I've only used machine oil compounds for lubrication previously, lithium grease is new to me. What do I watch out for?
I mean when using machine oil and similar stuff it should not be applied to plastic because many plastics get dissolved this way. Also machine oil will stain porous materials and those stains are nearly impossible to remove. Other than that machine oil is more or less fool proof - can be applied to any metal, doesn't damage it.
What are similar guidelines for lithium grease?
