CRC Knock'er Loose 03020 Lubricating Oil Can, 16 oz Red

Works like any other penetrating oil

[This review was collected as part of a promotion.] This knocker loose works great when the nut on the screw that holds my trailer hitch on girls rusty and not usable. A quick spray of this stuff, wait a few minutes and the nut spins right off without too much trouble. I have not had to cut a bolt since starting to use this product. I would highly recommend.

[This review was collected as part of a promotion.] I work on cars frequently and always have bolts that are stuck tight. I love to spray this on and leave for a few minutes it cuts my time in half and saves my knuckles some bruising. It works well and a little goes a long way

[This review was collected as part of a promotion.] I got this CRC KNOCK'ER LOOSE® PENETRATING SOLVENT and it works great. I have used it on even the most stubborn stuck bolts and such and it helps penetrate and break it loose so I can remove it. I will definitely be getting more.

[This review was collected as part of a promotion.] Good product, works well and fast. In those situations where you need to loosen that screw and there is no other way, this lubricant penetrates and quickly helps loosen and move on with your repair. These liquids seep into small spaces between the threaded parts to release them. I recommend it!!!
