Can you put heat to it and it melt some or liquify ?
Yeah it's just old cam lube. Schneider still uses it, some others too. Many have gone to the red stuff that is very viscous and the other like light weight grease...then theres Lucas which has a nice green assembly lube like comps I like as well....then the old cosmoline type that Chrysler used/s... lubriplate napa...lol...sta-lube moly grease ...I think I've used it all...theres a few more too I'm forgetting..
You could just add more to it...or like you said spray it off and start over.
