What do you do with powdered graphite?
Lubricate non sexual and/or metallic things which do not work well with fluid lubricants.
Most of my heavy duty (capable of supporting just around one hundred pounds) lighting stands would fail if I used liquid lubricants, but powder keeps them working as designed.
Clean them with alcohol, then lubricate them with powder = excellent. Add a few drops of oil and they will not hold even twenty pounds.
