What about 'Slippy Stuff'... Teflon powder suspended in white spirit... created by Neil Brook as a dry lubricant for Hurdy Gurdy keyslides.
It's a similar problem, so I'd proffer this as a similar solution... and less drastic than pulling the keyboard apart.

BTW bulk manufacture of concertina reeds - stumbled on these people who use 5,000 per annum!! Perhaps useful technical details
