Does this capsule need cleaning?

[Joe B]

Hi. I have just purchased a used Rode NT1 and inspected the capsule. It has some dust on in (see photo). Is this ok for a used mic or is it an excessive amount of dust which needs to be cleaned? Thank you. Joe

There is a little bit of dust, but as it is now it is not problematic.
Edge terminated microphone capsules are not as sensitive to pollution as center terminated capsules.

Thank you so much!
