Immunol® 791-J – Mild Cleaner and Rust Inhibitor

Immunol® 791-J is an ultrasonic test tank additive that will dissolve instantly in any kind of water to make a clear, thin solution. Immunol® 791-J is a mild detergent and rust inhibiting chemical for use on cast iron, cast steel and other ferrous metals, but is not recommended for use on aluminum, copper or brass. Immunol® 791-J protects cast iron and ferrous metals submerged in its solution indefinitely and forms invisible, quick drying protective coatings on metal, which insure maximum “indoor” protection. Immunol® 791-J will not cloud in solutions of water at temperatures up to 210 (F) and will not gum or decompose when circulated in water.
