I don't understand the 2 negative reviews. I use Blaster products all the time and they work great. Yes, it is messy and anyone who's ever messed with 325+ mesh graphite already knows just how messy we're talking about. The nature of graphite means wiping it off with a wet rag will probably rip some paint away.Then there's over-use. It comes out fast and you need very little. We're not spraying WD-40 here we're spraying what is a solid... You can seize up your locks by spraying a bunch in there and having it essentially turn into a solid rock.At any rate, I use this in many appropriate locations and it works great. It's nice to have powdered graphite in a nice clean can that is easily stowable.
Got this because the store was out of graphite tubes. The explanation on the side of the can implied this did the same thing, which was lubricate sticky keys. All it did was spray a layer of black gunk all over my hands and key, and the key still sticks in the lock, I almost just broke it off in the lock actually. Do not buy!!!! Oh and now the black gunk on the key is rubbing off on my hands and everything inside my purse. Buy graphite in a tube instead.
As it turned out, graphite under pressure is a terrible idea. As careful as I tried to be to put the little extender in a door lock that was sticking, it went everywhere. What a mess. Took over an hour to clean up plus I will have to do some repainting- and at one point, not sure I was going to be able to get it off the tile floor. Next time I will use WD40 (which I did here and it worked fine) or a silicon product. If you need graphite, I remember small squeeze type tubes that at least you can control but I did not seem them at Home Depot.
