Kasp K30050 Graphite Powder, 1 - pack A

yep, works as expected, used on my key then locked/unlocked the door a few times, lubricates well, if feels like the lock is brand new again. Better than wd or other lubricants that will attract dirt and dust and cause the lock to fail.

The Kasp K30050 Graphite Powder works incredibly well. I honestly couldn’t believe the difference it made — the key now glides smoothly into the lock and the mechanism works like silk. A little really does go a long way, so you only need a small amount for great results. It’s easy to apply, it can be a little messy if you squeeze the bottle too hard, so be gentle. It instantly improves stiff or stubborn locks. Best of all, this small bottle should last for many years given how little you need each time. Excellent product that does exactly what it’s meant to do. Highly recommended.

Brilliant stuff. From the moment I put it in the lock it worked instantly. I was really struggling to get the key but once I added the powder the key just glides through the lock like it’s brand new. It can get a little messy and if there’s a slight breeze it can blow off the key before you have a chance to put it in but it cleans off easily-ish enough.

Good, does the job, easy to use but careful cam be messy.

Graphite powder was recommended to me to lubricate locks instead of using oil or WD40 which attracts dirt. It works well, just make sure you wipe the key off the first few times since any excess graphite sticks to it.

Front door key was taking some wriggling to get into the lock all of a sudden. Ordered this and rubbed a bit of this over the key before putting the key in the lock and turning a few times and the lock is good as new! Miracle product.

Excellent product. Key moves in lock like new and very little product was required. Placed kitchen towel under key, sprinkled a little graphite powder along edge and moved key in and out the lock a few times, both sides of door - job done!

My front door Yale lock was very stiff to turn, and hard to press in the key. It was getting so bad I was on the verge of calling out a locksmith. However, this product makes the lock feel like new, after a few squirts into the lock and on to the key. Caution, however, cover up any areas of the door below the lock. It can make a mess, and is hard to clean off. For me that would still be a price worth paying, but simple steps would have prevented that!
