Cleaning and Maintenance
Follow recommended care and cleaning instructions in order 
to maintain best noise reduction and function.
Cleaning
• Carry out a visual battery condition check. Replace if 
battery leakage or defects are detected. 
• Use a cloth wetted with soap and warm water to clean the 
outer shells, headband and ear cushions. 
NOTE: Do NOT immerse the hearing protector in water. 
If the hearing protector gets wet from rain or sweat, turn 
the earmus outwards, remove the ear cushions and foam 
liners, and allow to dry before reassembly. The ear cushions 
and foam liners may deteriorate with use and should be 
examined at regular intervals for cracking or other damage. 
When used regularly, 3M recommends replacing the foam 
liners and ear cushions at least twice a year to maintain 
consistent attenuation, hygiene, and comfort. In hot and 
humid environments more frequent changes may be required 
to maintain acceptable hygiene. If an ear cushion is damaged, 
it should be replaced.
