Best penetrating lubricant

I love WD-40. Just bought a fresh two pack from Amazon.

If you have ever removed an adhesive label, and adhesive was left behind...WD-40. I use it to clean off chain lube splatter on my motorcycle and bicycles. On my bikes, after water washing, I hit the various components with WD, to remove moisture and lightly lubricate. I use it on my golf club pull cart, to lube the pivots, and clean grime off the frame tubing. It brightens up dull old paint on things like this also. I handed my kid a can and rag, and he went to town on all the plastic and painted parts of his MT07, and the bike looked like new afterwards.

No fallacy that it's a great lubrication, but it's better than nothing, and has quieted down many things like door hinges, electrical switches, etc. Bash if you want, I like the stuff.
 
WD40 is great for wiping down tools after I'm done working on a vehicle. I've get to find another use for it where there's not a better product easily found.

Unfortunately, I think basic mineral spirits might even have the advantage over WD40 at the trivial task of tool wipe down oil.
Same here. We somehow got to spraying down our hand tools with WD40 and wiping off with red rags at our shop work tables at the end of jobs before we stored them. I guess since we used them nearly every day, I never found the WD40 to do anything but keep them clean and rust free. I am positive there has to be better stuff out there now a days but that's just what we had at the time.
 
There's a lot of misconceptions about what WD-40 is good for. The WD stands for "water displacement", which is what it's best at (took them 40 tries to get it right). As far as lubricating properties go it's extremely lightweight and has very little staying power, it's actually more of a solvent than a lubricant which gives it good cleaning properties and is safe for most surfaces except some plastics.
It has some penetrating qualities, but nowhere close to the dedicated stuff.
Actually, WD-40 is now a brand name for a whole line of products, including a penetrant. One would have to refer to the original WD-40 in any discussion about the good old WD-40 that grandpa used. ;)
 
I use it often, I have it in my garage and on my basement work bench. I found it to be very useful and will be buying more. Give it another shot, applying it over time might be just the ticket for you. Good luck!
Unfortunately after a few days the loud noise returned. I hit the hinge a few times, didn’t seem to help in terms of more insertion since the sound came back.

I wish I understood these hinges more. Not sure how there’s a door check and stopping points in such a small setup. Im tempted to pull the bolts and slide them apart and get something more in there. But if the thing comes apart in a weird way with the door supported on one hinge on a block of wood, it would be a soup sandwich.

Be careful. Automobile doors are extremely heavier than lots of folks think they are.
 
The problem with most penetrating oils is there not actually a lubricant.

The key to sneaking around seals is a lubricant with very low surface tension. In the industrial world we use low surface tension fluids for lots of things, and our problem is keeping it out of places it shouldn't be, not getting it in. The getting in part is known as "creep". Based on this if I were in your boat I would try something silicon based first. Low viscosity silicon has very low surface tension.

I have actually found the liquid silicon designed for treadmill belts works really good on lots of stuff.
👍on the treadmill silicon oil. That stuff is really slick.

I know. I’ve replaced door hinges on one of my Dodge Ram trucks. It was successful.

Isn't the "best penetrating lubricant" sitting on the shelf next to the "best" oil, right down the aisle from the "best" filters ????

I kid in jest.

Sort of ...
Sure. But some work better for some applications than others. Some may have more creeping or solvent action.

I want penetrant only so fr as it actually wicks a long lasting lubricant in there. Not to bust a bolt, break rust, etc.

Obviously most don’t work for this.

Something besides a petroleum/solvent based lube may be worthwhile.

Sorry to hear that. Is there any way of injecting grease in there?

True. But just like Spam, even though they make a number of versions, everyone defaults to the OG when they hear the name.
