I shall now let you all know the secret lube used by us steam-age boring old wrinkled fahrts, creaking about on our zimmer frames. This is not, I assure you, a joke, I have used the stuff for decades on old machines to ease parts together or apart. You can buy in at any 'Walmart' and it's cheap:
Bananas!!!!!!
Banana pulp, the finest and slippery-est lube known to man.
Biodegradable,
Non-toxic,
Water-soluble,
Will not age to glue.
Won't cause rust, won't affect plastic, copper, rubber, steel or aluminum.
Slippery as a Wall Street lawyer.
Can be also fed safely to Elephants.
Low calories, so any excess can be fed to the crew as a bonus.
And - it smells nice!
