Graphite makes having a wood-burning stove much, much easier. I use it on the turn mechanism on the iron door handle, to reduce the horrific squeak sound that inevitably happens a few times per year. Word to the wise, go easy during application! It is a powder and if you squeeze the tube too vigorously, you;ll end up in a cloud of black powder. A little goes a long way and it is always worth having around. Good sized tube, love having it delivered!

I have used this for years. Awesome stuff. Locks eventually stiffen up and are hard to open. WD works but collects dirt and grime. This stuff is dry and one application seems to be all that is required. We used these on outdoor locks in the rain, snow, wind, -50 degrees, sand storms. If build up is the issue, consider graphite.

Our front door deadbolt was sticking so bad, some afternoons, I couldn't get the key out of the door and had to get my wife to help pull on the key. She got the package in the mail, squirted it in the lock and viola, no more problems. Worked like a charm.

works a little too good ---it states to squeeze from the middle well that shoot out a whole bunch of graphite -- I was trying to get the mail box key to work but later discover the key slot was broken-- oops! Did use this sparingly on the new key & new lock key went in real smooth.

I would get so mad at my keys trying to put them in my front door... I had a little trouble getting the powder out of the tube but once I was able to spray some in...WOW! Keys enter like butter.
