## Description

CRC Knock’er Loose penetrates cracks, machine assemblies, frozen connections, and fittings with its freeze shock action to quickly dissolve rust, corrosion, grime, and grease. The 50-state compliant formula makes it easy to disassemble tools, automobile engines, plant machinery, and other equipment for routine maintenance. This industrial-grade penetrating solvent is NSF H2 registered for use in meat and poultry plants. It works effectively on various metal fittings, hinges, bushings, washers, lugs, nuts, bolts, metal joints, and couplings.

Review: The best I've used so far at getting heavily rusted nuts/bolts apart - For $15 I was blown away at how well this stuff works. I needed to replace some exhaust parts on a nearly 20 year old car and the studs were completely rusted and looked like they would need to be cut out. I sprayed this on all of them and let it sit for a couple of hours before trying to remove them, fully expecting to break at least one of the studs off due to corrosion. Instead, when I came back a lot of the crusty looking rust was gone and after working the nuts back and forth I got all of them off without issue and was able to reuse them. It's an expensive spray but that bottle is a decent size and it sprays on easily. Whatever is in it works extremely effectively at lubricating through the rust and letting you get heavily rusted nuts off. Long story short, I highly recommend this stuff.
Review: Gets the tough stuck fasteners broken loose quicker with less wrenching/cussing! - Seems to work better than other penetrating sprays. I plan to use it as my "first choice" from now on given the positive results so far!
