Default Re: Grease

"Copper grease" should be avoided on rotational bearings - it's abrasive.

Are we talking about phosphor-bronze 'Oilite' sintered-type bearings? If so then these are best *oiled* rather than greased.

The bearing is porous, a bit like a sponge. If you can push the bronze bush out of its housing, soak it in petrol/acetone/brake-cleaner for a few days to remove the age-congealed lubricant, then blast it dry with compressed air and soak it in *thin* oil [3-in-1 or 'sewing-machine-oil' are good options] for a few days to to relubricate it.
