Jeez; do a search; see the button right below 'post reply'? You will see that this topic has been exhaustively covered.
However, to answer your question, the most common thing you are likely to have already is probably a Li grease ('white grease'), or a PTFE (Teflon) / oil or PTFE / grease. A common PTFE / oil is Break Free. Any of these will perform satisfactorily. Chris Reeve recomends a PTFE / grease product.
Another thing you would likely already have is motor oil. This works surprisingly well.
You would be unlikely to have white lightning, a motorcycle chain lube, unless you ride motorcycles. Even if you did, the lube has been criticised for becoming lumpy and gummy. Tuf-Glide, the active ingredient in Tuf-Cloth, is a TFCI (Thin Film Corrosion Inhibitor). While an excellent rust preventive, many people have found it to be of insufficient lubricity for use on pivot pins. One other problem is that the very thin film tends, much like dry Teflon powder, to fail as a lubricant due to the clearance built into the parts to allow a film of lubricant of a certain thickness. The film left by a TFCI or powdered Teflon is too thin to allow the correct interaction of the parts.
