CRC® KNOCK'ER LOOSE® PENETRATING SOLVENT is best for freeing rusted, seized, or corroded fasteners. Every seized bolt feels like a personal challenge. You’ve been there: rusted threads that won’t give, bolts fused by time and neglect, and a supervisor asking how long it’ll take. You can’t waste heat, force, or patience. You just need it loose, and fast. CRC® KNOCK'ER LOOSE® PENETRATING SOLVENT quickly cuts through rust, scale, gum, and corrosion, freeing frozen parts without torching, over-torquing, or breaking components. Its low-viscosity formula seeps deep to do the hard work for you.
