I'll be replacing my electrical panel soon and I noticed that the new breakers and panel have a brown goo on them where they connect to one another. I'm guessing it is lubricant .. similar to what goes in the aluminum wires but I rather make sure than end up with fireworks.

Should I leave the brown goo in place before I plug the breakers to the new panel or should I wipe it out? Thanks.

Leave it there. It's a dielectric grease that prevents corrosion on the metal contacts. It probably does also act as a lubricant for easier installation.

    The contacts aren't steel, but yes -- it's an antioxidant/dielectric material. – ThreePhaseEel Sep 14 '18 at 1:03

It looks like no-ox-id. This is a special anti oxide lubricating grease.
