Corrosion Block 4-Pack 4-Liter Liquid Refill

Corrosion Block is a clean fluid that actively protects metal using advanced polar bonding chemistry, with synthetic additives that fully penetrate corrosion cells and replace the salt water trapped inside, which is then allowed to evaporate.

A hydrophobic film remains behind to further protect the metal, acting like an "off switch" for corrosion rather than just masking it the way a waxy product does. That clear, moisture-proof film prevents new corrosion from forming, deeply penetrating joints, connectors, and other hard-to-reach spots.

Non-hazmat, non-flammable, and non-toxic, this is a case of four 4-liter refills, a practical way to keep a marina, service shop, or fleet stocked without buying single bottles one at a time. Explore more corrosion protection and lubricants.
