CRC Knock'er Loose Penetrating Solvent

CRC Knock'er Loose lives up to its name. The fast-acting formula dissolves rust and corrosion on contact while lubricating the freed surfaces. Aggressive solvency meets deep penetration.

CRC Knock'er Loose lives up to its assertive name by delivering fast, aggressive action on contact. The formula uses a volatile solvent carrier that flash-penetrates surface corrosion and begins dissolving rust almost immediately, making it the best choice when you want to get in and get out without a prolonged commitment. The trade-off is staying power — it evaporates relatively quickly, so deeply corroded situations benefit from repeated short bursts rather than the slow, all-night soak approach that heavier penetrants offer.
