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.

I was trying to replace a few damaged boards in my floating wood flooring. I found removing the damaged pieces very easy to remove after watching a few how to videos on you tube. Sliding the replacement planks it was not as easy. I would get the plank in about halfway and it just quit sliding forward. I used a protective block to tap the end of the plank into place but still couldn't get them all the way in. I decided to give some L300 Powdered Graphite Lubricant a try. It worked great and I got the flooring back down. It's a little messy and a little goes a very long way. This should be in every toolbox. I'm so glad I bought this!

I used this on my automobile locks which makes them easier to operate. The easiest way to apply it to the key itself and then insert into the lock and give it a few turns to spread it out. A small extendable straw would make it easier should you want to apply the graphite to the locks themselves. It will make the locks work better and will not attract contaminants like a spray on or silicone may before it dries. Always use Graphite for locks.

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.

I could not get the key in or out of the main door lock without spending a few minutes on it and lots of force. It was a nightmare. A tiny bit of this graphite and the lock is like new. In an instant worked without any problems and so smooth! A life saver product :) No need to call the locksmith :)

I can't stress enough that this stuff gets EVERYWHERE. So apply it to whatever on top of a rowel or something u don't care about. Then work the applied item back and forth, THOROUGHLY or little flakes of graphite will get on the floor and smear all over. Also if u apply this stuff to a rod that's sitting horizontal, use something else, cuz this stuff just falls off. It's best used on vertical things like hinges.

This stuff is essential! Oil lubricants capture dirt and dust. WD-40 can remove lubricants. Both of those things can make an existing problem worse. This is dry, superfine, goes on like baby powder and doesn't bind or gunk up. A few "puffs" into an old lock tumbler and it works like new... maybe even better. Great for padlocks, bike locks, car doors.. any sticky key or locking mechanism, and a lot more.

I use it to lubricate two pieces of wood that are constantly in contact and moving. Product has worked awesome at allowing wood to glide along each other like a knife through butter. If you are also using it for wood applications, please note that since this is powdered graphite, it will make a similar mark to a pencil drawing on wood. For my purposes it doesn't matter but for others it may. Sounds like everyone else has had great results using it on metal too (e.g. door locks, hinges, etc.) One piece of advice is to be careful applying it. You don't need them much to work effectively. Otherwise you may end up with it all over your hands. Let's just say I learned that the hard way on the first application.

Lowered rating because description says non-toxic (which I assumed anyway), but packet says "chemical known to State of California to cause cancer and birth defects or other reproductive harm".
