Crud cutter!
I enjoy picking locks (locksport), so some of the locks are new some are old but quite a few are very old and crusty, having been found on the side of the road or in the dirt. Some of the shackles are completely rusted or frozen to the body of the lock. I've used penetrating oil, carburetor cleaner, brake parts cleaner, all to know available on some of the worst locks. I had heard good reviews on this product and thought I would give it a shot. It works remarkably well in a very short period of time. spray it on let it set for just a very short period of time and you'll begin to see results. Let it soak overnight, and you won't have a sticky lock in the morning. Overall, I have been more than impressed.
