Panef Corp. L-300 Powdered Graphite Lubricant - Net Wt .21 oz

Bought this to take the squeaks out of my metal fireplace insert. I has two metal doors where the inner hinge (part that rubs) was slightly rusted. An oil or silicon lube would have worked but then evaporated or become sticky after being heated by the fire. This graphite worked great. Better than expected even: no more squeaks!There is one tradeoff: the little tube this comes in. Since this is one of the less-expensive graphite products like this, the little tube it comes in is very basic. It works by having a small amount of air in the plastic tube. By squeezing, the air comes out and puffs along an amount of the powdered graphite. It's slightly inaccurate. I put down a piece of paper to catch the excess powder that missed the target and that worked ok to contain it. I wish it had a longer, flexible tube to direct the powder where I want it more accurately. Oh well, I just kept squeezing until I thought I had enough.As I said before, this powdered graphite worked great for me. There is still a bunch left in the bottle for something else if I need. I squirted a bunch into some of my door locks that were too stiff and now they have a much smoother action. WD40 couldn't do that when I tried it last year.Have a rough, sticky, or squeaky metal joint, and you don't want to pay too much? Get this, it'll probably do the job.

Good stuff but wear lung and eye protection, and put paper down under it.It's not toxic, but will irritate your lungs, and is so finely ground (part of the design) that it can easily get in your lungs. It will also spread in an 12 foot + diameter circle if you accidentally drop a tiny bit from 7 feet (confirmed with a flashlight while cleaning up with a shop vac after lubing the sticking metal pull cord on a ceiling lamp. In a room with zero wind.)So, it does the trick, is better than oil for many household applications (especially locks), but you need to keep kids and pets out of the room, cover your mouth and eyes with something, even if it's just glasses and a bandana or t-shirt tied over your mouth. And put the bandana or t-shirt in the laundry after use.Vacuum the whole room after. If you need to see where this ends up, turn off the room lights and use a flashlight in the dark room. This will sparkle like microscopic diamonds (which it resembles chemically) even places you can't see it in normal light.

Trying to apply this into an exterior keyhole was tricky. You're supposed to hold the tube somewhere in the middle, put the tip into the keyhole, and squeeze the tube quickly to force out some of the graphite into the lock. This is kinda messy. Most of the graphite sprayed all over the door because it's just not well directed through the tip of the tube. Glad I was outside using it.After a couple puffs of graphite in the general direction of the keyhole, I was able to get the key in and turning again, so it does work! I was surprised and quite pleased with how well it worked. Just could do with a bit of tweaking on the application method.

Living in a cold climate means that locks can freeze up if they get wet.Dry lubricants like these are great for permitting locks to operate in harsh climates so treat your locks before you get locked out of your vehicles, which happened to me.One thing! Don't go overboard on squirting it inside your locks because if you get too much in there, the key won't fit.Shake the tube gently while holding it horizontally to get the graphite to level out and squeeze it a little.Test it with the key and check it to see that has graphite on it and leave it at that.A little is better than too much.I had to take a paperclip and scrape the extra graphite out of my ignition switch to get my key in there to start the vehicle.Don't do that, hah.

It’s graphite, nothing more, but this brand, in the same tube, I used 40 years ago on my skateboard. That says something about a product, it shows that it works. 1 squeeze in your lock is all it takes, then I like to rake my key in & out of the lock to spread it around.Be careful not to fill your lock up, it’s possible to put too much in, so start with 1 squeeze & if you need more after raking the lock, put another in, just take it slow.Graphite can be used for more than just locks. Put it on a zipper that’s hard to zip up & down, on knifes & multitools if the blades & other parts are hard to get in & out.It’s a lubricant, just think of it like that if your wondering what it’ll work on.

Tremendous. Better than possibly expected. My lock had been getting rather sticky, and few times in the winter it would take 5 minutes of repeat attempts to get the door open. Very frustrating.One "puff" and your lock is entirely reinvented, smooth, slick and keys have no issue at all. So surprisingly quick and effective that I started laughing at how silly I was not to have known about it before.Two things of note. You must "cut off" of the top of the nozzle with a scissors or blade before you can use it. Also, I had read some reviews about placing the lubricant onto the key first, and then putting the key into the lock. Don't do that, you are liable to get the black powder all over the place and your hands, and it will not be as effective. Simply place the nozzle into the keyhole, apply light pressure, and remove. Voila.

The graphite worked well. I used it on door hinges. Took a little bit more than I expected, but still worked out. After you add it to the hinges you need to open and close the door about 20 times to really work it in there. However, no more creaks from the doors. I also had a door handle that was squeaking. I took it apart and added a few puffs and it stopped making noise.Keep something handy to clean it up with though. It can be really messy and hard to clean if you aren't paying attention to where it goes.

It works for my guitar nut.
