MODERATORS
Top tip: don't use WD40 as a lubricator.
It's more of a solvent.
It will lubricate in the short term, but the film it leaves is too thin to protect in the long term.
It's great for removing old grease and old oil, breaking rust, stuck nuts etc.
But it shouldn't be the last thing you use in maintenance.
Once you have something moving again and all cleaned up, make sure you use some proper oil to protect it long term (3-in-1 oil is good, there are more application-specific lubricants as well)
Thank you.. this explains why my squeaky items keep squeaking every few months
