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

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.

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.

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.

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.

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.

I had been using WD-40 to make turn key locks easier to open. Tried this instead but I think the WD-40 works better.

the deadbolt lock on my front door had become so "sticky" i stopped using it (luckily there was a second lock on the doorknob).since i couldn't trust my nearly dead deadbolt to work reliably, i decided to replace it. but before i called the locksmith i tried this lubricant because a friend told me that powdered graphite would do the job – no matter how corroded the lock was.how true!i applied a very generous amount of this lubricant into the keyhole and onto the deadbolt itself, worked the lock back and forth then repeated the process a couple of times. within a few minutes the key turned effortlessly, the lock engaged and disengaged without sticking and i saved myself the cost of a locksmith's service call along with the price of a new deadbolt.this stuff works wonders!!

The key for my main door was getting harder and harder to insert. Google said graphite powder or wd40. I opted for this. It worked great but I had some issues, likely user error. My first squirt I don't think much came out. Second, too much came out. The second one I could slide the key in sooooo smoothly BUT I must have clogged the lock with the powder. The key would not turn. Luckily, the issue went away after letting it sit a full day. I'm guessing the powder just slowly fell out. I recommend doing a few squirts over the trash can if this is your first time attempting this. And now I have a tube just sitting minus 2 squirts.
