Protecting & Cleaning Neumann Microphones
Due to the current COVID-19 pandemic we assembled this note on protecting and cleaning Neumann microphones and
accessories. Especially for vocal and speech recordings, microphones are often used at close proximity to the mouth,
possibly also by multiple users.
To reduce the risk of spreading diseases through bacteria and viruses, one or more remedies, explained in detail below,
may be used:
◻
ideally, have just one user per microphone (including the accessories)
◻
after or before use, clean all surfaces, i.e. microphone housings, head baskets and accessories
◻
leave the microphone unused for some time, possibly also applying elevated temperature to the microphone
◻
utilize accessories such as windshields and thin plastic film bags to add protection
Medical Disclaimer
This note assembles technical advice on which measures may be taken, and which materials should be used or not
used, to protect and clean microphones and accessories without harming them.
For medical information on disinfection and disease spread please consult your national and regional medical
authorities and follow their advice.

Cleaning the microphone housing
For cleaning Neumann microphone housings from soiling including human exhalations, you may use ethyl alcohol
(ethanol) or isopropyl alcohol (isopropanol). Used as a disinfectant, typically a 70% solution is used. Apply with
a disposable soft cloth, a soft brush or paper tissue. Make sure that the liquid is applied only to the outside of the
microphone and does not enter the inside or the capsule.
Do not use rough materials which might scratch the surface. Do not use any solvents stronger than ethanol or
isopropanol, as these might damage the surface.
Never use sprays, as these can deposit on the membrane and thus damage the microphone capsule!
Cleaning removable microphone head baskets
With some microphones, the head basket can be easily removed for cleaning (KMS 104/105, KK 104/105, KK 204/205
and BCM 104/705). Make sure not to touch or damage the capsule!
With the head baskets containing foam windshields, remove the inner foam and clean it separately as described below
(KMS 104, KK 104, KK 204/205 and the BCM 705).
Metal head baskets can then be cleaned also on the inside with ethanol or isopropanol. You may also immerse the
head basket in clean, hot water (e.g. 70°C/160°F). Do not use the dishwasher. Let the basket dry out completely before
re-assembly.

3. Protecting microphones with foam windshields Foam windshield are mostly used to reduce wind and pop disturbances. But they also serve to protect a microphone, at least partly, from rain, water, soiling and human exhalations. Nylon pop screens are very thin and will hardly protect the microphone from exhalations. -
Page 4: Protecting Microphones With Plastic Film/Bags
5. Protecting microphones with plastic film/bags This is not a typical use for microphones, and only some recommendations can be given here. The main aim is to provide help for situations where no other solution can be applied. A foam windscreen will help, but it may not protect a microphone 100% from exhalations. So, especially for multi-user applications, additional plastic film or bags may be used as cover. -

7. Further notes Omnidirectional microphones These microphones are less affected by foam windshields and plastic bags. Contemplate the possibility of using omnidirectional microphones also for situations where otherwise you would have chosen a directive microphone. With plastic bags, a simple high frequency boost above 3 kHz may already linearize the response sufficiently.
