| Run some line through it, and operate it under load somehow, e.g. just use
it for a sheet block. When racing this summer, we pressed an old frozen
block into emergency duty. Although it was absolutely frozen when we started,
it was running quite smoothly by the time the race was over.

| Probably running smoothly because the corrosion products reamed the
hole out to a much oversize and now sloppy fit.
To do it right, you really should take the block apart, and polish off
the shaft.

| The block in question had ball bearings. There was no play in the sheave, so I
don't think the block was really damaged much by the exercise. This block was
riveted together, so disassembly wasn't a realistic choice.
I suspect that the operation under load had the effect of crushing the various
bad particles inside and ejecting most of the mess as dust. I'm sure this left
some scars on the ball bearing, but it converted a useless block to one that was
worth keeping as a backup or for non-critical use.

| I have had clam cleats on an old boat that experienced the same conditions. I
managed to make them reusable by soaling them in limescale remover. The stuff
used on kettles and shower heads. This process did a reasonable job.

| I wonder if a sonic cleaner like the type used to clean rings, watches,
etc. will work.
