is essential for:
Reliable signal quality and measurements
Long-term durability of hardware
User safety and hygiene
Preserving product warranty
We increasingly observe damage, contamination, and premature wear caused by incorrect cleaning methods, misuse of consumables, and poor hygiene practices. This document defines mandatory cleaning and handling guidelines for all Mind Media NeXus systems.
Failure to follow these instructions will result in warranty being void.
Scope
These instructions apply to:
All Mind Media NeXus systems
EEG, EMG, ECG, EOG and other NeXus sensors
Electrodes (Ag/AgCl, passive, active)
EEG caps (fabric, elastic, and integrated electrode caps)
Sensor cables and connectors
General Hygiene & Handling Principles (Mandatory)
Clean after every use
Sensors, electrodes, and caps must be cleaned immediately after each session.Never immerse electronics
Sensors, amplifiers, cables, or connectors must never be submerged in liquid.Use only approved cleaning agents
Harsh chemicals permanently damage plastics, coatings, electrodes, and seals.Handle consumables correctly
Conductive paste and gel must be applied hygienically and sparingly.Prevent cross-contamination
Equipment used on multiple clients must be cleaned between users without exception.
Approved Cleaning Materials
Allowed
Mild liquid soap (pH-neutral)
Warm water (not hot)
Soft cloth or microfiber cloth
Soft brush (e.g. toothbrush) for caps only
Disposable wooden or plastic spatula/spoon for paste application
NOT Allowed (Strictly Prohibited)
Alcohol or alcohol-based wipes or solutions (unless explicitly stated in the official Mind Media IFU for the specific product)
Acetone
Bleach or chlorine-based cleaners
Hydrogen peroxide
Ammonia-based cleaners
Abrasive sponges or brushes
Ultrasonic cleaners
Dishwashers or washing machines
Sprays directly applied to electronics
Use of prohibited materials voids warranty immediately.
Cleaning Instructions by Component
1. NeXus System (Main Unit)
Never immerse or spray liquid directly onto the system.
Procedure:
Power off and disconnect the system
Wipe the exterior with a lightly damp (not wet) cloth
If needed, use a cloth with mild soap solution
Dry completely with a clean cloth
Important:
Do not allow moisture near ports or connectors
Do not open the enclosure
2. Sensors & Cables
Sensors contain sensitive electronics and seals.
Procedure:
Remove visible paste or gel immediately after use
Wipe sensor surface with a damp cloth
Use a small amount of mild soap if needed
Wipe again with clean water
Dry thoroughly before storage
Disinfection notice:
Mind Media does not publicly authorize the use of chemical disinfectants (including alcohol-based products) for NeXus systems, sensors, electrodes, cables, or caps unless explicitly stated in the official Instructions for Use (IFU) for the specific product.
When enhanced hygiene is required (e.g. multi-user or clinical environments), cleaning must be performed using water and mild soap only, followed by thorough drying. For additional guidance, contact Mind Media Support.
3. Electrodes (Ag/AgCl and Others)
Electrodes are wear components and must be treated carefully.
Correct use:
Apply conductive paste only onto the electrode surface
Use a clean spoon or spatula
Never dip electrodes or sensors into a paste container
Strictly forbidden:
Inserting electrodes or sensors directly into paste jars
Reusing contaminated paste
Cleaning procedure:
Remove paste immediately after use
Rinse electrode with warm water
Use mild soap if residue remains
Rinse thoroughly
Dry completely
Overuse warning:Electrodes have a limited lifespan. Excessive reuse, aggressive cleaning, or poor hygiene accelerates degradation and affects signal quality.
4. EEG Caps
Procedure after each use:
Rinse cap with warm water
Gently clean with mild soap
Use a soft brush only if needed
Rinse thoroughly
Air-dry completely (do not use heat)
Important:
Do not wring or stretch caps
Do not tumble dry
Do not expose to direct sunlight or heaters
Conductive Paste & Gel – Proper Use (Critical)
Correct Application
Always use a clean, disposable spoon or spatula
Apply paste only to the electrode or cap opening
Close paste container immediately after use
Incorrect Use (Observed & Prohibited)
Dipping electrodes or sensors into paste containers
Using contaminated paste
Leaving paste to dry on electrodes or sensors
Improper paste handling leads to:
Contamination of consumables
Corrosion of electrodes
Permanent sensor damage
Storage Guidelines
Ensure all components are clean and dry before storage
Store in a clean, dry environment
Avoid high humidity and extreme temperatures
Prevent cable bending or strain
Warranty & Liability Statement (Important)
Mind Media warranties cover manufacturing and material defects only.
The following will void warranty immediately:
Failure to clean equipment after use
Use of prohibited cleaning agents
Immersion of sensors, cables, or systems in liquid
Improper handling of conductive paste or gels
Contamination or corrosion due to poor hygiene
Excessive or improper reuse of electrodes
Mind Media reserves the right to refuse repair or replacement if damage is caused by misuse, improper cleaning, or negligence.
Training & Compliance
These instructions are intended for:
End users
Clinicians and practitioners
Training institutions
