lithium grease or bearing grease
Sure. It is best if the copper is clean of grease or oil, first. Sometimes the baking soda is mixed with vinegar instead of water, but either way it is a good cleaner.
A dish soap with a detergent content higher than the water content works better on grease. A soap that has a degreaser in it will work well too.
I will answer this myself I tried every trick everybody told me I eventually rented a slide hammer puller designed for this. If you have a pilot shaft you can fill the pilot bearing blind hole with wheel bearing grease ( The old thick type works the best ). Then take the pilot shaft and drive it into the hole and it will push the old bearing out. YOU MAY HAVE TO FILL IT WITH GREASE MORE THAN ONCE. Good luck Jerry
If it's not critical that the actual surface be copper, the best solution would be to protect it with a clear coat of some kind of lacquer. This won't work if you actually need the surface to be copper (to make an electrical connection, for example), though; in that case, there's really not a lot you can do.
This question isn't specific enough to answer. What kind of bearings? What application? What do you mean by "best"? Most waterproof, most heat resistant? The answer will be different for a boat trailer, bicycle or race car.
dawn cuts grease the best
EP grease

You can get an S-Curl by using a certaint grease light grease works best.
Best way to find that out would be to get a PH strip and dip it into grease.
