powdered graphite or the impregnated sprays?
I have used both. Being out of spray (for which the carrier evaporates dry, leaving the graphite), I happened to use powdered graphite today. I never run out of that, because I need it from time to time for older locks we have here and there. I could also have used some of the spray bicycle cable lube I have, which also evaporates dry leaving a lubricating film, but that stuff is more expensive.
Any of these alternatives make a decade-old brass bolt snap operate as though it were new. They don't hurt the operation of SS ones a bit, either!
