Hello.
I have a driver which is extremely filthy, covered in gunk, and has no voice coil, cone nor dustcap, but, is there a safe solution that I can use to clean out the part that the voice coil goes into without affecting it's performance or causing corrosion?
Meaning, will it rust or damage it in any way if I pour soap into it?
I know this sounds stupid, but, it's extremely filthy, to the point where it won't play properly because there is dirt obstructing it.
Thank you.
