Lock Cylinder Lubricant - Graphite Powder for Door Locks and Hinges - Multi-Purpose Dry Lube for Various Applications

Fine graphite powder for lock mechanisms, locks are better lubricated with graphite powder opposed to oils or water displacers as these soon become sticky and attract dust causing more jams.This bottle has a built in adapter around the bottle allowing deeper penetration into the mech, easing inserting and rotation of the lock.Easy to use once seals found and removed, works well and was reasonably priced.

Could not get the powder into lock. Threw it away. Waste of money .

recently used this lock cylinder lubricant, and while it certainly improved the performance of my lock, there are a few things to be mindful of. The lubricant gave the lock a very silky smooth action, making it much easier to turn. However, applying it can be a bit tricky. I found that the powder blew back onto my hand and the floor, so it’s definitely a bit messy.One thing to note is that you need to be careful not to overapply, as using too much can actually prevent the lock from moving freely. In that case, you'll need to blow out the excess lubricant to get the lock functioning properly again.Overall, it works well, but just be cautious with the application to avoid unnecessary cleanup and issues with the lock itself.

Give my door lock a squeeze and it works like a charm.
