I remember reading somewhere that foam (used in windscreens and sometimes in the original packaging - i.e. D112) is no good for microphones... Apparently after about 3 months or so the foam starts to break down and the 'foam dust' -or whatever you call it- sticks to the capsule/diaphragm causing a buildup, and eventually, sound degradation.
1. Is this true?
2. Do you use foam windscreens?
3. How/Where do you store your mics when not in use?
I guess there could also be a problem with regular old dust too... so I have heard that in situations like drum tracking (where the mics could be up around the kit for several days) to place zip-lock plastic bags over the mics for protection...
4. Do you/how do you protect your mics from dust in long tracking situations such as what I have described above?
