Celestion SL-6 corrosion on speakers - paint or oil to protect
Hello,
My Celestion SL-6, were working but stopped, but it may have been the amp. Either way, i thought id check inside the boxes, and was quite shocked at the white fluffy stuff on the drivers. I thought it was the heavy dampening material as its quite flakey. There is no air conditioning at home so its quite humid here in summer, being a sub tropical climate in Australia.
I wiped and scraped some of it off, my hand was grey lol afterwards. There is some tiny rust spots. Also the old speaker gaskets have worn, so maybe air made it in that way or via the terminals.
Any ideas, my brother and another Aussie recommended a light rub with MX3 anti-corrosion, anti-moisture lube.
I can check the box internal seals also to make it more airtight or desiccant (little), PVA glue to seal the box joints or silicone?
