Ok, Since the proverbial pandora's box has been cracked open a bit,  Here's a take on the subject which I've pondered for a long time.

Any and all lubricants used in bushings does wick into the wood that surrounds the bushing rendering it impervious to any and all adhesion of the cloth to the wood.  I recall early years being taught to first use a "wetting agent" on the felting to break the surfaces of production chemicals and allowing the felt cloth surface to be able to bond felt to wood with the tiniest amount of glue. Especially important for key bushings.

Any oils and or lubricants will prevent this for happening in any future situations without providing fresh wood surface(s) for adhesion.

There certainly will render this discussion to many opinions best positive or negative about this ponder.  Ready-set-go!   chemical engineer analysts welcome into the discussion. PS rule out conjecture please. TIA

Gerry,

Yes, this is a fair point. I'm thinking that Don's suggestion (made in relative speculativity) to "soak" the de-pinned" bushings and wood in acetone might have greater merit under such circumstances. If I were doing that, I would likely follow it up with a good blast of compressed air to assist in the hopeful decontamination process. However, if the situation was a first-rate disaster requiring total bushing replacement, I think I would first drill out the bushings and then soak what's left, trying not to overdo it and send acetone all up into the knuckle and beyond. MEK might be another good cleanser, maybe...?

How about threading the flange bushing holes with a micro tap to hold the felt instead of glue?
