No need to melt it. Fact is, rubbing is rather vigorously will soften it up. I used to work in an uncooled factory and the paraffin blocks we used became pliable at about 90 degrees Fahrenheit.
Yet another problem with graphite is that it’s impossible to put the stuff only where you want it. Save it for the door locks.
I’ve always just used an emergency candle. Yes, they’re sold under that description, usually in camping goods. No scent, no dye, and larger than decorative candles.
Also works well for screw lubricant.
Utility candles work great for lightly waxing some lines on a boat to. We use a lacing line to hold the main sail to the main mast and the wax really helps with raising and lowering the main sail. We rewax about once a month during the season.
This works.
Other people have said it, but you don’t melt it, you just rub the wax on any parts that rub against each other. And I misspoke when I said wax would seal the wood, it’s going to protect the waxed areas from losing or gaining humidity to a degree but it won’t be perfect.
Augh, I’ve said the word rub too much! Rub rub rub rub.
Rub.
